| OBJECTIVE The purpose of this investigation is to ascertain the existing character of the aquatic ecosystem at Locust Point, Lake Erie prior to operation of the Davis-Besse Nuclear Power Station, Unit 1.
| |
| Included in the assessment are studies of existing plankton, benthos, and fish populations and water quality and recent trends in these parameters. The report contained herein is for the perted 1 January to 30 June 1976.
| |
| PROCEDURE Sampling Station Location In 1974 and 1975 field data were collected from 25 stations, 18 along 4 transects in the open lake, 2 stations in the intake canal, 2 stations in the marshes, and 3 stations along the shoreline (Fig.
| |
| 4 1). Of the 4 transects, one followed the intake conduit, one the discharge conduit, while centrol transects were set up on the east and. west sides of the entire intake and discharge complex. Control west ran due north fecm the shore-end of the intake conduit with sampling stations located at 500 ft (150 m) (Statten 1), 1000 ft (300 m) (Station 2), 2000 ft (610 m) (Station 3), and 3000 ft (910 m)
| |
| (Station 4) frem the shoreline. Sampling stations en the intake were located at 500 ft (150 m) (Station 5), 10C0 ft (300 m) (Station 6),
| |
| 2C00 ft (610 m) (Station 7), 3000 ft (910 m) (Station 8, proposed 4
| |
| intake), and 4000 ft (1,220 m) (Station 9) from shore. Along the discharge transect sampling stations were at distances of 500 ft (150 m) (Station 10), 10C0 ft (300 m) (Station 11), 1500 ft (460 m)
| |
| (Station 12, proposed discharge), 20C0 ft (610 m) (Station 13), and 3000 ft (910 m) (Station 14) from shore. Additional stations were placed 500 ft (150 m) due north of Station 12 (Statten 15) and - 500 ft (150 m) south of Station 12 (Station 16). Centrol east ran perpendi-cular to the shcreline, parallel to the intake, and approximately 2500 ft (760 m) east of the intake. Stations were located 500 ft (150 m) (Station 17) and 1 COO ft (3CO m) (Station 18) from shore.
| |
| Station 19 was located in the center of the intake canal, 10C0 ft (GCO m) from the take shore. Sampling at Station 20 discontinued when it was drained of all water in 1974 Stations 21 and 22 were l located in the northwest and southeast marshes , rescectively. Sta-

| | |
| 3 tions 23 - 25 were on the shoreline at the intersection of the intake conduit and 1500 ft (460 m) to either side.
| |
| In 1976 this sampling format was altered slightly to answer
| |
| - questions which arose following the 1975 field season concerning the intake and discharge (Fig. 2).
| |
| This new station arrangement will provide much more valuable information following operation, and, by initiating it this year, one year of pre-operational data can be obtained. Stations 2,4,5,10, 19, and 20 were eliminated and Stations 26 to 29 were added.
| |
| Station 26 is on the control west transect and located 3800 ft (1,170 m) from its intersection with the shoreline. Station 26 serves as a con-trol station 3000 ft (910 m) northwest of Station 8 (intake) and the same distance offshore as Station 8 (3000 ft). Station 28 is on the discharge transect 4,500 ft (1,380 m) frcm its intersection with the shoreline . Station 28 also serves as a control station for Station 8 as it is 3000 ft (910 m) southeast of Station 8 and equidistant offshore.
| |
| Station 27 is the mirror image of Station 18, with respect to the dis-charge transects and completes a symetrical arrangement of stations around the predicted thermal plume. Station 29 provides a control 3000 ft (910 rn) southeast of Station 13 (plume area). Station 3 is the control to the northwest of Station 13. Stations 3, 13, and 29 are approximately equidistant from shore.
| |
| Water Quality Eighteen water quality parameters were measured mcnthly (Table 1) during the ice-free period of January to June 1976 (March through June) at three Lake Erie sampling stations (1,8, and 13) in the. vicinity of Locust Point (Fig. 2). These parameters and the analytical methods employed for the measurements are listed in Table 2.
| |
| Field Measurements. Water quality measurements were made monthly _ in the field at Stations 1,8, and 13 (Fig. 2). . Temperature ,
| |
| dissolved oxygen and conductivity were measured from a small sur-vey boat with submerged sensors and shipbcard readcut meters. Ols-solved oxygen was determined with a YSI medel 54 meter and conduc-tivity was measured with a Beckman REG-3341 solubridge temperature-ccmpensated meter; each meter was equipped with a thermistor for

| 6 temperature readings. All sensor readings were taken 10 cm below the surface and approximately 50 cm above the bottom. Transparency was determined with a 30 cm diameter Secchi disk towered on a marked line until it was no longer visible. Solar radiation was measured in June at Station 9 with a Lambda model LI-185 quantum /
| |
| radlemeter/ photometer. This sensor measures the quanta of sunl[ght within the photosynthetically active radiation spectrum (4C0 - 7CO mm) reaching various depths in the lake (measured at 1-meter ini;ervals).
| |
| The amount of sunlight is measured in micreeinsteins m-2 sec-1 where one microeinstein equals 6.02 x 10 17 photons .
| |
| Laboratory Determinations. Surface and bottom (50 cm above) water samples were taken at Stations 1,8, and 13 with a 3-Itter Kemmerer sampler at the same time that fleid measurements were being made. . These samples were placed in polyethylene containers and taken to the laboratory for analysis; in most cases, analyses were completed within 24 hours of the sampling time. Fifteen water quality parameters (Table 2) were determined in the laboratory using the procedures prescribed in " Standard Methods for the Examination of Water, 13th Edition" (American Public Health Association, 1971) and in " ASTM Standards, Part 23, Water" (American Seclety for Testing and Materials, 1973).
| |
| * Plankton Plankton was sampled monthly, April through June of 1976 (Table 1), from 12 stations in the vicinity of Locust Point. In addit [on, weather conditions in March permitted a brief sampling period in which samples were collected from Stations 1, 8, and
| |
| : 13. Duplicate vertical tows, bottom to surface, were taken at each station with a Wisconsin plankton net (12 cm mouth; O.080 mm mesh).
| |
| Each sample was cencentrated to 50 ml and preserved in 5% forma-lin. An equal volume of sugar was added to the formalin which was added to the sample to reduce distertion of zooplankters. The volume of each sample was computed by multiplying the length of the tow by the area of the net' mouth. The works of Chengalath et al.(1971),

| |
| Zooplankton. Three 1-ml aliquets were withdrawn fecm each sample and placed in Sedgewick-Rafter cells. The entire cell was scanned under a microscope at 60x while counting and identifying all zooplankters. Incividuals were generally identified to the genus or' species level and reported as number of organisms /1.
| |
| Analytical Methods. Correlation coefficients were computed for the Bacillariophyceae, Chlorophyceae, Myxophyceae, total phytcplank-ton, Rottfera, Copepoda, Cladocera, total zooplankton and several water quality parameters from the results from 1974 and 1975 on an IBM 360 ' computer using the " Statistical Analysis System" (SAS) program which computes these statistics by the method of least squares (Service, 1972). In an effort to explain scme of the varia-tion in the populations frcm these years, multiple regressions were also computed with these plankton components as the dependent varia-bles and water quality parameters, station sampled, and date as independent vartablas. In cil of the analytical computations, only the results of plankton tows from Stations 1, 8, and 12 (13 in 1975) were used as these were the stations at which the water quality was determined. Water samples for chemical analysis were collected at the same time plankton samples were collected. Since the plankton was collected by a vertical tow, bottom to surface, the means of the surface and bcttom water quality determinations from each station were used in the correlations'and regresstens. The results fecm 1976 will be incorporated into these equations and presented in the Progress Report covering the period July 1 - December 31, 1976.

| Benthos Benthos was sampled monthly, April through June (Table 1) from 18 stations in the vicinity of Locust Point. In addition, samples were collected from Stations 1, 8, and 13 in March. Three repil-cate samples were taken at each station with a Ponar dredge (A=
| |
| 0.052 m2). Samples were sieved through 3. U.S . #ao sieve, pre-served in 10% formalin and returned to the laboratory. Individuals were 'Identifled as far as possible (usually to genus; to species where
| |
| ! possible). The number of individuals per square meter was calcu-lated for each of the three replicates by multiplying the number counted in the sample by 19.1. The sample mean and standard devia-
| |
| | |
| 9 tion for each statten were then ecmputed from the 3 replicates. The works 'of Erinkhurst (1963), (1964), (1965), Erinkhurst, Ham ilton, and Herrington (1968), Klemm (1972), Mason (1973), Pennak (1953)
| |
| Stein (1962), Usinger (1956), Walter and Burch (1957), and Ward and Whipple (1959) were used for the benthos identification.
| |
| Fish Fish populations at Locust Point were sampled by 5 methods, gilt nets, shore seine, trawl, hoop nets, and fry net, from April through June 1976 (Table 1). All fish captured were weighed, mea-sured, and identified to species (Trautman, 1957 and Bailey et al. ,
| |
| 1970). Results were reported as catch per unit effort (CPE).
| |
| Gill nets. Experimental gilt nets were set parallel to the intake and discharge pipelines at Stations 8 and 13. Each net (125 ft x 6 ft or 38 m x 1.8 m) consisted of five 25 ft x 6 ft (7.6 m x 1.8 m) contiguous panels [1/2"(1.3 cm), 3/4"(1.9 cm), 1 "(2. 5 cm),
| |
| and 2"(5.1 cm) bar mesh]. The nets were fished for approximately 24 hours monthly. One unit of effort consisted of one 24-hr set with one of these gill nets.
| |
| Shore seine. Shore seining was accomplished monthly with a 100-ft (30.5 m) bag seine (1/4" or 6 mm bar mesh) at Stations 23, 24, and 25. The seine was stretched perpendicular to the shoreline until the shore brall was at the water's edge. The far brail was then dragged through a 90 0 arc back to shore. Two hauls were made at each station. One unit of effort consisted of two hauls with the above mentioned seine.
| |
| Trawl. A 16-ft (4.9 m) trawl was used to collect fish for CPE estimates of abundance and to obtain live fish for stomach analys ts . Four 5-min tows between the intake (Station 8) and the discharge (Station 12) were completed monthly. All four trawls were cons (dered to be one unit of effort. Stomachs were to be taken from a representative number of these fish and preserved in 5-107. formalin prior to analysis.
| |
| Hooo nets. Hoop nets, 2.5 ft (0.8 m) diameter with 1 in (2.5 cm) bar mesh, were set at Stations 21 and 22 in the northwest and southeast marshes. The nets were fished for approximately 24 hours monthly. Cne unit of effort consisted of a 24-hr set with one net. These ' fish were identifled, weighed, measured and released.
| |
| | |
| 10-1 Fry net. A O.75-m diameter oceanographic plankton net (no. 00. ,0.76 mm mesh) was .used to capture tchthyoplankton (fish larvae or fry, and eggs). Five-min circular tows, surface and near-bottom , around Stations 3, 8 (intake), 13 (plume area), 26, 28, and 29 were completed 3 times per month from April through June.
| |
| Additional 5-min tows, surface and near-bottom, were made on 7 occassions from April thecugh June at Toussaint Reef (Fig. 3) One 5-min tow consttNted one unit of effort. Icthyoplankton was preserved in 5% formalin and analyzed under a dissecting microscope. Indivi-duals were identified as far as possible (generally species) using the-works of Fish (1932) and Norden (unpublished).
| |
| RESULTS Water Quality The results of the monthly water quality determinations at Sta-tions 1, 8, and 13 are given in Tables 3-6. Solar radiation measure-ments for Station 9 are given in Table 7. The mean values and ranges for water quality determinations for March through January 1976 are shown in Table 8.
| |
| Plankton i Phytoplankton. Phytoplankters collected March through June 1976 were divided into 28 taxa, generally to the genus level (Table 9).
| |
| Nine taxa were in Eacillaricphyceae, 13 in Chlorophyceae, 1 in Chysophyceae, 2 in Dinophyceae, and 3 in Myxophyceae. Monthly mean pcpulations w'ere highest in - April (103,209/1) and lowest in June (1604.1).
| |
| ~
| |
| ;2cpulations at each station ranged frem 21,247 - 23,558/l in March,
| |
| : j. 82,940 - 135,279/1 in April, 8,705 - 21,163/1 in May, and 1000 -
| |
| 2,118/l in June (Table 10).
| |
| The 8acillaricphycean population was dcminated by Stechanodiscus binderanus in March,1 binderanus and Melostra sp. In April, Olatema
| |
| ; sp. In May,. and Melostra sp. again in June (Table 9). Olatoms com-posed 99.5%, 99.6Si, 88.3%, and 5.S$s respectively, of the monthly mean phytcplankton populations from March to June.
| |
| The Chlorophycean population was dcminated by Pedtastrum sp. in March and June and Mougeotia sp. in April and May (Table '9). Chloro-phyceans were an insignificant compenent of the pcpulation in March and April, constituted 9.9% of the May copulations, and dominated the June population (93.0%).

| * 20 Chrysophyceae was represented only by Dinebryon sp. and was never a significant component of the phytcplankton population (Table 9). They were absent from the population in March and June.
| |
| Dinophyceans were never a significant component of the phyto-plankton population and were totally absent in March (Table 9).
| |
| Ceratium so, and Peridinium sp. were the only representatives of this class.
| |
| Myxophyceans occurred in all months but were never a signift-cant component of the population (Table 9). They were most abun-dant in May when the taxa Achanizomenon/Oscillatoria reached a concentration of 100/l.
| |
| Additional phytoplankton data are contained in Appendix A.
| |
| Zooolankten. Zocplankters collected March through June 1976 were placed into 40 taxa, generally to the species level (Table 11).
| |
| Fifteen taxa were in Rotifera, 12 in Copepoda, 12 in Cladecera, and 1 in Protozoa. Monthly mean populations were highest in May (787/1) and lowest in March (32/1). Populations at each station ranged fecm 30.2 - 34.3 in March, 126.9 - 310.7/1 in April, 615.1 - 1,007.3/1 in May, and 501.3 - 1,C82.9/1 in June (Table 12).
| |
| The rotifer population was dominated by Synchaeta spp. In March, Notholca spp. In April, Keratella cuadrata in May, and Conochiloides sp. In June (Table 11). Rotifers were the dominant zcoplankters (by number) from March to May composing 84.07?, 80.77?,
| |
| and 57.5%, respectively, of the monthly mean populations.
| |
| Copepoda was dominated by Cycicpold nauplit or immatures during all months. Copepods never dominated the zooplankton popu-lation but did constitute 15.1%, 18.8%, 34.5% and 40.0%', respectively of the monthly populations from March to June.
| |
| Cladocerans were only a significant portion of the zooplankton popu-lation in May (5.5%) and June (47.4%). Bosmina longirostris, Eubosmina coregoni, and Daphnia retrocurva were the dominant taxa.
| |
| Protozoans were represented by only one taxa, Otfflugia sp. and were never a dominant zooplankton form.

| 23 plankton, Bacillariophyceans, Chlorophyceans, Myxophyceans, total zooplankton, rotifers, copepods, cladocerans, temperature, trans-parency, turbidity, alkalinity, phosphorus, nitrate and silica. The same variables from 1976 will be added to these computations and presented in the July 1 - December 31 Progress Report, Based on the combined 1974 and 1975 results, the entire phyto-plankton population was significantly correlated (5% level) with 2 of its components, Bacillariophyceans and Myxophyceans (highly corre-lated), and with transparency and alkalinity (negative) (Table 13).
| |
| These coefficients of the total phytoplankton population changed dras-ttcally when the two years were considered separately. In 1974 the r values for total phytoplankton vs. the Bacillarlophyceans, Myxo-phyceans, and transparency were 0.969, 0.021, and -0.213, respec-tively. In 1975, these values changed to 0.073, 0.946, and 0.513, respectively. In 1975, these values changed to 0.073, 0.946, and 0.513, respectively. When these same computations were made on the the 1974 and 1975 results without cens!dering the results from August 1975 (Myxophycean bloom), r for transparency became -0.C71.
| |
| Bacillarlophycean populations frem 1974 and 1975 were signift-cantly correlated (5% level) with the total phytoplankton population, total zooplankton population (negative), cladoceran populaticn (negative) temperature (negative), transparency (negative.),and phosphorus (Table 13). These correlations were most significant for temperature and phosphorus.
| |
| Chlorophgean populations from 1974 and 1975 were signift-cantly correlated (5% level) with phosphorus (negative) and nitrate (Table 13). No other correlations were significant.
| |
| Myxophycean populations from 1974 and 1975 were significantly correlated (5% level) with the total phytoplankton population, tempera-ture, transparency, and alkalinity. The correlation was very high with the total phytcplankton (r= 0.C97) and quite high with transparency (r = 0.604).
| |
| The total zooplankton population and all three of its components, rotifers, copepods, and cladocerans, were significantly correlated (5% level) with temperature. Cepepods and cladocerans were signifi-cantly correlated, while rotifer populations were not correlated with either of them. Bacillariophyceae was the only phytoplankton group

| _R_egression Analysis. Results of multiple regressions with total phytoplankton from 1974 and 1975 and its major components as the dependent variables are presented'in Appendix C, Tables 35 - 42 (Reutter, 1976). Two regressions were develcped for each dependent variable, one with the physical parameters of temperature, turbidity, transparency, station number and date (month) as independent varia-bles and another which added the chemical parameters of alkalinity, phosphorus, nitrate, and silica to the list of independent variables.
| |
| Results of multiple regressions with total zooplankton from 1974 and 1975 and its ccmponents as dependent variables are also pre-sented in Appendix C, Tables, 43 - 46 (Reutter, 1976). One regression was developed for each dependent variable with the physical parameters of temperature, turbidity, transparency, station and date serving as independent variables.
| |
| The multiple regression of the total phytoplankton population against only the physical parameters explained 57.93? (r 2 of R-Square
| |
| = 0.579) of the variation in the total phytoplankton population (Table 35)J Temperature, transparency, and date a.ll centributed signift-cantly (57? tevel). Transparency was the most important single vart-able. With the 4 chemical parameters added to the regresalon 75.0$?
| |
| (r2 = 0.750) of the variation in the phytoplankton population was explainable with transparency, date, alkalinity, and nitrate contribu-ting significantly (5?? level) (Table 36). Transparency continued to be the most significant single variable.
| |
| The multiple regression of the Bacillariophycean population against the physical parameters accounted for 69.2i? (r = 0.692) of the variation in the diatom pcpulation during 1974 and 1975 (Table 37).
| |
| Temperature, turbidity, and date all centributed significantly (5S? level) to this regression with date the most important single variable. When the 4 chemical parameters were added to the equation, 88.83? (r =
| |
| 0.888) of the variability in the Bacillarlophycean population was explained with turbidity, date, phosphorus, nitrate, and silica all contributing significantly at the 5?? level (Table 38). Silica and date were the most important parameters.
| |
| Variations in the Chlorophycean population were the most difft-cult to explain. The regression of the Chicrophycean population against the pnysical parameters accounted for only 46.5?? (r2 = 0.465)
| |
| | |
| 23
| |
| /
| |
| of the variation in the population as only date contributed significantly (5% level) (Table 39). When the 4 chemical parameters were added
| |
| - to the regression, 71.6% (r2 = 0.716) of the variation in the Chloro-phycean population was explained with date, alkalinity, nitrate, and silica contributing significantly to the regression (Table 40). Nitrate was the most important single variable.
| |
| The regression of the Myxophycean population against the physt-cal parameters accounted for 67.5% (r2 = 0.675) of the variation in the blue-green algae population (Table 41). Transparency and date made significant contributions (5% level) to the regression with trans-parency as the most important single variable. When the 4 chemi-
| |
| , cal parameters were added to the regression, 76.5% (r2 = 0.765) of the variation in the Myxcphycean population was explainable with transparency, date, alkalinity, and nitrate contributing significantly (5% level) to the regression (Table 42). Transparency, was the most impcrtant single variable.
| |
| The regressicn of the 5 physical parameters against the total zooplankton population was able to explain 82.9%,(r2 = o,ggg) or the variability in the population (Table 43). Temperature, station, and date centr'ibuted significantly (5% level) to the regression. Date, was the most important single parameter.
| |
| The regression of the rotifer population against the 5 physical parameters explained 59.2% (r2 = 0.592) of the variability in the ratifer pcpulation (Table 44). Station and date contributed signift-cantly (5% level) to the regression with station acting as the most ,
| |
| important single variable.
| |
| The multiple regressicn of the copepod population against the 5 physical parameters accounted for 68.0% (r2 = 0.680) of the variability (Table 45). Only date centributed significantly to the regression.
| |
| The multiple regression of the cladoceran p pulations against the 5 physical parameters accounted for 65.2% (r = 0.652) of the variation in the cladoceran population (Table 46). Temperature and date contributed significantly (5% level) to the regression.
| |
| Values fecm 1976 will be added to these regressions and pre-sented in the 1 July - 31 December 1976 Progrees Report.

| 27 Benthos Benthic macrotnvertebrates collected at Locust Point March through June 1976 were placed into 36 taxa, generally to the genus cr species level (Table 14). The populatten was dominated by oligo-chaetes as the phylum Annelida composed 88.4%, 93.6%, 65.9% and 56.9%, respectively, of the monthly populations from March through June. Tne total benthic macrotnvertebrate population per square meter per station ranged from 57.3 - 191.0 in March, 12.7 -
| |
| 3,081.5 in April, 82.8 - 1,598.0 in May, and 108.2 - 3,724.5 in June (Table 15). Additional data are contained in Appendix D.
| |
| Fish The five fishing methods employed yielded 15,155 fish represent-Ing 21 species during the period April - June 1976. Scientific and common names of the fish are contained in Appendix E.
| |
| Gill Net. Gill netting from April through Jure yielded 796 fish (CPE = 133) representing 17 species (Tables 16 and 17). De catch from Station 8 (intake) totaled 165 fish of 13 species, while 631 fish of 15 species were captured at Station 13 (discharge). Ccnsequently the CPE at Station 8 was 55, while at Station 13 it was 210.
| |
| Shore Seine. The yield from shore seines during the period April through June was 1,451 fish of 9 species (Tables 18-20). De CPE was 43 in April, 378 in May, and 63 in June. Notropis atheri-noides constituted 87.5% (by number) of the 3-month catch, comprising 18.0%, 97.8%, and 72.0%, respectively, of the monthly populations (April - June).
| |
| Trawl. Trawling at Locust Point from April - June yielded 70 fish (CPE = 23) of 9 species (Table 21). Only 5 yellow perch were collected. Notroots hudsonius corstituted 64% of the catch.
| |
| Hooo Net. Only 5 fish of 3 species were collected from April-June from Stations 2I and 22 in the marshes on either side of the plant site. Consequently, the CPE was less than 1 (Tables 22-23).
| |
| Fry Net. A total of 12,933 larvae representing 14 species and 4,838 eggs were collected frem the 6 sampling stations at Locust Point thrcugh June 197S (Table 24 and Appendix F). A total of 8,354

| |
| | |
| 42 larvae and 4,437 eggs were collected at the surface, while 4,479 larvae and 401 eggs were collected near the bottom. No larvae were collected at Locust Point prior to 30 Apell, and, with the exception of one -egg found on 6 April at Station 3 and 3 at Station 28 on 11 June, no eggs were collected until 17 June.
| |
| Notrocis atherinoides and Dorosema cecedianum were the domi-nant species constituting 49% and 44% respectively, of the total larvae captured. Notroots atherinoides first appeared on 11 June, but did not contribute significantly to the population untti 28 June when 6,300 were captured (3,110 in one tow at the surface of Station 3) (Table 60). Dorosoma cecedianum first appeared en 10 May and increased steadily through 28 June.
| |
| Perca flavescens and Stizostedton v_. vitreum, two commerct-ally valuable species, constituted 5% and less than 1% respectively of the larvae. Both species first appeared on 30 April, and for all practical purposes, were gone by 27 May. These 4 species, Occo-sema cecedianum, Notroots atherinoides, Perca flavescens, and Stizo-stedien 3 vitreum comprised 99% of the larvae collected.
| |
| A total of 98 larvae were collected from Toussaint Reef (Table 25). No eggs were collected over the reef. Again, Dorosoma eeoedianum and Notroots atherinoides were the dominant species composing 71% and 20%, respectively, of the larvae captured.
| |
| A complete breakdown of the catch is contained in Appendix F.
| |
| Food Habits Thirty-four fish stomachs from 9 species were examined from .
| |
| April - June (Table 26). Crustaceans were the primary fecd items dominated by Sosminidae, Dachnia spp. , Q retrocurva, Lectodora kindtli, and calanoid and cyclopold copepoids. Additional data are contained in Appendix G.

| 4d DISCUSSION Water Quality Seasonal Variations. The quality of the water in the vicinity of the Davis-Besse Nuclear Power Station during the period March through June 1976 was typical for the scuth shore of western Lake Erie and showed normal seasonal trends. Water temperature rose nearly 20C C during the G-month period from mid-March to mid-June while the dissolved oxygen level fell 5 ppm (Fig. 4). The turbulence of the early spring period and the corresponding high sediment load are reflected in the high turbidity and suspended solids values and low transparency observed for March (Fig. 5). A 5-fold improve-ment in the clarity of the water took place during April and May.
| |
| The biochemical oxygen demand was rather low during the entire period even at the time of high turbidity indicating that the suspended material was largely of an inorgante nature.
| |
| In a like manner the dissolved substances in the water were highest in the early spring and decreased later in the season (Figs.
| |
| 6-8). Alkalinity and pH remained relatively constant while the major tons such as calcium and sulfate decreased by 30-50 percent. Sto-logical nutrients such as nitrate, phosphorus and silica also showed dramatic decreases as spring algal populations uttitzed these materials.
| |
| Station Variations. Stations 1, 8, and 13 are located approxt-mately 500, 3,000 and 1,500 feet offshore, respectively. Generally a slight temperature decrease was noted in an offshore direction, particularly in the late spring. More noticeable decreases were found for such parameters as conductivity, most of the speelfic tons, alkalinity, 800, suspended and dissolved solids and turbidity. Con-versely, transparency increased away from the shcre. Station 1 (nearshore) had the poorest water quality for most parameters while Station 8 (farthest offshore) had the best quality.
| |
| Differences between the surface and bottom water quality were slight because of the shallowness of this portion of Lake Erte. Some depression in the level of dissolved oxygen was noted near the bottom.
| |
| Water Quality Trends. The Chlo State University, Center for Lake Erie Area Research initiated water quality studies at Locust Point in July 1972. Over the past four years most parameters Pave shown typical seascnal trends with only small variations frcm year to I

| Phytoplankton. Phytoplankton populations from March through June 1976 were similar in composition to those observed during 1974 and 1975 (Reutter and Herdendorf, 1975 and 1976). These results will be added to the 1974 and 1975 multiple regressions in order to more accurately describe the variation in the populations from year-to year. These regressions will be presented with the more thor-ough plankton analysis in the Progress Report covering the second half of 1976.
| |
| The most significant finding of the past year was the fact that change in water quality was determined to be the major reason for the large increase in the Myxophycean population from 1974 to 1975.
| |
| 1 The multiple regressions of Myxophycean populations with physical and chemical water quality parameters indicated that 67.5% (physt--
| |
| 1 cal parameters only) or 76.5% (physical and chemical parameters) of the variations in the Myxophycean population could be explained by variations in the water quality parameters. Chandler and Weeks (1945) felt that warm, calm, clear water favored blooms of Myxophy-ceans and Chlorophyceans and the present results support their con-tention. Correlation coefficients indicated that 36.5% (r = 0.604) of the variation in the Myxcphycean population was explainable by changes in transparency, and 11.2% (r = 0.335) was explainable by changes in temperature. This contention was given added weight
| |
| : l. when the temperatures and transparencies of 1974 and 1975 were recalled. The mean water temperatures for April, May, and June 1974 were 8.70 C, 14.60 C, and 18.8 0C, respectively, while in 1975 the temperatures recorded for those months were 7.2 C, U 20.30C, and 21.2 C, respectively. Following this early warming in 1975 came a relatively calm summer with a 2-fold increase in 4
| |
| transparency and a 10-fold decrease in turbidity. In Augyst 1975, the time of the Myxophycean pulse, the transparency was Cu% greater than in 1974 and the turbidity was only 20% of that fcund in 1974 These regressions have helped in the extremely difficult task of predicting phytoplar.kten pcpulations in thermal discharges. By observing the individual 8 values the change in phytoplankton popu-lation' brought about by a change in one cf the independent sariables, while all the other independent variables remain constant, can be estimated (Tables 35-42). Table 35 indicates that an increase in
| |
| . _ _ _ _ _ -~ . - _ , m., ,
| |
| | |
| :>.1 temperature of 1 C, with turbidity, transparency, station, and date remaining constant, will reduce the phytoplankton population by approximately 19,153 individuals /1. Although the accuracy is sus-
| |
| ' pect, (coefficient variation = 119.3%), a helpful estimate is pro-vided.
| |
| Zooplankton. Zooplankton populations from March through June 1976 at Locust Point were similar in size and composition to those observed from 1972-1975 by Hair and Herdendorf (1973) and Reutter and Herdendorf (1974), (1975), and (1976).
| |
| This was the first year that samples were obtained in March.
| |
| The monthly mean value of G2.4/1 was the lowest observed in our years of sampling at Locust Point. However, it was similar to that observed by Reutter and Reutter (1975) during March 1974 at Put-in-Bay, Ohio. The population in April was the largest ever observed but still comparable to 1975. The population in May fell midway between that cbserved in 1975 and those observed in 1973 and 1974 The June population was much smaller than the huge June population of 1975, but felt midway between the populations of 1973 and 1974 In general, the populations observed at Locust Point in 1974 and 1975 were higher than those observed in 1972 and 1973, populations observed in 1976 fell within the range of the previous years. There are several plausible explanations for the variation which has occured.
| |
| Samples in 1972 were collected with a 3-1 Kemmerer water bottle at the surface. In 1973, 1974, and 1975 samplec were collected by a vertical tow, bottom to surface, with a Wisconsin plankton net.
| |
| A brief comparison study in 1973 showed that the vertical tow cap-
| |
| ~ tured approximately 50 percent more taxa than a 3-1 grab (Reutter and and Herdendorf, 1974). The staticns sampled in 1972 and 1973 were similar to those sampled in 1974 and 1975, but not the same. In 1973 the intake and discharge pipelines were being dredged, and in 1972 tropical storm Agnes affected the weather. Also, due to the weather, samples were neither collected en the same day of the month each year nor spaced exactly one month apart. Hubschman (1960) pointed out the tremendous differences which occurred between daily samples, and these samples were taken monthly, while Wieber and Holland (1968) showed that even with replication, . wide variation can occur due to patchiness in population densities. Finally, the unusually high spring populations from 1975 were undcubtedly largely due to the unusual weather conditions associated with that spring and
| |
| | |
| 54 the corresponding changes in water quality (early warming and less turbidity) as the total zooplankton population is significantly ccerelated with both temperature and turbidity (r = 0.587 and -0.328, respect-tvely).
| |
| 8enthos Benthic macrotnvertebrate populations from March through June 1976 were typical for the southwest shore of Lake Erie. They were dominated by oligochaetes and chironomids. The populations were smaller than those from 1974 but similar to those from 1975. The sampling date in March was the earliest samples had ever been col-tected, and the populations observed were the lowest observed to date. However, the March populations were similar to those cbserved in December 1975 indicating that the over-wintering population was quite low (100-2CO/m2).
| |
| Fish As in the past, the species composition and relative abundance in the catch varied by month and by season for all fishing methods indi-cating that a transient population was being sampled. This is not surprising as there is little shelter at Locust Point to support a resi-dent population. Since this was a transient population, extreme caution should be exercised when trying to quantitatively compare CPE results from year to year, as samples were collected monthly.
| |
| In a resident population, collecting samples one month apart would not produce serious errors, however, a transient population can change significantly with time. This is especially true when compar-Ing CPE results for schooling species such as Alosa pseudoharengus, Dorosoma cepedianum, Notroots atherinoides, Perca flavescens, and the larvae of all species. When dealing with these populations and monthly sampling effort one should not apply too much significance to CPE results.
| |
| In reviewing results from previous years, we observed that although 46 different , species have been captured at Locust Point since 1963, there were only 10 species which were of any real numerical or commercial significance (Reutter, 1976). In 1974 and 1975, 7 species, Alosa pseudoharengus, Cyprinus carcio, Corosoma ceoedianum, Morone chrysops , Notrcpis atherinoides, _N. hudsonius ,
| |
| and Perca flavescens, constituted 97?4 and 99%, respectively, of
| |
| | |
| 55 the total number of fish captured. Dorosoma cepedianum was the dcminant species both years. In 1973, Aplodinotus grunniens and Ictalurus punctatus were also considered to be a significant compon-ent of the population (Reutter and Herdendorf, 1974). Herdendorf and Hair (1972) presented commercial fishing results from Locust Point from 1963 - 1972 which showed that Cyprinus carpio, Ictalurus punc-tatus, and Morone chrysops were the dominant species, composing 99% (by weight) of the total catch from that 10 year period. Stizo-stedion 3 vitreum should be added to the above Itst of 9 species due to the emphasis placed on this species by sports fishermen, commercial fishermen, and the Ohio Division of Wildlife. There-fore, the 10 species of numerical and commercial significance at Locust Point were Alosa pseudoharengus, Aolodinotus grunniens, Cyorinus carpio, Dorosoma cecedianum, Ictalurus punctatus, Morone chrysops, Notropis atherinoides, N. hudsonius, Perca flavescens, and Stizostedien v. vitreum. These same species also dominated the catch from the first 3 sampling months (April - June) of 1976.
| |
| TN size of the Perca flavescens population, an important com-mercial population, appears to have varied considerably from 1973 to 1976. Gill nets were the best Indicators of this. During April, May and June, the CPE of yellow perch with gill nets was 12 in 1974, 176 in 1975, and 41 in 1976. Van Vooren et al. (1975) also observed this variability from 1973 - 1975, but their results indt-cated a high 1974 population and low populaticns in 1973 and 1975, the reverse of the present findings. This type of variability is not unusual since Van Vooren et al. (1975) sampled only in spring and fall with a trawl, whereas we sampled. only monthly, and this is a transient, schooling population; .
| |
| Ichthyoplankton sampling has shown the same variation cbserved with gilt nets. Notroots atherinoides, composed 81% of the 1974 larvae, 1% of the 1975 larvae, and 49% of the 1976 larvae. Pecca flavescens composed 5% of the 1974 larvae, 70% of the 1975 larvae, and 5% of the 1976 larvae. Dorosoma ceped! anum larvae Increased greatly to constitute 44% of the 1976 population. Much of this variability in the yellow perch larval population was undoubtedly due to the variability observed in the adult population.
| |
| Although there is tremendous variability in the Ichthyoplankton catches, an important conclusicn can be drawn. There are only three species which contribute significantly to the ichthycplankton pcpulations at Locust Point: Perca flavescens, Notropis atherinoides, and Doro-sema ceoedianum. It also appears that these species occur frcm
| |
| | |
| 56 late April through July in the following order: Perca flavescens, late April to late May; Dorosema cecedlanum, June to late July, and Notroots atherinoides, late June and July (Reutter, 1976). Entrainment of the larvae of these species is most likely to occur at these times,
| |
| : j. It should be noted that the loss of a particular species from the catch does not necessarily mean that the species has left the area, for they may still be present, but large enough to avoid the net. Of, the 3 species, Perca flavescens is~ the only one W1(ch warrants special attention, although entratement of all larvae, if or when it occurs ,
| |
| will be documented after Unit 1 is operational.
| |
| In 1976, control stations were sampled on either side of the intake (Station 8 ) and plume area (Station 13) to determine if unusually large fish larvae populations were occuring due to possible i spawning in the ialp-rap material around these stations. It appears that populations at Stations 8 and 13 were normally within the range set by the control stations indicating that populations occurring' In the vicinity of the intake and discharge were not unusual for the shcre' of Lake Erie near Locust Point.
| |
| j As in 1975, Toussaint Reef was sampled in an effort to com-pare tchthyoplankton populations from a known spawning reef (Baker, j 1969) with those near the shore and Davis-Besse. Again, in 1976, !
| |
| larvae populations near shore were much larger than those on the
| |
| ; reef indicating that larvae migrate to the inshore waters after hatch-j ing .
| |
| The number cf fish eggs collected has changed drastically. In 1975, 190 eggs were collected and 98% of these were from Toussaint Reef. In 1976, 4,838 eggs were collected with none coming from Toussaint Reef. However, the fact that 90% of the eggs collected were taken on one date, 17 June, makes one suspect that this is natural variation caused by the frequency of the sampling schedule.
| |
| The time of the occurrence,of this large catch, 17 June, Indicates that no Perca flavescens or Stizostedlon E vitreum eggs were collected..
| |
| The fact that approximately two weeks later a large number of Notropis atherinoides and Corosoma cecedianum were captured indicates that the eggs were probably of these 2 species.
| |
| Food Habits l
| |
| As in 1974 and 1975, crustaceans were the primary fish food at Locust Point. Senthic organisms were not significantly utilized as a w- - - , , + ,-e-- . - -- -..-.uv. ,, 7.-.- - , ,,,-,,,,..,n,-

Introduction i Because of the many potential pathways of radiation exposure to man from both natural and man-made sources, it is necessary to document levels of radioactivity and the variability of these levels which exist in an area prior to the anticipated release of any i additional radioactive nuclides. To meet this objective, an exton-f sive preoperational environmental radiological monitoring program was initiated by Industrial BIO-TEST Laboratories, Inc. (BIO-TEST) in' July'1972 for the Toledo Edison Company in the vicinity of the Davis Besse Nuclear Power Plant site. The program included col-lection (both onsite and of fsite) and radiometric analysis of air-borne particulates, airborne iodine, ambient gamma radiation, sur-face water, ground water, precipitation, soil, bottom sediments, fish, clams, food crops, vegetation, milk, meat, and wildlife.
| |
| DIO-TEST /NALCO ES completed the first three and one-half years t
| |
| of preoperational monitoring in December of 1975. Results of radio-metric analyses of samples collected from January through June 1976 are reported herein. This report, prepared by Nalco Environmental i
| |
| t Sciences, together with the. previous reports (Industrial BIO-TEST 1
| |
| l Laboratories, Inc. 1973a, 1973b, 1973c, 1973d, 1974a, 1974b, 1975a, and Nalco Environmental Sciences 1975B) will help to establish environmental baseline radiological values prior to operation of

| III. Methodology The sampling locations for the Preoperational Environmental Radiological Monitoring Program at the Davis-Besse Nuclear Power Plant are shown in Figures 1 and 2 and are described in Table 3.
| |
| The type of samples collected at each location and the frequency of collections are presented in Table 4. The sample codes used in this study are presented in Table 5.
| |
| A. The Atmospheric Environment
| |
| : 1. Airborne Particulates Airborne particulate samples were collected at a volumetric rate of approximately one cubic foot per minute on 47 mm membrane filters of 0.8 micron porosity. Vacuum air pumps were used. The filters were collected weekly from twelve locations,
| |
| , (T-1, T-2, T-3, T-4, T-7, T-8, T-9, T-10, T-11, T-12, T-23, and 4
| |
| T-27), placed in individual glassine protective envelopes, and l
| |
| i dispatched by mail to Nalco Environmental Sciences for radiometric I The filters were counted approximately five days after analyses.
| |
| collection to allow for decay of short-lived naturally-occurring radionuclides. In order to minimize counting variables, all samples
| |
| -were counted on the same instrument. The quarterly composites of all air particulate samples from indicator locations (T-1, T-2, T-3, T-4, T-7, and T'-8) and of all air particulate samples from back-ground locations (T-9, T-10, T-ll, T-12, T-23, and T-27) were gamma scanned, using Ge(Li) detector and analyzed for Sr-89 and Sr-90.

| |
| : 2. Airborne Iodine Each air sampler was equipped with a charcoal trap inline after the filter holder. The charcoal trap at each location was changed at the same time as the particulate filters and dis-patched to NALCO ES. The samples were analyzed for iodine-131 by gamma spectroscopy immediately after arrival at the laboratories.
| |
| : 3. Ambient Gamma Radiation .
| |
| Ambient gamma and beta exposure from natural radiation was measured with thermoluminescent dosimeters (TLD). Monthly and quarterly TLD's were placed on 12 January 1976 and annual TLD's on 30 June 1975 at the eighteen locations (the twelve air sampling lo-cationa and Locations T-5, T-6, T-14, T-15, T-24 and T-26). Monthly TLD's were exchanged on 2 February, 1 March, 5 April, 3 May, 1 June, and 6 July 1976. Quarterly TLD's were exchanged on 5 April and 6 July 1976. The annual TLD's were collected on 6 July 1976.
| |
| Each shipment of TLD's included controls which were stored in a shield at the Plant and returned with'the field TLD's after their removal. In-transit exposures were measured by the con-trol TLD's and subtracted from the field TLD measurements to obtain their net exposure.
| |
| : 4. Precipitation Monthly precipitation samples were collected from two locations, casite (T-1) and Put-In-Bay (T-23). (The June sample from T-23 was of insufficient quantity for analysis due to dry 4
| |
| | |
| ' NALCD ENVIRONMENTAL SCIENCES i
| |
| weather). The samples were analyzed for gross beta activity and
| |
| ! tritium.
| |
| B. The Terrestrial Environment
| |
| : 1. Groundwater One-gallon water samples were collected quarterly from wells at four locations (T-7, T-17, T-18 and T-27). The gross alpha and gross beta activities were determined on the suspended and dis-solved-solids of each sample. The tritium content was determined by direct counting of samples using liquid scintillation techniques.
| |
| Strontium-90 activity was determined by milking yttrium-90. The ,
| |
| samples were also gamma scanned for identification and quantifica-tion of gamma-emitting isotopes.
| |
| : 2. Milk 4 One-gallon milk samples were collected monthly from j two herds that gra:e within five miles of the Plant site (T-8 and l
| |
| t T-20) and from milk processing plants in Toledo (T-12) and Sandusky (T-24). Ten milliliters of 37% formaldehyde solution were added i'
| |
| .to each gallon of milk collected at T-12 as a preservative before shipment._ The samples were analyzed by gamma spectroscopy for I-131, Ba/La-140,-Cs-137, and K-40 immediately after receiving them at the laboratory. The samples from T-8, T-20 and T-24 were also analyzed _for I=131 using chemical separation and beta counting.
| |
| Samples-were also analyzed for Sr-89, Sr-90, gross beta, and for stable calcium and potassium. Beginning in May samples were col-Llected on'a weekly basis from T-8 and analyzed for I-131 by chemical 5

| | |
| NALCQ ENVI ACNMENTAL SClONCES separation and beta counting.
| |
| : 3. Fruits and Vegetables Rhubarb was collected on 13 May 1976 at location T-8 and analyzed for gross alpha, gross beta, Sr-90, and gamma-emitting nuclides.
| |
| : 4. Domestic Meat A sample of chicken was collected on 3 June 1976 at location T-8. The flesh was separated from the bone and analyzed for gross beta and gamma-emitting isotopes.
| |
| : 5. Wildlife A representative species of fauna (muskrat) was col-I lected on 20 June 1976 from the vicinity of the site. The muscle was separated from the bone, gamma scanned, and analyzed for gross beta activity; the bone was analyzed for strontium-90.
| |
| : 6. Animal Feed Silage and hay samples were collected on 31 March 1976 at locations T-8 and T-20, respectively. The samples were analyzed for gross alpha, gross beta, strontium-90, and gamma-emitting iso-topes.
| |
| : 7. Soil Soil samples were collected on 3 June 1976 at locations
| |
| ; T-1, T-2, T-3, T-4, T-7, T-8, T-9, T-11, T-12 and T-27 and on 6 August at location T-23. The samples were taken from the top two inches of soil, where vegetation was not growing. All samples were analyzed for gamma-emitting nuclies. The samples collected at l-locations T-1 and T-8 were also analyzed for gross beta activity i 6

| NALCO ENVIRONMENTAL SCIENCES and strontium-90.
| |
| C. The Aquatic Environment
| |
| : 1. Treated Surface Water Weekly grab samples of treated water were collected from four filtration plants (T-10, ' T-ll, T-12 and T-28) and ana-lyzed for gross alpha and_ gross beta activities in total residue, and for tritium. Quarterly composites were gamma scanned and analyzed for strontium-90.
| |
| : 2. Untreated ~ Surface Water Weekly grab samples of untreated water were col-lected from Lake Erie at three filtration plants (T-10, T-ll and T-12) and at three onsite locations (T-1, T-2 and T-3). The samples were composited monthly and analyzed for gross alpha and gross beta activities in suspended and dissolved solids, and for tritium.
| |
| Quarterly composites were gamma scanned and analyzed for stron-tium-90.
| |
| : 3. Fish Three species of fish were collected on 11 May 1976 from Lake Erie in the vicinity of the site and three species were collected on 16 May 1976 in the Put-In-Bay, more than 10 miles dis-tant from the site (as background samples). The muscle was sepa-rated from the bone, gamma scanned and analyzed for grose beta activity; the bone was analyzed for strontium-90.

| - NALCO ENVI ACNMENTAL SCIENCED IV. Results and Discussion The discussion of the results of data collected during the semi-annual reporting period, January through June 1976, has been
| |
| . divided into three broad categories: the air, the terrestrial, and the aquatic environments. Any references made to data collected during previous years for the Davis-Besse Nuclear Power Plant refers to data collected by Industrial BIO-TEST Laboratories, Inc., and NALCO ES, unless stated otherwise in the text. In this report, and in the preceeding report (July-December 1975) the mean values are reported with one standard deviation while in previous reports the mean values were reported with two standard deviations.
| |
| A. The Atmospheric Environment Results of weekly measurements of gross alpha and beta activities in air particulate samples are listed in Tables 6-17.
| |
| Monthly averages of gross alpha and gross beta activities are given in Table 18 and indicate the minimum and maximum values for each location. Weekly activities are presented graphically in Figures 3-14.
| |
| Gross alpha activity showed no definite trend throughout the period and was about the same as the activity reported for the same period of 1975 (mean value of 0.0023 pCi/m3 for all lo-cations as compared to a mean value of 0.0019 pCi/m 3 for all lo-cations in 1975. Mean gross beta activity for all locations for the first quarter of 1976 was lower by approximately a factor of three, (0.041 pCi/m 3 in 1976 as compared to 0.131 pCi/m3 in 1975).
| |
| Mean gross beta activity for all locations for the second quarter 9
| |
| | |
| NALCO ENVIRONMENTAL SCIENCES of 1976 was lower by approximately a factor of four than the acti-vity reported for the second quarter of 1975 (0.:36 pCi/m 2 in 1976 as compared to 0.142 pCi/m3 in 1975). There was little variation in gross alpha and gross beta activities among all sampling loca-tions.
| |
| The results of gamma-spectroscopic and radiostrontium analy-ses for quarterly composited samples from indicator and background locations are presented in Table 19. A representative Ge (Li) de-tector gamma-ray spectrum of composited samples from all indicator locations during the dirst quarter is presented in Figures 15.
| |
| Beryllium-7, which is produced continusously in the upper atmos-phere_by cosmic ray interaction (Arnold and Al-Salid 1955) was the predominant gamma-emitting radionuclide in indicator and back-ground samples, ranging from 0.033 pCi/m3 to 0.120 pCi/m3 for the first two quarters, and was lower than that reported for the same period in 1975 (range 0.120 pCi/m3 to 0.159 pCi/m3). Some addi-tional beta and gamma activity was due to fission and neutron activation products resulting from nuclear detonations (Russell and Bruce 1969). No marked difference in the level of gamma-emitting radionuclides was observed between indicator and background locations during the first two quarters of 1976.
| |
| Weekly levels of airborne I-131 were below the minimum level of detection (0 2 pCi/m 3) at all locations (Tables 6-17).
| |
| Ambient' gamma radiation levels as measured by thermolumines-cent disometers (TLD's) are presented in Tables 20-22.
| |
| Monthly and quarterly TLD measurements averaged slightly lower a

| NALCQ ENVI ACNMENTAL SCIENCES for this reporting period as compared to those for the same period in 1975 (25.4 mrem for. January-June 1976 as compared to 26.7 mrem for January-June 1975) .
| |
| Annual TLD measurements ranged from 33.6 mrem (T-1) to 65.1 mrem (T-12) for the period June 1975 - July 1976,and were similar to those reported for July 1974 - June 1975 (range 38.0 mrem to 67.5 mrem). Readings averaged lower at locations T-1, T-2 and T-3, which is probably due to low radionuclide content in the sandy soil which surrounds these locations, as evidenced by the soil sample values.
| |
| The results of precipitation analyses are listed in Table 23.
| |
| 1 Gross beta activity in precipitation was lower by approximately a factor of four than during the same period on 1975. Tritium acti-i vity in rain water was also slightly lower than during the same i
| |
| period in 1975 (mean value of 0.18 pCi/ml in 1976 as compared to mean value of 0.28 pCi/ml in 1975).
| |
| Values of radiostrontium activities for the first two quarters in 1976. were also lower than those reported for the same period in 1975.
| |
| B. The Terrestrial Environment The results of well water analyses are presented in Tables 24 and.25. Gross alpha and gross beta activities had the following ranges (in pCi/1):
| |
| 1 9
| |
| 11
| |
| | |
| NALCC ENVIFIONMENTAL SCIENCES Alpha Beta Minimum Maximum Minimum Maximum Suspended solids <0.06 <0.2 <0.12 <0.88 Dissolved solids <0.05 <4.1 <1.82 <3.78 Total residue <0.06 <4.3 <1.82 <4.06 Gross alpha, gross beta, and tritium activities were similar to those measured during January through June 1975. Gross beta activity in dissolved solids in the sample collected from T-18 during February 1976 was higher than in water collected from other wells and was similar in activity to that collected in January 1975 from the same well. Strontium-90 and tritium acti-vities were similar to those obtained during the same period in 1974 and 1975. A representative gamma-ray spectrium of well water is presented in Figure 16.
| |
| The results of milk analyses are presented in Tables 26-28 and in Figures 17-20. Strontium-89, iodine-131, and barium-140 activities were below detection limits in all samples. Gross beta activity ranged from 917 pCi/l to 1155 pCi/l and was sinilar to that measured in samples collected during the same period in 1975.
| |
| Strontium-90 activity was also similar to the activity in samples collected from January through June 1975 (Figures 17-20), ranging from 1.19 pCi/l to 4.43 pCi/1.
| |
| A representative gamma-ray spectrum of a milk sample is presented in Figure 21. Cesium-137 and potassium-40 activities ranged from <3.5 pCi/l to 5.6 pCi/l and from 1160 pCi/l to 1320 pCi/1, respectively. Cesium-137 activity was lower while potassium-40 activity was similar to that measured during the same period in 12
| |
| | |
| NALCO ENVIRONMENTAL SCIENCES 1975.
| |
| Due to the chemical similarities between strontium and calcium, and cesium and potassium, organisms tend to deposit cesium-137 in the soft tissue and muscle and strontium-89 and -90 Consequently, the ratios of strontium-90 activity in the bones.
| |
| to the weight of calcium in milk and cesium-137 activity to the weight of potassium in milk were determined in order to estimate the potential accumulation of these radionuclides. The normal concentrations of calcium and potassium in milk are relatively constant, averaging 1.16t0.08 g/l for calcium and 1.5:0.21g/l for potassium (National Center for Radiological Health 1968). As a result of their metabolic similarities, a change in the ratio 1
| |
| of ctrontium-90 to calcium or cesium-137 to potassium would indicate an altered environmental concentration of these isotopes.
| |
| The ratios of strontium-90 to calcium during the first half of 1976 ranged from 1.08 pCi9 0S r/gCa at location T-20 to 4.22 pCi 90S r/gCa at location T-12 and were essentially the same as during the first half of 1975. Ratios of cesium-137 activity to potassium ranged from 1.84 pCi C s/gK at location T-8 to 3.81 pCi l37Cs/gK l 37 at location T-12 and were slightly lower than values reported during the first half of 1975 (range 1.59 pCi l37Cs/gK to 5.40 pCi l37 Cs/gK) .
| |
| Results of analyses of rhubarb are presented in Table 29, and a' gamma-ray spectrum is presented in Figure 22. Gross alpha and iodine-131 activity was below the limits of detection. Gross beta activity was 2.6 pCi/g-wet weight and strontium-90 activity I
| |
| ! was 0.006 pCi/g-wet weight.

| | |
| NALCD ENVIRONMENTAL SCIENCES Results of analyses of a domestic meat (chicken) sample are presented'in Table 30 with the gamma-ray.spectrium of the sample shown in Figure 23. Gross beta, cesium-137, and potassium-40 acti-vities were 2.08 pCi/g-wet weight, <0.04 pCi/g-wet weight, and 6.7 pCi/g-wet weight, respectively.
| |
| The results of analyses of a wildlife (Muskrat) sample are presented in Table 31. A gamma-ray spectrum of Muskrat flesh is presented in Figure 24. Gross beta, cesium-137, and potassimm-40 activities in flesh and strontium-90 in bone were similar to those found in Muskrat callected in March 1974.
| |
| Results of the analyses of cattle feed samples are presented in Table 32. Gross alpha and beta activities, based on dry weight, ranged from less than 0.2 pCi/g to less than 0.3 and from 15.5 pCi/g to 28.7 pCi/g, respectively. Strontium-90 activity ranged from 0.21 pCi/g dry weight to 0.26 pCi/g dry weight. Analyses for gamma-emitting isotopes indicated that most of the activity was due to naturally-ocurring potassium-40. Trace quantities of cesium-137 was present in silage. All other gamma-emitting isotopes were below the minimum detection levels. A typical gamma-ray spectrum of cattle feed is shown in Figure 25.
| |
| Results of analyses of soil samples are presented in.
| |
| Table 33 and 34, a gamma-ray spectrum of soil is presented in Figure 26. Gross beta activity, ranging from 6.3 pCi/g to 30.7 pCi/g dry weight, was similar to the activity in samples collected during the same period on 1975 (ranging from 12.4 pCi/g to 32.0 pCi/g dry weight) . Strontium-90 activity of samples collected
| |
| ~14
| |
| | |
| NALCQ ENVI ACNMENTAL SCIENCES at locations T-1 and T-8 was less than 0.21 pCi/g and 0.27pCi/g dry weight, respectively. Cesium-137 and potassium-40 activities in-samples collected during the first half of 1976 were similar to those in samples collected during the same period of 1975, except for the soil sample collected from T-23 which had a higher cesium-137 level (1.73 pCi/g dry weight).
| |
| C. The Aquatic Environment The results of analyses of surface water samples are given in Tables 35-39 and graphically presented in Figures 27-30.
| |
| Alpha activity of treated surface water samples ranged from less than 0.1 pCi/l to 1.25 pCi/1; beta activity ranged from 1.17 pCi/1 to 4.92 pCi/1. Gross beta activity at location T-ll was slightly higher than at locations T-10 and T-12 (with a six-month average of 2.65 pCi/l at T-ll versus 2.64 pCi/l at T-10 and 2.12 pCi/l at T-12). Tritium activities were relatively uniform for all samples and ranged from less than 0.11 pCi/ml to 0.56 pCi/ml. Strontium-90 activity in quarterly composites ranged from less than 0.2 pCi/l at T-12 to 1.03 pCi/l at location T-ll). No gamma-emitting isotopes were detected above background levels. No seasonal variations were cbserved for treated surface water activities (Figures 27-30).
| |
| Untreated surface water samples were analyzed for gross alpha and gross beta in suspended solids, dissolved solids, and total residue. Ranges of activities were as follows (pCi/1) :

| |
| Alpha Beta Maximum Minimum Maximum Minimum Suspended solids <0.1 <l.22 <0.1 <2.39 Dissolved solids <0.2 <1.26 <l.55 <3.92 Total residue <0.3 <2.16 <2.00 <5.78 Tritium activity in these samples was similar to those in treated water samples, ranging from less than 0.20 pCi/l to 0.48 pCi/1.
| |
| Strontium-9.0 activity in quarterly composites ranged from 0.48 pCi/l to 0.92.pCi/1. No gamma-emitting radionuclides were detected above the background level as is shown in the gamma-ray spectrum of an untreated surface water sample (Figure 31).
| |
| Three species of fish were obtained from Lake Erie in the vicinity of the site and three species were obtained from Put-In-Bay of Lake Erie. Gross beta and potassium-40 activities in the fish muscle were similar in all samples, averaging 2.0 pCi/g and 2.6 pCi/g-wet weight, respectively. Cesium-137 activity in the fish muscle ranged from 0.004 pCi/g-wet weight in carp to 0.09 pCi/g-wet weight in Alewife. Strontium-90 activity in the fish bones ranged
| |
| .i from 0.21 pCi/g-dry weight in carp at location T-1 to 0.75 pCi/g-dry weight in carp.at Put-In-Bay. Fish samples collected and ana-lyzed between January and June 1976 had activities which were similar to those found in fish samples collected during the same period in 1975. Tables 42 and 43 contain the results of fish sample:
| |
| analyses and Figure 32 is a gamma-ray spectrum of a sample of Alewife.
| |
| Gross alpha activity was below the limit of detection in bottom sediment samples collected at location T-1 (less than 2.9 pCi/g dry weight) , while gross alpha activity 'at locations T-29 and T-30 was 10.9 pCi/g and 7.8 pCi/g-dry weight, respectively. The i
| |
| 16
| |
| | |
| NALCO ENVIRONMENTAL SCIENCES gross beta activity was lower at location T-1 (12.5 pCi/g-dry weight) than atl locations T-29 and T-30 (22.1 pCi/g and 16.9.pci/g-dry weight respectively). Strontium-90 activity ranged from less-than 0.21 pCi/g to less than 0.24 pCi/g-dry weight. Cesium-137 and potassium-40 activities were lower at location T-1 than at loca-tions T-29 and T-30. A representative gamma-ray spectrum of a I bottom sediment sample is presented in Figure 33.

We continue to see the variability of environ = ental elements. This last period, with very cold air and soil temperatures followed by an extended period of standing water or soil saturation, exhibited striking changes in the spring flora.
| |
| For some sites and parameters, these data complete the two-year observation period of spring events. A pre-operational profile of relevant environmental factors, based on two to three years of data, will be part of the next report.
| |
| Both high water and construction projects had successively elimi-nated earlier sites that had been selected for reference studies. The wooded site at the Ottawa National Wildlife Refuge, briefly described in the last report, has new been instru=ented; and routine data are being collected. This area, unaffected by site operations, will provide part of the data base from which environmental impact evaluatiens will be made.

| |
| . Department of Biological Sciences 1 , The spring flora was sampled in 213 permanent gaadrats in the five study areas on the Davis-Besse site during the report period. We can
| |
| .now compare species composition in the seedling and herbaceous layers for two successive spring periods.
| |
| i t All methods of collection and data treatment are identical to those previously described (Semi-annual Report, Section A, June 1974). All nomenclature follows Fernald (1950) .
| |
| ', Results and Discussion I
| |
| Imoortance Values (IVs) for woody and herbaceous species for each cc=munity are depicted in Tables A-1 and A-2 for the Spring and Fall of f
| |
| 1975 and Spring of 1976. In addition, IV values for the more abundant species also are presented graphically in Figures A-1 through A-5.
| |
| The fluctuation of species, both in terms of number and importance values, -in relation to changing edaphic conditions, particularly soil
| |
| =oisture, has been alluded to in previous reports. As more data are col-lected, such seasonal variations become more and more evident. Although 4
| |
| some variation was anticipated, the magnitude exhibited in these plant l
| |
| ~
| |
| ! communities was not expected. It appears that large fluctuations in species present, at least on these soils (Toledo and Fulten) , is a natural occurrence
| |
| , in' response to season changes in soil moisture. It would also now appear
| |
| ; that these soil moisture fluctuations =ay override effects of other environ-4
| |
| /
| |
| f
| |
| | |
| A-2 mental factors, such as light mediated through canopy closure and shade tolerances of individual species.
| |
| The Cooling Tower woods best illustrates these trends. In the Toledo soils al.1 three layers (10 cm, 20 cm, and 50 cm) were saturated from 20 February 1976 until 18 June 1976, a period of 17 weeks, including the critical spring germination period (Fiv. A-6). Visual observations con-firmed standing water of up to 6" depth. Although the Fulton soils were not comparably saturated, =oisture levels were high until the middle of May and fluctuated sharply during the remainder of the spring germination and growth period (Fig. A-7) . The dramatic drop in numbers of woedy and herbaceous species and the elimination of many during this Spring is un-doubtedly related to the saturated soil (Table A-1, A-2, and A-3), the greatest changes apparently occurring on the Toledo soils. Such moist woody species as Acer negundo, Parthenocissus quinquefolia, and Ribes ameri-canum now account for better than two-thirds of the total woody importance value, while Celtis occidentalis, a dry-to-moist species is no longer present.
| |
| The same trends are also evident in the Spring herbaceous flora, with the wet species Floerkea proserpinaccides recorded for the first time in this area and accounting for nearly one-third of the total importance values. Other moist-to-wet species as Pilea pumila and Impatiens capensis also have increased substantially over the previous spring. In contrast, dry-type species, such as Acalypha virginica, Scrophularia marilandica, and Saponaria officinalis, are absent from this Spring's flera.
| |
| It would appear that small moisture differences between the Toledo and Fulton soils are extremely important in effecting species distribution, particularly as moisture levels approach saturation. We are now in the
| |
| | |
| A process of separating and reevaluating the last two year's \ by 2 m
| |
| ~
| |
| quadrat data based on soil types. Hopefully the natural species fluctua-tions on the two soils will become more evident and will provide a better basis for future evaluation of this layer of the plant communities under investigation.
| |
| These same trends are evident in the four other site communities under investigation, but to a lesser extent. Visual observation in the Spring of 1976 indicated no standing water or saturated soil conditions, a result of the more sandy nature and slightly higher elevation of the substrate.
| |
| Consequently, the reduction in number of species present is much less dramatic; and in the Hackberry-Box Elder and Hackberry I ccc:munities the number of herbaceous species actually increased slightly (Table A-3).
| |
| Moist-type woody species, such as Acer nequndo, Parthenocissus quinquefolia, Ribes americanum and Cornus drummondii, where present, are generally in-creasing in Importance Value, while dry types, such as Celtis occidentalis and Rubus occidentalis, are decreasing or being eliminated frem the cem= unity (Table A-1). Small fluctuations from these trends are undoubtedly due to minor differences in microtopography, which can have a major effect on moisture retention. Many of the moist-type herbaceous species, as Hydro-phyllym appendiculatum and H. virginianum, that are absent from saturated soil are also increasing, while dry types, as Acalphya virginiana and Saponaria officinalis, are either decreasing or entirely absent for the Spring 1976 sample (Table A-2).
| |
| ( The herbaceous flora in all study areas exhibits a fairly wide range r
| |
| of seasonal and yearly natural fluctuations that appear to be related to r
| |
| l' changes in seasonal. soil moisture, with soil saturation during the spring
| |
| | |
| m A-4 playing a critical role in species survival. As more data are collected, we hope to be able to relate more closely soil moisture levels to herba-ceous species distribution and to determine the range of natural seasonal fluctuations in species composition relative to soil moisture conditions.
| |
| Reference Area The reference area at the Ottawa National Wildlife Refuge (see December 1975 report) was permanently staked and contains 180 sets of nested quadrats covering both Toledo and Fulton soils. Initial identification of woody and herbaceous species has been completed importance values have been calculated, and the list is included as Table A-4. Climatological onitoring instrumentation has been installed. Integration and interpretaion of data will not be attempted until the next report.

| SEMI-AIPJUAL REPCRT DAVIS-SESSE TERRESTRIAL MONITORING COUTFACT JULY 1976
| |
| : 3. Soil Environments Arthur Lirbird Department of Geography The monitoring of the soil environment follows the procedures des-cribed in previous semi-annual reports. Soil temperatures and moisture levels have been =enitored (en a weekly or continuous basis) at the three beach and the two cooling Tower Woods monitoring sites. Soil samples were not secured from any of the sites during the Winter or Spring of 1976, as it was deemed unnecessary to have further preoperational chemical ana-lyses for these seasons. Beginning with the Su=mer of 1976, soil samples will be chemically analyzed each season. In additien, preliminary soil mapping and instrument site selection were carried out at the reference site at Otawa National Wildlife Refuge.
| |
| Soil Temceratures Weekly soil and air temperature averages have been used as in previous reports to su=marize the daily temperature changes and to discuss the sea-sonal changes which have occurred at the conitoring sites. The changes in seasonal average temperatures are assessed at the 10, 20, and 50 cm depths and collectively, when appropriate, for each monitoring site. The sumac cccmunity on the beach and the Fulton soil area in the Cooling Tower Woods have continuous soil temperature records for the weeks of Decerter 5, 1975 to June 4, 1976, which represents a continuation of the data presented in the previous report.
| |
| i i
| |
| | |
| 3-2 Soil temperatures fluctuated in response to air te=perature changes, although the buffering effect of the soil reduced heating and cooling variations (Table B-1). Ranges in weekly soil temperatures generally de-creased with depth (Figures 3-1 and 3-2) . However, low temperature ranges occurred at all three depths in both sites during the period from the week of December 19 to the week of February 13.
| |
| Beach area. Soil temperature in the sumac community of the beach area at the 10 cm depth was below freezing at the start of the data period and cooled rapidly during mid-December. Temperatures remained low until a mid-February thaw where average air temperatures rose to above 40' F (Table B-1). The 10 cm depth refrozo, but by mid-March was thoroughly thawed and temperatures increased rapidly. Temperatures were considerably higher than one year before for the corresponding weeks (See Semi-annual report July, 1975). The consequences of these significantly warmer soil temperatures with regard to vegetation remain to be seen.
| |
| The range of soil temperatures at the 10 cm depth at the beach site was lower than in the winter of 1974-75, as the soil froze early and remained solidly frczen until mid-February (see also discussion of Soil Moisture).
| |
| After-that soil temperatures fluctuated more in response to air temperature (Fig. B-1).
| |
| l The average soil temperature at the 20 cm depth in the sumac community was below the freezing point at the start of the data period and remained i as low or lower than at the 10 cm depth throughout the data period, as in the previous years. The average range in soil temperatures at 20 cm was less than at 10 cm, and was much more pronounced than in 1974-75; but a response to the warming of air temperatures in mid-February was evident.
| |
| | |
| 3-3 There appears to be a peak period of temperature ranges at both the 10 and .
| |
| 20 cm depths from late March to early May, as shown by data from both 1975
| |
| , and 1976 (Figure 3-1).
| |
| The average soil temperatures at the 50 cm depth responded least to air temperature changes throughout the data period. The soil did not freeze
| |
| ; until the week of December 19 and remained warmer than the 10 and.20 cm generally until the end of March. The 50 cm depth responded more slowly to the February thaw. Once the soil warmed at this greater depth, it retained the heat and was warmer than at 10 and 20 cm through April and May; but, as at the shallower depths, temperatures were considerably higher than at the corresponding times in 1975, a response to warmer air temperatures.
| |
| i Cooling Tower *4oods. The more compact and finer textured soils of the Cooling Tower woods responded somewhat more slowly than the beach sands i
| |
| to air temperature changes. The average soil temperature at 10 cm was below freezing at the start of the data period and declined to the mid-20s by mid-December, later than in 1974. Temperatures at 10 cm responded more slowly to the February thaw than on the beach and remained 4* to 5* cooler i
| |
| until the last weeks of the data period, as in the spring of 1975. The average range of temperatures at 10 cm in the tower woods was about the same as for the beach area during the below-freezing peried but increased with the February thaw, though not reaching the range fluctuation for the
| |

| B-4 rapidly in the spring of 1976 than in the spring of 1975. The range of temperatures had minimal fluctuations during the cold winter period but by mid-February had increased, though not as noticeably as at the 10 cm depth. The spring ranges were greater in 1976 than in 1975, in response to earlier than usual warm air temperatures, but as in previous years, were much less than those of the beach area (Figures 3-1 and B-2) .
| |
| The soil at the 50 cm depth cooled = ore slowly than at 10 and 20 cm, as in 1974, the lowest temperatures not occurring until mid-February.
| |
| Similarly the response to warmer spring temperatures was slow. The tower woods soil was colder at 50 cm than was the beach site soil from mid-January to the end of the data period but was considerably warmer in 1976 than in 1975.
| |
| Overall, soil temperatures continued the usual, seasonal fluctuations.
| |
| The 10 cm depth was most influenced by changes in air temperature. The soil site at the beach has a greater amplitude and more rapid response to air temperature changes. The two trends first noticed a year earlier (See semi-l annual report, Ju 1975) have continued and seem to be characteristics that can be expected each year: one, the declining winter response of soil temperature ranges to air temperature ranges; two, the period of large tem-perature changes in Spring in response to warmer air temperatures and a thawed soil. The beach soil is noticeably warmer in late Winter and early Spring than the woods scil (Table B-1) . The low temoeratures ranges o:
| |
| Winter were a response to cold air temperatures; and moisture in the ground froze more thoroughly, making the soil even less responsive to air tempera-ture changes than in 1974-75 and making soil moiscure unavailable (see dis-cussion of soil moisture).
| |
| | |
| B-5 Soil meisture Soil moisture was recorded at the five menitoring locations frcm the week of January 9 to the week of June 4, 1976. A period of five weeks in December and early January had no data collected due to unforeseen circum-stances. Soil moisture in the study sites followed the seasonal patterns discussed in previous semi-annual reports.
| |
| During the winter, moisture fluctuated very little from week to week at the 20 and 50 cm depths in response t,o relatively continuous, below-free:ing soil temperatures; the availability of seme moisture indicates the soil is not frozen solidly. The situation was such different at the 10 cm depth at both sites, unlike in previous years. Cnce the ground thawed in the spring, soils in both areas continued recharging to near 100%
| |
| moisture availability.
| |
| At the beginning of the data period the sumac community showed the impact of the cold air temperatures of early January. The levels of available soil moisture were stabilized due to frozen water in the pore spaces of the soil and in contact with the moisture blocks, as in previous winters. The available moisture remained at about 85% in the 20 cm depth, near 87% in the 50 cm depth, and near 95% in the 100 cm depth until the spring thaw. The 10 cm depth was greatly affected by the cold air tempera-tures, unlike the previous year. The moisture level dropced to O percent as the surface soil froze solidly, making no free water available, and remained at 0 percent until the warm temperatures in mid-to-late February began to free up water. During the spring, moisture available was above 90% at all four levels measured, which was similar to previcus years.
| |
| In the tower woods, the soil moisture available at the 20 cm and 50 cm depths was stabill:ed due to frozen conditions at about 82% and 35%,
| |
| | |
| 1 l
| |
| l B-6 l
| |
| respectively. The 10 cm depth was greatly affected by air temperatures and the soil water freecing. A reading of 0 percent moisture corresponded to the period of January and early Februarf cold temperatures, but moisture available increased with the February thaw. The average decrease, or moisture " drawdown," at all three levels in the tower woods correscends directly with an increase in actual evaporation and seems to have been = ore pronounced in 1976 than in previous years.
| |
| Moisture available increases in the Spring along with warmer air tem-peratures. In 1976 the beach soils seemed to be able to recharge moisture and retain moisture more than soils in the tewer woods, unlike in 1975.
| |
| Reference site Investigations of the soils of the reference site were undertaken in late Spring 1976. A reconnaisance mapping of the area indicated the presence of Toledo and Fulton soils in a pattern stnilar to that found in the Cooling Tower Woods. A complete mapping of soils and correlation of soils with vegetation is in progress.
| |
| Two locations were selected in the reference site area for the installation of monitoring equipment. An insturment shelter has been set up on the Fulton soil to collect climatic data and record soil temperatures using the remote recording thermograph at 10, 20, and 50 cm depths. Moisture blocks were installed at ihe same depths. The second location, on Toledo soil, has moisture blocks and dial thermometers in place. The locations are environ-i mentally similar to the corresponding sites in the Cooling Tower woods.
| |
| Soil chemical analyses for the control site soils will be taken seasonally and compared to the soils of the tower woods.

Terrestrial Fauna S.H. Vessey, D. Flemming, and S. Spaulding Depar*aent of Biological Sciences Introduction With rcre than two year's data collected according to procedures established in the spring of 1974, we have a better understanding of pre-operational variation in species numbers and composition. The only procedural modification from previous reports was an increased effort searching for herptiles and trapping large mammals.
| |
| Amphibians and Rectiles Thirty-four man-hours were spent in April and May searching for amphibians and reptiles in the study area peninsula and along the shore while running large mammal trap lines. Two observers searched together instead of the usual one. Total numbers seen were much higher than in previous years, possibly due to unusually warm weather early in April I
| |
| as well as to the additional observer (Table C-1). More observations were i
| |
| made in April than in previous years in conjunction with the increased i
| |
| large =ammal trapping effort in April. Most of the difference was in the i
| |
| large numbers of Blanding's and painted turtles as well as garter snakes.
| |
| Two' species, the fox snake and the five-lined skink, had not been seen in l previous years. However, neither is unusual in this part of Ohio. The
| |
| | |
| C-2 broad-headed skink observation reported last fall could not be confirmed.
| |
| .Approximately 10% of the garter snakes seen were celanistic, not an unusual statistic in this area. Evening checks in April revealed large numbers of spring peepers in the marsh between the study area peninsula and the dike, as was the case last year.
| |
| Comparing this year with both spring and fall of last year, six species were found in both years. Three species were seen only this year, while two were seen only last year. Scme observations are planned for this summer in conjunction with large mammal trapping. While no attempt is being made to estimate populations, it is important to verify the spe-cies present and collect qualitative data on abundance.
| |
| Winter Birds Peninsula study area circuits were conducted only during January this year to avoid including early or late migrants as had occurred previously (Table C-2). Twenty-four species were seen, probably none of them in the process of migration. Several were flying over the area, and others were feeding there in flocks but roosting elsewhere. At least 14 species resided within the area.
| |
| i Several species were seen this year that were not recorded last year.
| |
| Some, such as the chickadee, nuthatch, brown creeper, and winter wren, are likely winter residents and may simply have been missed or were not in the specific area last year. Others, such as the lapland longspur, were in transient, feeding flocks. Although the number of resident species was similar in both years, =uch =cre turnover in species composition took place from one winter to the next than with su=mer breeding residents. Only about half the winter resident species seen this year were seen last year. These
| |
| | |
| C-3
| |
| _s year-to-year fluctuations in species composition are to be expected but are more pronounced in winter than in summer because of the low numbers of both species and individuals in winter.
| |
| Spring and Summer Birds Observations at the site during the spring migration period are tabulated in Table C-3. No unusual migrants were encountered.
| |
| Three circuits of the study area were made in June, 1976 to estimate resident species. Results are quite sinilar to those of the past three years, averaging 36 species in 1974, 36 in 1975, and 38 in 1976. In each year 5 or 6 species were present in one year but not in another. Often those found one year but not another were stragglers, such as the bay-breasted warbler and rusty blackbird seen this year.
| |
| As usual, species diversity is high, with most represented by only two or three pairs. Red-winged blackbirds, yellow warblers, and tree swallows were the only residents in large numbers. An attempt was =ade to enumerate yellow warblers and red-winged blackbirds this year. If these species can be counted reliable in the future, it will be possible to calculate species diversity indices. Such calculations would provide a composite measure of year-to-year changes in numbers of species and indi-viduals.
| |
| Small Mammals Small mammal live-trapping was done en four consecutive weekends in May. In 480 trap nights 7 different white-footed mice were captured 19 times. The Lincoln-Peterson estimate was 3 mice for the entire grid (Table C-5), down frem 84 the previous fall and 13 the previous spring.
| |
| | |
| C-4 Cur results suggest that the spring population sets the stage for fall (peak) numbers. Thus in 1974 a very low spring pcpulation yielded a low fall population. Very low winter mortality that year resulted in a high 1975 spring density, which increased to unusually high fall numbers (Table C-6). Heavy mortality during the winter of 1975-76 has reduced the estimated population this year to 8. We predict that the fall 1976 populations will be intermediate between that of Fall 1974 and Fall 1975.
| |
| The reference population at Carter Woods, after being lower than Davis-Besse last year, is higher this spring (21 mice per hectare versus 13 per hectare). The two populations continue to fluctuate in phase annually, but the amplitudes are so different that the local environmental variables seem to be controlling.
| |
| Large Mammals Opossums were the most frequently captured large mammal this spring; five individuals were caught eight times (table C-7). Two raccoons, two rabbits, and one skunk also were caught in 494 trap nights.
| |
| The poor trap success (2.3%) is typical for spring, especially for raccoons. Trapping will continue into the fall in an attempt to get better information on population sice and movements of raccoons and opossums.
| |
| Some of these animals range over surprisingly large areas. For e:msple, an adult female opossum (#9) was caught several times within the study area peninsula as well as in the woodlot 1200 m south of the cooling tcwer during a one month period.
| |
| Choice of bait is a variable affecting species caught. The use of sardines is effective in trapping raccoons, opossums, and skunks, while corn attracts raccoons, woodchucks, and rabbits into the traps. Both types of bait will continue to be used.
| |
| | |
| C-5 Cther camals observed in the study area were muskrats, fox squirrel, deer, and red fox (Table C-8). Twenty-eight muskrat houses were counted in the marsh between the dike and the study area in January, up frem 10 the previous year. Since .he level was lowered this spring, we expect another decrease in the nu=bers of muskrats by next fall.
| |
| Three white-tailed deer still frequent the area. The fox sightings ,
| |
| i were of two kits near their den in the study area peninsula. Burrow counts were not made this spring. It appeared that several species were using these burrows besides woodchucks. This su=mer samples of hair from animals entering and leaving burrows will be collected, permitting species identi-fication.

| SEMI-ANNUAL REPORT DAVIS-SESSE TERRESTRIAL MONITCRING CCNTRACT JUNE 1976 D. Atmosoberic Environment Glen R. Frey Department of Geography Introduction Atmospheric fluctuations are fundamenta1'to changes in living compo-nents and soil elements. In the continuing effort to establish both spatial and temporal patterns of normal climatic fluctuations observations are proceed-ing as described in Section D, Semi-Annual Report, June 1974. As in previous reports, discussion is based on recorded meteorological elements which are su=marized by different time periods.
| |
| Ihe long-term weather patterns are typical of most middle latitude stations containing the basic seasonal variations. In addition, within a small region the fluctuations are similar frem one sta: ion to another. While it is expected that the long-term weather patterns will be the same from year to year and station to station, each season and each location has unique variations that make it different from all others no ma:ter how similar the overall climatic conditions.
| |
| On a short-term basis each s tation and individual climatological element will exhibit a variability pattern. Depending on the local conditions surround-ing the station, individual clima:ic elements will have slightly varying inter-rela:icnships, thus se tting a dis tinct pattern of variability. In order to create a profile from which logical assessments can be made concerning artifi-cially induced condi: ions, data analysis must be oriented toward determining i
| |
| variabili:y patterns between different components of the a =ospheric environment i
| |
| | |
| D-2
| |
| -and interrelating their fluctuations.
| |
| Instruments and Measurements 1
| |
| Climatological stations are maintained at three primary locations on the Davis-Besse site. S tation "T" is the base s tation at the microwave /meteorolog-ical tower and is se t up according to weather service standards. It is located in a fenced in area on a grass surface. Because of the great distance from any trees or other obstructions and very level terrain advection processes are at 4
| |
| a maximum. Station "A" is in the cooling tower woods and highly influenced by a continuous and complete forest canopy. The fairly close. proximity to open water and generally. open nature of the woods all influence the climatological measurements. S tation "3" is located in the woods on the sandy soil of a former
| |
| ; beach ridge. The station, in a clearing, does not have 'a forest canopy but in-1 s tead is surrounded by dense growth. The sandy soil, which drys very rapidly, J
| |
| coupled with almost a complete lack of wind currents results in different characteristics. Four supplemental locations on the Davis-3 esse site are set i up with nonrecording rain gauges and read weekly to provide additional data on rainfall patterns. S tation "3G", the reference s tation, at Bowling Green State 4
| |
| University is slightly influenced by proximity to buildings. An additional reference site , S ta tion "0W", was se t up at Ottawa National Wildlife Refuge in i
| |
| June. This station is in a setting very similar to Station "A" close to the j 1ake in a woods with complete canopy cover. However, because of the great
| |
| . extent' of ' the woods it offers more res triction to the wind. Data frem this
| |
| , s tation will be presented in the next report.
| |
| l l Instrumentation in the climate shelters records data continuously on paper i
| |
| s trip charts. From this the -information is summarized by day, week, month, and reporting period for analysis. Recording evapometers were reinstalled according i
| |
| to schedule at the end of April. Graphic presentation of the evaporation data

| |
| Calibration of the hygrothermograph was verified by using an Assman Psy-chrometer and by rotating the back-up hygrothermograph between sites. Evapora-tion instrumentation was also checked primarily by rotating the back-up evapo-meter between sites. Soil temperatures were checked by portable soil ther=cm-eters. Problems developed during this period in the humidity element at S ta tion "T" . The linkage appeared to have some corrosion resulting in slightly lower response. For this reason the meter was brought in at the end of this report period for a thorough cleaning. The back-up hygrothermograph was opera-tional at the site without loss of data. The net radiometer (for =easuring the flow of heat) was broken off of its mour. ting in spring and damaged beyond field repair. It was removed and sent back to the factory for repair and calibration.
| |
| Meanwhile, an alternate was ins talled so that data would not be lost.
| |
| Presentation o f Data The discussion in this report is based primarily on.the period December 5, 1975 through June 4, 1976. The entire month of June is not included because of the time needed for data reduction, analysis , and display. Files of data are maintained and analyzed by day, week, and month. In addition, graphic displays are completed by week and month for summarized normals , s tandard deviations, departures from average, and deviations from Station "T". Data are presented in two basic parts for this report. Part-I: Figures D-1 through D-6 are monthly summaries of normals and variations of the elements together with discriminant ~ function coefficients. Part II: Figures D-7 through D-12 repre-sent weekly interstation deviations with fluctuations being graphed about the values for the base Station "T".
| |
| | |
| D-4 Intercretation of Data ENTIRE PERIOD. Little fluctuation occurred be tween s tations for mos t of the winter period December through April. This period actually began in Septem-ber 1975 (see Semi-Annual Report, Section D, December 1975) and lasted into the firs t part of May 1976. Dif ferences between stations began to increase in the warm parts of April but were not large until May (see Figures D-1 through D-6).
| |
| With the exception of January most of the winter period was considerably warmer than the long-term averages would indicate. Spring conditions, where the lake locations are cooler than the inland locations , were particularly evident in the warmer parts of April and May, Maximum temperatures , in terms of departures from S tation "T", are an 4
| |
| : exce llen t example of the changes in interstation relationships that occurred 4
| |
| throughout this reporting interval (Figure D-7) . Temperatures were relatively close during the cooler part of the year. Once the warmer season approached the maximum temperatures at "3" and "3G" were =uch higher than at "T" and tem-peratures at "A" were much lower. "SG" was warmer primarily because of the in-land location and "3" was warmer because of the isolating effect of trees. "A" was' generally cooler because of the canopy effect of the trees.
| |
| Minimum temperatures from the base station at "T" were much smaller and more uniform. Station "BG" was slightly warmer than the other stations during the winter months because of a heat island effect from the university buildings.
| |
| S tations "A" and "B" were fairly close to "T" in overall departures and fluctu-ation patterns (Figure D-8). As the warmer season approached, all s tations were l reasonably close with the fluctuations that occurred dependent on the local
| |
| . se tting of each s tation.
| |
| 1 I
| |
| Average temperature departures reflected similar deviations to =aximum temperature fluctuations (Figure D-9). S tations "A" and "B" were fairly close to "T" during the winter months, with "30" slightly warmer. As spring and
| |
| | |
| l D-5 summer approached the fluctuation about "T" became larger.
| |
| Similarly, the range in air temperature was small during the winter and then increased significantly from the middle of April through May (Figure D-10).
| |
| Stations "B" and "BG" generally had larger ranges of temperature than "T" during the warmer period, while "A" had a lower range. During the cooler portion of the year the fluctuations were small despite an increase in day to day variability.
| |
| Relative humidity departures Senerally have a high degree of fluctuation because of its dependence on actual mois ture in the air and temperature condi-tions. During the cooler portion of the period fluctuations were generally less than during the war =er time of the year (Figure D-11) . Station "A" and "B" generally had higher relative humidities than "T" or "SG".
| |
| I Dew point fluctuations generally followed a similar pattern to average temperatures (Figure D-12) . Variations were =oderately large throughout the period but as the warmer period approached they increased slightly.
| |
| DECEMBER. Temperatures were generally higher than normal because of two invasions of warm gulf air resulting in new daily maximum te=peratures on the 5th and 13th of the month. Precipitation was above normal totaling almost one inch above the long-term average. Dif ferences be tween s tations were small which is typical of the winter months as illustrated by the discriminant function coefficients (Figure D-1). The greates t dif ference involved S tation "A" which generally had cooler temperatures, slightly higher humidities, and less total precipitation. Maximum temperature at Station "A" averaged 2 F less than most of the stations. This is in direct contrast to the previous year when temperatures were below normal throughout the month and Station "3G" was cooler than the thre stations at Davis-Besse. The individual element that contributed most to the small differences was the l'cw precipitation at "A" . This was caused by interception by the trees.
| |
| -JANUARY. Continuous cold temperatures were recorded each day of the 4
| |
| -n , vr--- - w-r-a t-~
| |
| | |
| D-6 entire month. Precipitation was again above nor=al with a high frequency of precipitation days. Climatic fluctuations were very similar again in January.
| |
| Station "A" with icwer temperature, precipitation, and slightly higher relative
| |
| , humidities is the location that exhibits the greates t dif ference from other stations (Figure D-2). It should be emphasized, however, that all differences are small. January was opposite to both the previous month and to January of last year in terms of departures from normal.
| |
| FEBRUARY. Temperatures the firs t week were colder than averag'e. On the 8th a warm southerly flow moved the thermometer upward and it remained there for the rest of the month. The extremely warm temperatures near the end of the month helped set near record conditions for the entire month. Precipitation was above normal again this =onth principally as the result of one heavy rainfall on the 16 th. Despite very warm and humid conditions, interstation variations are very small and uniform with no outstanding fluctuations (Figure D-3). Precipitation was the mos t variable element because of convective showers in the middle of the month, i
| |
| MARCH. Both maximum and minimum temperatures continued much warmer than normal as in the previous month. With this continued warming the lake locations remained significantly cooler (Figure D-4). Precipitation was again above average for the fourth month in a row. Even though temperatures were warming
| |
| . rapidly going into spring, the winter pattern of very similar climatic fluctu-ations continued as illustrated by the discriminant function coefficients. The larges t dif ferences were be tween Stations "A" and "B".
| |
| APRIL. .The warm spell continued well past the middle of the month until the las t week which was much cooler than average. Precipitation was near normal although the amount from each storm was highly variable amongst the stations.
| |
| Overall interstation variability was small, typical of a winter regime (Figure D-5)., Maximum temperatures, however, showed expected spring characteristics

| |
| | |
| D-7 with Station "BG" averaging 6 ? warmer than the Davis-Besse s ta tions. This f
| |
| ~
| |
| j ,
| |
| was caused by lake effects primarily during the very warm spell during the i middle of the month.
| |
| i MAY. Temperatures averaged near normal but precipitation was nearly cne inch below normal. Spring characteristics continued with warmer inland temper-atures and much larger ranges of air temperature away from the more protected i forest locations. The overall Dsq discriminant function coefficients increased as is to be expected in .the early summer (Figure D-6) . The greatest values were 1
| |
| in connection with Station "B" indicating the influence of the lake. This was most evident on a daily basis when comparing the days with the highest average temp'eratures. Inters tation variation in precipitation' totals also was important in determining the increasing interstation climatic variability.
