'l SEABROOK ENVIRONNENTAL STUDIES 1988 DATA REPORT .
TECHNICAL REPORT XX-1 t
1.0- INTRODUCTION s 1
This~ report presents data collected in 1988 as part of the preoperational environmental studies for'Seabrook Station. It includes. ,
a synopsis of field and laboratory methods, followed by tabular listings:
of the data. Simple statistics such as means and standard deviations are used to show data trends. A summary of findings for,each section is also presented. A detailed analysis of certain key (selected) species, as well as the overall community. composition, will be included in a j baseline summary report, which will follow this-data ~ report, f
In 1988, as in~ previous years, plankton, finfish end' benthic- ;
communities were monitored in the Hampton-Seabrook estuary and nearahore q marine environment. These studies are a. continuation of preoperational studies which began in 1975 and were modified in July 1977. In 1982, further refinements.in certain programs were made with~ respect to sampling frequency and location in order to improve the data base for ,
the formal preoperational-period which began January 1982. The 1988 ,
sampling program reflected revisions made in July 1986, particularly the addition of Station P5 for plankton studies. Both spatial and temporal distributional patterns were the focus of all programs, with certain important selected species monitored most intensively.

2.1.1.1- Field Methods.
Ichthyoplankton samples were collected four times monthly from January through. December-(Table 2.1-1). However, because of severe weather conditions, sampics were only taken three times during April and Dec embe r'. The four sampling dates in each month were distributed among these four quarter-month periods:
1st quarter - days 1 2nd quarter - days _9-15 3rd quarter -_ days 16 4th quarter - days 24-31 Sampling dates in successive quarter-month periods were scheduled to be-
-at least five days apart and no more than 10 days: apart, weather permit--
ting.
On each sampling date, four samples were collected at each of three sites: intake, discharge and farfield (Stations P2, PS, and P7, respectively; Figure 2.1-1). ' Samples were paired oblique. tows taken at night with 1-m diameter 0.505-mm mesh nets. Each not, with a depressor, was set off the stern and towed for 10 minutes while varying the boat speed, causing the nets to sink to approximately 2 m off the' bottom and to rise obliquely to the surface at least twice during the tow. The standard 10-minute tows were reduced to five-minute tows on 19 April.at Stations P2 and P5, and on 25 April at all stations (P2, PS, and P7) to minimize net clogging due to high-plankton density. The volume filtered d !
was estimated with-a calibrated General Oceanics digital flowmeter >
3 mounted in the not mouth, Volume filtered ranged from 230 to 271 m for 3
('
five-minute tows and 401 to 574'm3 for 10-minute tows,. averaging 488 m 3 ovesall. Upon retrieval, each net was washed down irom mouth to. cod end and the contents preserved in 5% formalin buffered with borax.
2.1.1.2 Laboratory Methods i
'lVo of the four offshore samples,_one from each pair, were analyzed from each of the three stations for each sampling date. The t
remaining _two were held as contingency samples, s
Samples-were subsampled with a Folsom plankton splitter _and sorted for fish eggs and larvae using a dissecting microscope. ;
Successive aliquots were analyzed until a minimum of 200 eggs and 100 !
a larvae were sorted or until 200-400 m&. settled plankton volume was. 9 a
sorted. All eggs and larvae were identified to lowest practical taxon j
(usually species) and counted. 'Some eggs, difficult to identify to species, were grouped with eggs of similar appearance {e.g., cunner lt (Tautogolabrus adspersus) and tautog (Tautoga onitis) were grouped with 1 yellowtail-flounder (Limanda ferruginea) and termed Labridae/Limanda eggs). Numbers were then converted to a standard' density-(no./1000'm ). i Notochord lengths were measured to the. nearest 0.5 mm for nine selected species:
Ammodytes americanus, American sand lance Pseudopleuronectes americanus, vinter flounder Limanda ferruginea, yellowtail flounder- l Gadus morhua, Atlantic cod i Scomber scombrus, Atlantic mackerel :\
Tautogolabrus adspersus, cunner ;
Urophycis sp., hake Clupea harengus harengus, Atlantic herring '
Pollachius virens, pollock l
-)
l
.}
Up_to 20 larvas por species were measured from each sample.
An additional 10 larvae were measured for a species in a sample if the- '
third highest length was more than twice the third lowest length,-an indication of higher.than normal variation among the initial 20 measure-monts. This subsampling procedure assures that the number of larvao measured will usually be adequate to detect a 20% difference in mean !
length between stations or dates 80%.of the time (power >= 0.80) with 95%
confidence (significance level = 0.05).

2.2.1.2 Gill Nets Gill nets were set for two consecutive 24-hr period 5 monthly at three stations.(Figure 2.2-1), described in Table 2.2-1. Nets were-30.5 m x 3.7 m and comprised of four panels having stretch mesh dimon- i sions of 2.5 cm, 5.1 cm, 10.2 cm and 15.2 cm. One-net array, consisting i of surf ace and near-bottom nets, was set 'at each station. All nets were set perpendicular to the isobath (Figure 2.2~1). Additionally, one gill not per station was set at mid-depth in February,. June and October. The nets were-attached between permanent moorings and tended daily by SCUBA !
divers.
Otter Trawls 2.2.1.3 The inshore groundfish community was sampled twice per month January through December. Trawling was conducted at night along.
Transects T1, T2 and T3 (Figure 2.2-1; Table 2.1-1) with a 9.8-m shrimp trawl (3.8-cm nylon stretch mesh body; 3.2-cm stretch mesh trawl bag; 1.3-cm stretch mesh cod end-liner). Two replicates were taken at each 9
'l
p 1.
of the three transects, which are described in Table 2.2-1, The not was towed at approximately 1 m/s for 10 minutes, with successive tows taken
'in. opposite directions.. The volume of' drift algae caught in the trawl was recorded.
In four instances (7-September, 22 September, 6 October, 25 1
C;tober) otter trawls were not made at transect T2 due to a large u concentration of lobster gear in the area.
I 2.2.1.4 Sample Analysis / Data Compilation l Finfish were identified.to species, measured and grouped into j size classes. Damaged specimens and fish difficult to identify in the field [ e.g. , hakes (Urophycis sp. ), skates (Raja sp. ), and snailfishes (I.jparts sp.)] were grouped by genus.
Catch data from each of the.three types of fishing gear.used l
in this study were standardized to catch per unit.offort. One unit was .i l
equated to ten minutes of trawling for otter trawls, one 24-hr set for j gill nets :(surf ace, mid or bottom net), or one haul for beach seines. -!
Each transect or station was considered separately, as were the surface, j mid-depth and bottom sets for the gill nets. !

3.1 ZOOPIANKIQN 3.1.1 Methods 3.1.1.1 Field Methods-Macrozooplankton Macrozooplankton collections were made four times per month from January through December, concurrent with ichthyoplankton sampling.
On each date, four replicate (paired-sequential) oblique town were made at night with 1-m diameter 0.505 mm mesh nets at the intake site (Station P2), at the discharge site (Station PS), and at the farfield !
site (Station P7) (Figure 2.1-1)(Table 3.1-1). The nets with depressors were set off the stern and towed for 10 minutes while varying the boat speed, causing the net to sink to approximately 2 m off the bottom and to rise to the surface at least twice during the tow. When nets became clogged due to plankton blooms, tows wete shortened to 5 minutes. The volume filtered, determined with a General Oceanics digital flow meter, 3 3 ranged from 413 to 572 m and averaged 502 m for ten minute tows and 3 3 ranged from 239 to 272 m and averaged 261 m for 5-minute town. Upon retrieval, each net was thoroughly washed down with filtered seawater and the contents fixed in borax-buffered 5 to 10% formalin, depending on plankton density.
3.1.1.2 1.aboratory Methods Macrozooplankton fi Macrozooplankton were analyzed from three of the four tows (randomly selected) at each station for two alternating sampling periods per month. The initial procedure in macrozooplankton analysis was sub-15
I I
sampling for copepods. The sample was concentrated or diluted to a known volume which provided an optimal working sample density (ca. 150 copepods per 1 m& subsample). . The sample was agitated with a Stempel pipette to homogeneously distribute the contents, and one milliliter was removed and examined under a dissecting microscope. Subsampling con-tinued-until at least 30 of the dominant copepod species and 150 total-copepods were counted. When hydrozoans appeared in high densities, preventing Ln even distribution of copepods, the sample was serially split using a Folsom plankton splitter, and the copepods removed for analysis. The samples were recombined after being subject to a quality control check. Cyclopoids and copepodites of smaller calanoid species (which were not efficiently cellected in the macrozooplankton samples),
were not included in the copepod counts. Rarer copepods (Aetidoidae, Anomalocera opalus, Ca]Jgus sp., Candacia armata, Euchaeta sp.,
Harpacticoida, Monstrillidae, and Rhincalanus nasutus) were enumerated subsequently with the remaining macromooplankton. Calanus //nmarchicus, the selected species, was identified to lifestage and sexed. 1 Once copepod analysis was completed, each sample was serially i split, using a Folsom plankton splitter, !.uto fractions which provided counts of at least 30 individuals of each dominant macrozooplankton taxon (as defined in NA1 1984). Generally, 1/4 of the original sample ,
was analyzed, not to exceed 100 milliliters of settled plankton volume.
Macrozooplankton taxa were enumerated by species using a dissecting microscope at magnifications between 6X and 150X. Selected species 3
(Cancer sp., Carcinus maenas, Crangon septenspinosa, and Neomysis americana) were identified to detailed developmental stage (lifestage and/or sex). The abundances (converted to no./1000 m 3) were computed as a mean of all replicate samples which were weighted equally.

3.2 11yAINE IARVAE I 3.2.1 Rgthods I 3.2.1.1 F1 eld -Mt1 Apis The spatial and temporal distribution of bivalve larvae (particularly Hya arenaria) was monitored using duplicate oblique net i town collected weekly from 19 April through 25 October at Hampton Harbor (Station P1), the intake (Station P2), the discharge (Station PS) and farfield (Station P7) stations (Figure 2.1-1). The normal sampling procedure was a two minute oblique tow using a 0.5-m diameter 0.076 mm mesh net, with a 14 lb depressor attached. The net, towed at approxi-mately 0.3 0.6 m/s, was lowered to a depth of approximately 15 m (49 feet) in the first minute and returned to the surface during the second l minute. When net clogging occurred, vertical tows were taken using the !
same apparatus as for the oblique town. The net was lowered to the bottom (approximately 15-18 m) and returned to the surface. Upon i recovery, net contents were thorough 1f rinsed into a 1/2 gallon con-tainer and preserved with 2% borax buffered formalin (with sugar added to enhance color preservation). Samples were kept refrigerated until processed. The volume filtered, estimated with a General Oceanics flowmeter, ranged from 2.8 to 13.1 m and averaged 9.7 m per oblique tow and ranged from 1.9 to 4.3 m and averaged 3.3 3m per vertical tow.
3.2.1.2 Laboratory Methods Samples collected at the four stations were analyzed for the following umboned larvae: Hintella sp., Mytilus edulls, Hodiolus modlolus, Heteranomia squamula, Solenidae, Nya arenarla, Nya truncata, Placopecten magellanicus, Spisula solidissima, Hacoma balthica, Teredo navalls and all other Bivalvia. When the total-umboned larvae caught ranged from 1-300, the entire sample was processed; when total numbers 19
exceeded 300 the sample was split. The bivalve larvae were concentrated by a swirling motion and split from one to ten times to arrive at a randomly selected fraction containing 150-600 umboned bivalve larvae for identification and enumeration. Two subsample fractions were enumerated from each sample, each fraction originating from different halves of the s aniple . Numbers were converted to a density per cubic meter.

centered on the intake (Station P2), discharge (Station PS). and farfield (Station P7) stations (Figure 2.1-1). Collsctions were mado I with a rectangular, 1-mm mesh net (1 m deep x 2 m wide x 8 m long) fitted with a General Oceanics flowmeter and a 40-lb depressor; tow speeds of approximately 1 m/sec (2 kn) were maintained. Tows were made I from the side of the boat in water clear of the boat's wake; the bottom of the net mouth was approximately 0.5 m below-the surface. Tow duration was 30 minutes; area sampled averaged 3729 m2 (ranging from 2943 to 4164 m ).
Upon retrieval, the net was washed down from mouth to cod end and the contents emptied into five-gallon buckets. All debris was thoroughly rinsed before discarding And the remainder was concentrated to approximately one gallon. The samples were then preserved in 5%
formalin and transported to the laboratory for further analysis, j
3.3.1.2 Laboratory Nethods !

4.2 _ MARINE _ MACROFAUNA 4.2.1 Methods 4.2.1.1 Fleid Methods lenthic Desttuctives Quantitative (destructive) samples were collected at six permanent benthic stations during May, August and November; four of the stations (B17, B19. B31, B35) were subtidal and two were intertidal (B1MLW, B5MLW) (rigure 4.2-1 Tables 4.2-1, 2). These stations represented three nearfield (B17 B19, B1MLW) and three farfield (B31 B35, B5MLW) stations. The sampling program for May and November was designed to provide greater resolution of temporal patterns of only the dominant benthic taxa. In August, additional stations (B04, B13, B16 B34) were sampled to provide an examination of the entfre community and 9 increase the overall spatial coverage (Figure 4.2-1, Tables 4.2-1, 2).
During the sampling program, five 0.0625-m2 replicate samples l were taken at each station. Each subtidal benthic station was i permanently marked with a mooring block and an attached surface buoy. I Subtidal sampling sites were preselected randomly by determining uzimuth and distance (within 10 m) from the station block. The sample frame was placed on a horizontal rock surface (samples were stratified to horizontal hard substrate to reduce variability introduced by other substrate types). Epif auna and flora were scraped from rock surf aces and drawn through a diver-operated airlift into a 0.79-mm mesh bag. The mesh bag was placed in a labeled plastic bag, brought to the surface, and sent to the laboratory for preservation and processing. All intertidal samples were collected in the Chondrus zone (mean low water) at Stations B1MLW and B5MLW. Replicate samples were taken at randomly selected sites by placing the 0.0625-m2 frame on a horizontal surface and scraping all epifauna and flora into a labeled plastic bag. Samples l 27
f were then transported to the laboratory for processing. Field notes ;
were recorded on the percent cover of macroalgae and the substrate microtopography within the frame. A general enllection of macroalgal species was made within the station area during May, August and November j (see Section 4.3 on Macroalgae).
i Jubt,j.da_] Transects [
At Stations B17, B19, B31 and B35 (Figure 4.2 1; Tables 4.2-1,-
4.2-2) in April, July and October 1988, six replicate 1-m x 7 m band transects were surveyed along pre-selected random compass azimuths [
radiating from each station's center. At Stations B17 and B35 adult
- 2 Nodlolus mod /olus were counted in each 1-m area along each 7 m transect, ,
a total of 42 quadrats per station. Because of historical evidence of l high densities of Nodlojas modlolus at Stations B19 and B31, only twelve ;
2 1-m quadrats (two per transect) were counted at those two stations.
The total number of urchins (Strongylocentrotus droebschiensis) in each ,
quadrat was recorded (42 quadrats at every st'ation). -
JAtertidal t Non-Destructives >
5 Three permanent 0.25 2m sites, one " bare" rock (in the mean high water zone), one Fucus sp. covered (in the mean sea level zone) and one ,
Chondrus crispus covered (in the mean low water zone) at each intertidal station (B1HSL and B5HSL), were sampled non destructively during April, July and December (Figure 4.2-1; Tables 4.2-1, 4.2-2). The presence of i fucold algal holdfasta (Fucus sp., T. resiculosis, F. distichus var.
edentatus and Ascophyllum nodosum) and gastropods (Acmaca testudinalis, ;
Lit torina sp. l Juvenile), L. littorea, L. obtusata, L. saxatills and Nucella lapillus) was recorded for each of 16 subdivisions of the fixed O'.25-m quadrat. The overall percent cover of the fucold algae (prior to f l disturbance) within the quadrat was also noted. General observations over r L
b 28
the sampling area were recorded and photographs taken of each tidal zone (MW, MSI., MIN) and permanent 0.25-m2 ,gg,,
The occurrence of "understory" algae (Chondrus cr/spus, Mastocarpus stellatus and " ephemeral" algae), Balanus sp. and Mytilidas 2
within the 0.25-m quadrats was determined by laying a 2.5 m line within the fixed quadrat and recording the presence of organisms under each of 50 points on the line. The line was laid three times for a total of 150 records per quadrat. The percent frequency of epiphytes on fucold algae, was determined (before any algae was disturbed) wit'hin each quadrat by the " point contact" method. In this case, the 2.5 m line was laid 2
within the 0.25 m quadrat once and the presence of epiphytes on the fucold algae under each of the 50 points on the line was recorded.
jlottom panels To obtain information on recruitment of sesnile benthic organisms (short term panels) and their patterns of succession (long-term panels) on hard substrate, bluestone plates measuring 50 cm x 50 cm were placed by SCUBA divers, on steel frames set into large cement arrays, 0.5 m off the bottom, at Stations B04, B19, B31, and B34 (Tables 4.2-1, 4.2-2). At each station, short-term panels were placed on the i prisy in December 1987, and April and August 1988 for approximately 120 days, and collected in April, August and December of 1988. A long-term panel was placed at each station in August 1987, and collected in August 1988. Each panel was placed by divers in a sealed container while still on the bottom to eliminate loss of organisms in transit to the surface.

r 4.2.1.2 ha) oratory Methods Bentjite Destructives All marine subtidal and intertidal destructive samples were washed over a 1.0 mm sieve prior to preservation. Organisms collected in all hard substrate quantitative (destructive) samples were first separated from % algae collected within the sample. Faunal samples' were then preserved in 6% buffered-formalin; algal samples were frozen.
f During Hay and November destructive sampling periods, only dominant species were identified and counted. Animals not designated as I dominants were left in the samples and archived for future reference. ,
The dominant species were determined from previous studies to be those ;
I taxa which are the most useful as indicators of overall community type in the study area. Species counts for each replicate were converted to '
abundance per square meter before any statistical computations were j made.
During August, all dominant species as well as other non-colonial organisms in the faunal quantitative samples were identified to the lowest possible taxon and counted. When parts of animals were [
, found; only heads, central discs or hinged shells were counted. i 1
l Colonial taxa were identified and listed as present with a count of i zero. All counts were converted to abundance per square meter. The '
abundance of spirorbid polychaetes at Stations B19 and B31 wsa estimated from ten algal subsamples, one subsample from each field replicate. At "
each station the spirorbid polychaetes present on the algal species Phy11ophora sp. were counted and identified and the density was con-verted to an areal estimate based on the dry weight of the algal sub-l samples.

i Syblidal Transects Subtidal transect data were tabulated separately for each 1-m 2 area along a transect. The following velues were calculated: '
- For #odfolus mod /olust mean density and standard .
deviation per square meter; total number of animals divided by number of 1-m' areas sampled (Stations B17 and ,
B35, n = 42 and Stations B19 and B31, n = 12).
For Strongylocentrotus droebachiensist mean density'and standard deviation per square metert total number of ani- :
mais divided by number of 1-m' areas sampled (n = 42).
P t
IntertLdaUmpdpos_inc j ives Intertidal non destructive data were tabulated separately for each 0.25 m sample. The following values were calculated:
Percent frequency (% F) for fucold algae and gastropods =
the number of subdivisions in which species occur divided by 16. multiplied by 100.
Percent frequency (% r) for "understory" algao, Balanus sp. and Mytilidae = the average number of points (of three replicates) under which the species occurred divided by 50, multiplied by 100.
Percent cover (% C) = field estimate for the entire O.25-m' sample.
Botton Pigels Short-term and long term panel plate? were analyzed non-destructively for Balanus sp. and Spirorbidae. Densities were estimated 2
by placing a 0.25-m polyethylene sheet divided into 100 equal sized cells over the panel surface, and computing the average number of l organisms over six randomly selected cells and multiplying by 100.
Percent cover of Hydrozoa and Bryozoa, plus any abundant algae species ,
31 i
l on long-term panels was estimated in the following manner. A 0.25 m l polyethylene sheet marked with 100 randomly placed circles was placed over the panel surface and the total number of instances an organism occurred within a circle was determined. All panels were analyzed ;
I destructively for sessile bivalves and solitary chordates. Densities of sessile bivalves at selected stations were estimated by placing the (
sample into a tray of 36 equal sized cells, computing the average number of organisms over five randomly selected cells and multiplying by 36 i (Appendix Tables 7-12, 7-13). Animals were identified to species and enumerated. ;

4.3 NARINE MACROALGAE 4.3.1 Nothods 4.3.1.1 Field Methods QuaititativeSampling
.]
Quantitative sampling of subtidal and intertidal macroalgae was accomplished according to the methods in Section 4.2.1. In May, August and November, selected subtidal stations (B17, B19, B31 B35) were sampledt in August samples were also collected at four additional subtidal stations (B04, B13 B16, B34). Intertidal samples were col-lected at Stations BlMLW and B5MLW for all three sample periods. Five replicate samples were collected at each station and general collections of macroalgal species (including fucold species and kelps) were compiled for subtidal and intertidal stations in May, August and November. In addition, macroalgao from MSL (mean sea level), and from tide pools in the MLW (mean low water) and MSL zones,-were collected at each inter-tidal station. In August, general collections also included crustose algal species. A summary of methods for macroalgal studies is shown in :
Table 4.3-1.
l Subtidal Trar3 sects Dominant subtidal "understory" algae were sampled non-destruc-tively at Stations B17, B19, B31 and B35 in April, July and October.
Six replicate baind transects (1 m x 7 m) were surveyed along pre-selected random compass azimuths radiating from the center of each.
station. Along each transect line were 20 equally spaced markings !
(total number per station = 120) under which the occurrence (e.g., ,
presence / absence) of the dominant "understory" macroalgae (Chondrus crispus, Phyllophora spp. or Ptilota serrata) was noted. The substrate 37
_ -_ a
L type (rock, cobble or mixture) was also noted for each of the six transects at a given station.
All kelp species within each 1-m 2quadrat along the transects were identified, counted and percent cover was recorded; any Laminarla sp.
less than six inches and Agarum cribrosum less than three inches were categorized as " juvenile" and not recorded. Because of historical evidence of high densities of Agarum cribosum at Stations B19 and B31 only twelve 1-m2 quadrats were sampled for A. cribosum at each of those two stations (2 per transect).
Intertidal Non-Destructives Three permanent sites (0.25 m2 ), one " bare" rock, one Fucus spp.-covered, and one Chondrus crispus-covered, at each intertidal station (B1MSL, B5MSL) were sampled non-destructively during April, July and December (see Section 4.2.1). Intertidal transects were sampled simultaneously during those months to record the frequency of the fucoid algae (Fucus spp and Ascophy11um nodosum) over a larger band of the MSL zone. A 9.5-m line was laid between two fixed points'in the MSL zone and the occurrence of plants under each of 20 points on the line was recorded. Three replicate transects were recorded.
4.3.1.2 Laboratory Hethods I
Quantitative samples were initially separated into plant and ;
animal fractions (see Section 4.2.1). The macroalgal portion of each sample was preserved by freezing. Sample analysis included sorting,. j identification and dry-weight biomass determination of each species (to 0.01 g); plants were dried at 105'C for approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

- Parcent frequency (% F) for " ephemeral" algae = the average number of points (of three replicates) under which the species occurred divided by 50, multiplied by 100.
- Percent cover (% C) = field estimate for the entire 0.25-m8 sample.
The mean percent frequency of fucold algae present in April, July, and December at fixed transect sites was calculated based on the mean of three replicates of the number of occurrences a given species was present along the transect line, divided by the total possible occurrences (20), multiplied by 100.

j Species lists were complied from collections (general and destructive) in May, August and November. The presence or absence of crustose algae was also recorded from general collections in August.
All crustose algal species, along with any other unknown species, were l Identified by Dr. Arthur C. Mathieson,-Jackson Estuarine Laboratory, University 'af New Hampshire. In quantitative samples,. taxonomic " lump- i ing".was necessary in some cases: algae identified as Chaetomorpha spp. '
are a complex of C. aerea, C. brachygone and C. linun, however, C. aerea has not been collected since 1981. Phyllophora-spp. includes j P. pseudoceranoides.and P. truncata. Qystoclonium purpurouw v. cirr-hosum has been reported herein as Qystoclonjun purpuroun, since this~is the only variety reported in this locale and in fact may be an ecotype.
4.3.1.3 Data Analysis Quantitative Data lhe biomass value for each algal species from all destructive samples was converted to biomass per square. meter before any calcula- I tions were made. The mean, standard deviation and percent composition of biomass per square meter was determined for each algal species at each station during each sampling period. In addition, the mean, standard deviation and percent composition of biomass per square meter was calculated separately for all statione sampled during August. The overall mean biomass per square meter (all species combined), standard deviation, sum and the number of species was computed for each station for each sample period. l
[
A list was compiled of all unique macroalgal species identi- ,
fled from all general collections and destructive. samples at each of the intertidal and subtidal stations sampled. The total number of unique taxa from all destructive samples and general collections at each 3
station was calculated by pooling all collections at a given station and 39 F

Fouling panels were collected from January through December at Stations B04, B19, B31, and B34'(Figure 4.2-1). Panel faces consisted of 10.2-cm x 10.2-cm roughened Plexiglas plates bolted to a !
pine block of equal size, both attached by a PVC tube to an array system !
designed to maintain panels vertically at a constant distance from the ocean floor (see NAI 1980). Panel depths below the water surface ranged
]
from 3 to-6 m depending on the tidal stage. Two array systems were .}
deployed at each station with one considered a main system and the other an auxiliary.
Both were treated equally. Panels were collected and 4
replaced on a monthly basis by SCUBA divers. Before removing a panel', l divers covered it with a 0.79-mm mesh bag to prevent loss of attached plants and animals. -On deck, the panel and mesh bag were put in n' '
labeled plastic bag and stored in a cooler until delivered-to the- i laboratory for processing and preservation (within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). Divers also cleaned the array system monthly to-reduce weight and keep the

the adjacent support structure. i Two different panel types were employed at each station (Table 4.4-1): short-term panels (ST), exposed for one month, and monthly ;
sequential' panels (MS), exposed for increasing time periods from 1-12 months depending on the month collected. Two replicate short-term panels and one monthly sequential panel were collected monthly at each !
of the four stations. In Decenber, an additional MS panel was collected per station. Total days of exposure for each panel type.at each station j are listed in (Table 4.4-2).

All' panels were' refrigerated until processed. Each panel _was ' l dismantled and the panel face was photographed. All-fouling material was scraped off the wood block and the PVC tube. The scraped epibiota1 was rinsed ~over a 0.250-mm mesh sieve prior to storage or processing.
For short-term panels, this-material, and the intact penel' face were stored in one container. For monthly sequential panels, the_ intact-panel face and the scraped epibiota were stored intseparate containers.
All sample portions (for ST and MS) were preserved in 6% buffered!
formalin. The wood blocks from all MS panels _were dried, split and examined for the presence'of wood boring organisms. All Laminarla sp.,
except juvenile plants (<3 cm long), were. cut of f' the monthly. sequential' panels as close to the holdfast _as;possible without disturbing the i
fouling community. Laminarla sp. blades were rinsed to remove motile i fauna, counted and frozen for subsequent. biomass analysis.
A summary of analyses completed by replicate isLincluded in Table 4.4-1. All animal' species collected on both ST replicates'each' '
month and one December MS replicate, were identified and enumerated. l
)
Colonial animals were enumerated by determining the percent frequency of.
occurrence on the panel face using a'100'cm2 grid frame.
Colonial species were recorded as "present" when found irt the sample but not '
l directly on the panel face. Monthly sequential panels were evaluated i taxonomically using quantitative techniques similar to those<used by Mueller-Dombols'and E11enberg (1974) and Rastetter and Cooke (1979). A 100-cm grid frame was placed over the MS panel face to determine the }
percent frequency occurrence of selected dominant (colonial and non-colonial) species. Counts were estimated for non-colonial species and- f an abundance range was recorded. Selected dominant species were recorded as "present" when found in the sample,1 but not on the MS panel !
face. Individuals recorded as "present" were not included in calcula- f tions of mean count. l 1

Morphological studies were conducted for a random sampling of 200 Hytilidae and 100 Jassa falcata collected from MS panels. Mytilidae' shell lengths were measured and recorded in 0.1-mm increments. Jassa falcata were also measured to the nearest 0.1'am and separated'into the following groups: males, females, ovigerous, females with brood, and immature (those' lacking distinct sexual morphological characteristics).
Female amphipods with' eggs or brood were recorded as such, though actual
{l egg and brood counts were not made. All Jassa falcata and Mytilidao. 'i measured at less than 1.0-mm were grouped and recorded as <1.0 mm. !
i Individuals in that size-class were not included in calculations of mean
{
1engths. !
Macroalgae were. identified to species where possible for '
short-term and monthly sequential panels.- Percent frequency-on the panel face or a "P" for.present (if found in the sample, but not on'the j panel face) was recorded. Laminarla sp. blades were counted,-but not l L
measured in 1988, Diatom percent frequency on the panel face was l recorded for ST and MS panels. As with colonial = animals, percent !
2 frequency was obtained by placing a 100-cm grid frame over the panel 3 face. Each square centimeter represented.one percent frequency occur-rence of algae or diatoms.
l x)
Counts of Mytilidae from December MS panels were determined by-the volumetric analysis of randomly selected subsamples within .
designated size classes. Degree of randomness, and therefore statistical validity of the subsampling was determined by testing.the ;
means of five aliquots of 100-125 individual mytilids with a Poisson Distribution at a 95% probability using a chi-square comparison.
Biomass dry-weight from ST (one of each pair of replicates) and all MS panels was determined after taxonomic processing. Fauna and flora scraped from the panel face were recombined with the frozen Laminarla sp. blades and sample scrapings, then dried at 105*C to a ,
constant weight. A mean weight was obtained for the two December MS 1
panel replicates. 1 l

4.6.1.1 Field Methods.
The epibenthic crustaceans Romarus americanus, Cancer borealis and Cancer frroratus were collected at two offshore areas from 5 June to 30 November. Fifteen traps were fished approximately three times per wcek, weather permitting, near the discharge site and off Rye Ledge at i
Stations L1 and L7, respectively (Figure 4.6-1). Lobsters were sexed- 1
\
and carapace lengths were recorded in the field in 1/2" size classes'- i ranging from 2" to'4-1/2" as follows:
Size Class Range f L

4" ' >3-5/8" to 4-1/8" 4-1/2"- >4-1/8
i- i Lobsters measuring greater than 3 3/16" were classified as " legal" >
according to the State of New Hampshire regulations. Egg-bearing-females were recorded. Crabs were taken to the laboratory and frozen to i be measured later.
Green crabs, Carcinus maenas, were collected.at four estuarine locations, two traps per location, on the perimeter of Flat 2 in'Hampton llarbor (Figure 4. 6-2) . The traps were fished biweekly January-December except for February and March when historically no crabs have been found. Samples were taken to the laboratory and frozen to be measured l
later.

4.7 fl'A. AREMARIA Information on the larvel' stage of Nya arenarla is contained in Section 3.2 (Bivalve Larvae) ci this report. Similarly, information on the principal non-human predator on Nya arenarla, the green crab, Carcinus maenas, is contained in Section 4.6 (Epibenthic Crustaceans).
4.7.1 liethods 4.7.1.1 Spat and Adult Survey-The five largest flats in the Hampton-Seabrook Estuary (Figure 4.6-2) were surveyed in the late fall to obtain information on Nya arenarla spat (1-25 mm) and juvanile and adult clams (126 mm). ' Aerial photographs taken of the flats in September 1984;at mean low water were used'to construct sampling maps. Flat acreages were calculated using those maps and an electronic planimater with digital readout.
Soft-shell clam populations ~were characterized by sampling randomly-chosen stations on each flat. The number of stations sampled on each flat was determined on the basis of-the variance observed at that flat in the 1987 clam flat survey. The numbers of samples processed for each flat are listed in Table 4-7.1.
Flats 3 and 5 were not sampled for adults.
Spat samples, three 10.2-cm diameter x 10.2-cm deep cores, (4 inch diameter x 4 1rch deep) and adult samplo , one 0.18-m 2 area x 2
45-cm depth, (2 ft x 18" deep) were collected concurrently, placed into labeled plastic bags, and transported to the field laboratory for enumeration and measurement. These measurements were used to generate length-class distributions.

( Individual sample counts were converted'to numbers,per square' l
foot (0.093 m ) and to estimates of harvestable clams (bushels per acre)
- tsing a table of clam volumes (by size) provided in Belding (1930). To 5 express results in terms-of standing crop (bushels of clams on the.-
entire flat), the estimate was multiplied by> flat surface' area _(acres).
The annual-sampling program, due:to the randomization,of sampling effort, provided_a representative quantitative estimate 1of spat
- densities for the llampton-Seabrook flats as. a whole, which- included areas both favorable and unfavorable to spat settlement.
)
-4.7.1.2 S_ pat Survey - Fixed Stations i
I To compare population densities of spat (seed) clams,Laurveys- --
were conducted in late October.on two Hampton-Harbor Flats, and on three y l
flats in an adjacent estuary in northern Massachusetts (Figures.4.6-2,
[
4,7-1 and Table 4.7-2). Samples'were-: collected and processed using.tho' same methods employed in the spat and adult survey described above, with an additional 1-cm deep x 35-mm' diameter core taken for' analysis of-i' t newly-set soft-shell clam spat (<1.0 mm).
[ The fixed station program provided relative estimates-of geographical distribution with emphasis on-high yield locations.
^
Sampling sites were fixed on-the basis of historic evidence of high l
productivity.
l .
l 4.7.1.3 Clammer Counts i
f The impact of human predation on the Nya arenarla population .
was gauged every Friday and some-Saturdays during the clamming season-(September through May) by recording the number of clam diggers on each flat approximately one half hour before low slack tide. Counts were l
62 2 --"t. y
~
l e
taken at this time based on data obtained in'1984 which showed that the ,
highest numbers of clammers were on the flots just before low tide. The total number of digger trips in a season is the. sum of Friday trips plus I
an estimate of Saturday trips. -The estimate of Saturday. trips is based on the ratio-between available sets of paired Friday / Saturday counts from 1983 to 1988.

Near-surface (-1 m) water samples were collected during -j daylight hours with a General Oceanics 8-t water sampler from the j
?ntake, i discharge, and farfield sites, Stations P2, P5 and P7, respec- l tively (Figure 2.1-1). Collections were taken once in-January, February j
and December and twice monthly from March through November in .
conjunction with macrozooplankton/ichthyoplankton sampling (Section.
l 3.1.1.1). From each water collection, (3.785 E) one gallon was reserved-1 for chlorophyll a determinations, 500 ml reserved for nutrient analysis. j At all stations, temperature and conductivity profiles lwere taken four times per month with a Beckman thermistor / salinometer (Model RSS-3) in conjunction with macrozooplankton/ichthyoplankton sampling
{
(Section 2.1.1). On 19 and 29 December, profiles were;taken-with a YSI (Model 33) S-C-T Meter. Due to severe weather conditions, samples were ,
not taken on 15 April and 15 December. Duplicate dissolved oxygen l sampics and a salinity sample were also collected near-surface and j near-bottom. Dissolved oxygen samples were fixed in' the . field with i
manganous sulfate and alkaline iodide-azide. '
i 5.1.1.2 Laboratory Methods Chlorophyll a water samples were divided into two 900-mt - ,

- 1) The overall abundance (annual mean of 7321/1000 m for all species combined) of fish eggs in 1988 was only slightly higher than that observed in 1987 (6954/1000 3
m ). This abundance was 31% lower than the mean for the twelve year period between 1976-1987 (10641/1000 m3 ) but 3
was 43% higher than the 1984 mean (5131/1000 m ), the lowest overall abundance recorded during this period.
- 2) The three taxa which contributed the highest number of eggs in 1988 were cunner /yellowtail flounder (Labridac/
Limanda and Tautogolabris adspersus), hake (Urophycis and Enchelyopus/Urophycis) and Atlantic mackerel (Scomber ;
scombrus), together accounting for 94% of eggs collected during the year. These three groups have consistently N Sn dominants in past years. Two of these three groups decreased slightly from 1987 to 1988. Cunner /yellowtail decreased from 4423/1000 m to 4278/1000 m3 , while 3
Atlantic mackeret decreased from 1498/1000 m to 3
1070/1000 m . 11akes, the only taxon of the three to increase, increased 210% over last year's total abundance (from 448 to 1513/1000 3m ), a level that was twice that reported in 1986 (751/1000 m3 ). I I
- 3) Overall egg abundances-differed slightly from station to {
station in 1988 (6891/1000 m3 at P2, 7824/1000 m3 at P5 !
and 7248/1000 m3 ,t P7); the percent composition of the
.three dominant taxa combined also differed slightly from station to station (93% at both P2 and P5 and 96% at P7).
Cunner /yellowtail flounder were more abundant at P7 3
(5095/1000 m ) than at either P2.or P5 with a percent 75 f
_ _ _ - _ _ a
l composition at Station P7 of 70%. Hakes were more 3
abundant at PS (1993/1000 m ) than at P2 or P7 and had a percent composition at Station PS of 25%. Atlantic i mackerel, the last of the three dominant taxa was more .
3 abundant at P2 (1449/1000 m ) than at P5 or P7. Percent composition for this species at P2 was 21%.
- 4) Atlantic whiting (#erlucclus billnearts), normally one of ;
the less abundant species in past years, has been slowly i increasing in abundance since 1985-(from 25/1000 m3to ;
3 74/1000 m ).
3
- 5) Overall abundance (annual mean of 1369/1000 m for all !
species combined) of fish larvae in 1988 was almost identical to those observed in 1986 and 1987.(1322/1000 m3 and 1362/1000 3m respectively), and was slightly lower "
than the mean for the twelve year period 1976-1987 3
(1483/1000 m ). Except for the years of 1984 and 1985 i when abundances were 608/1000 m and 699/1000 m respec- >
tively, overall abundances of fish J uvae have remained relatively constant since 1982.
- 6) The two most abundant species of larvae in 1988 were cunner (Tautogolabrus adspersus) and American sand lance (Amwodytes aarericanus),'together accounting for 73% of all larvae collected during the year. Cunner larvae, which ranked second in abundance in 1987, increased 235%
3 (from 237 to 795/1000 m ) in 1988 and alone accounted for 58% of all larvae collected. American sand lance ranked second in abundance in 1988, increasing 168% (from 77 to '
3 206/2000 m ) over the 1987 abundance, but was still lower than the abundance for 1986 (496/2000 m ).
76 i:
y
- 7) Atlantic mackerel, the most abundant species of fish larvae in 1987, ranked tenth in al- dance it. 1988 3
(18/1000 m ) down from a twelve-yee.. high of 666/1000 m3.
All 'other species had abundances within their ranan for the past twelve years.
- 8) Overall larval abundances differed slightly from station ?
to station in 1988 (975/1000 m3 at P2, 1268/1000 m3 at PS, and 1863/10003 m at P7), similar to results in 1987.
Percent composition of the two most abundant taxa coma bined (cunner and sand lance) varied from 66% at Station
, P2 to 71%.nt P7 to 81% at Station PS. ,
3
- 9) Cunner larvae were most abundant at P7 (1123/3000 m )
while American sand lance larvae were most abundant at PS 3
(299/1000 m ). Of the seven other selected species present at all stations: Atlantic mackerel (Scomber scombrus), winter flounder (Pseudopleuronectes
, americanus), Atlantic cod (Gadus mothua), hake (Urophycis sp.), Atlantic herring (Clupea harengus), pollock (Po11achius virens), and yellowtail flounder (Limanda ferruginea), only winter flounder and' hake varied in abundance from station to station. Winter flounder were 3
much more abundant at P7 (132/1000 m ) than at P2 or PS :
3 (20 and 14/1000 m respectively). Hake were more abundant at P2 and P7 (38 and 33/1000 3m respectively) ;
3 than at Station P5 (13/1000 m ). The other selected I species abundances varied little from station to station.
- 10) Species composition for fish eggs and larvas in 1988 was identical to those for previous years with one exception. !
Fourspot flounder (Parallchthys oblongus) eggs, a species i not very common to the inshore areas of Hampton, had an 3
abundance of 39/1000 m on 12 September at Station P?.

6.2 ADULT U NTISH Beach Seines e
- 1. Total-beach seine catch from April to November was 3589 individuals. Atlantic silversides (#en/d/a men /d/a),
nine-spine stick 1chackr vngitlus pung/tlus) and mummichog species (rundulus sp.) were the dominants, comprising 93% of the total catch. This ranking was similar to previous years.
- 2. Total catch was greatest in July (1,184), because of large numbers of nine-spine sticklebacks (1,088). The majority (844) were collected at Station S1. This July peak in nine-spine sticklebacks was comparable with previous years. Total catch was also high in September (907) due to large numbers of Atlantic silversides.
Annual CPUE for winter flounder was at a record low (1.0 ;
per tow) with only 50 individuals collected at the three stations combined, compared with 69 in 1987.
l
- 3. Total number of species was greatest at Station S3 (17) followed by Station S2 (12) and Station S1 (9). Total catch was highest at Station S1 (2,069), and waa due to large catches of Atlantic silversides'and nine-spine ;
sticklebacks. CPUE for Atlantic silversides at a*1 l stations combined was similar to 1987, but CPUE for Atlantic herring (Clupea herengus harengus), Fundulus sp., rainbow smelt (Osmerus mordax) and winter flounder (Pseudopleuronectes amer /canus) was lower than in 1987. j I

Gill Nets
- 1. Total gill net catch (791) was up 10% from 1987. .
Atlantic mackerel (Scomber acombrus), Atlantic herring (Clupea harengus harengus) and pollock (Pollachlus v/rens) comprised 70% of the total catch. Catches of Atlantic mackerel (235) were at their highest levels [
since the study began in 1975. Their percent composition ;
in 1988 was nearly 30% of the total catch compared to an average percent composition of 5% for the years 1976 through 1987. Catches of Atlantic herring, blueback i herring (Alosa sestivalls) and Atlantic whiting
(#erlucclus b/1/nearts) were down slightly from 1987. [
Nearly 60% of the finfish were collected at Station G3 in 1988, but this has varied nearly every year due to the constant movement of pelagic fish.
- 2. CPUE for fish collected in mid-nets in 1988 was higher for Atlantic mackerel, Atlantic whiting and alewives -
(Alosa pseudoharengus). compared to the overall average CPUE for years when mid-nets were fashed (1980-1987).
The species with greatest increase was Atlantic mackerel with a 1988 CPUE of 4.9 per mid-net compared to the seven year average of 0.4 fish per mid-net, lioweve r ,
Atlantic herring CPUE in 1988 (0.6) was substantially lower than the seven-year average (3.5).
- 3. Total number of species was greatest from May through November, when the majority of pelagic fish were in the study area. These results were consistent with previous years. Total number of species (21) was up slightly from 1987 (19), which was the lowest value since the' study began in 1975.

4 Otter Trawls
'1. Overall CPUE for trawls (59 per haul) was 13'4 higher than 1987 ($2.2) and has increased gradually since the record-low set in 1985 (42.5). In most cases, total number of individuals was greatest from summer through early winter. Counts were low in September and October because Station T2 was not sampled. Elevated catches in February and March were due to-large catches of juvenile rainbow smelt (Osmerus mordax).
- 2. Total numbers of yellowtail flounder (4/manda terruginea)
(1,576), rainbow smelt (1,466), longhorn sculpin
(#yoxocephalus octodecerspinosus) (843) and skate species (Raja sp.) (756) accounted for 58% of the total catch for the year. All four of these dominant species incrensed over 1987 levels, and rainbow smelt increated to its highest level since the study began in 1975.
- 3. Station differences were comparable to previous years.
CPUE of yellowtail flounder, cod (Gadus Morhua), hake' specien (Urophycis sp.) and Atlantic whiting (#erlucclus bildnearis) were greater at the deeper offshore Stations T1 and T3, while rainbow smelt and winter flounder CPUE was higher at inshore Station T2.

- 1. Total macrozooplankton abundance (averaged over all stations) in 1988 (3.7 x 10 /1000 m ) was similar to abundances observed in previous years. The highest '
density recorded occurred in 1979 (6.0 x 10 /1000 m ),3 5 3 the lowest occurred in 1980 (2.7 x 10 /1000 m ),
- 2. Total macrozooplankton abundances at Stations P2 (3.6 x 3
10 /1000 m ) and P7 (3.2 x 10 /1000 m ) were lower than those observed at Station PS (4.3 x 10 /1000 m ).
- 3. Peak abundances occurred during the spring and fall of ,
1988 at all three stations. Spring peaks were observed 6
in April at Station P2 (1.9 x 10 /1000 m )3 and P5 (3.1 x 6
10 /1000 m ). Station P7 experienced only a minor peak 5 3 in April (2 " x 10 /1000 m ). At all stations, spring ,
peaks were cominated by Cirripedia (50-92% of total abundance). Fall peaks were observed in September at Station P2 (1.0 x 10 6/1000 m3 ), PS (1.4 x 10 6/1000 m3 )
6 3 and P7 (2.3 x 10 /1000 m ). Fall peaks were dominated by Centropages typicus at all three stations (66-89% of total abundance). The occurrence of a spring and fall' .
period of peak abundance was typical of previous yeats.
- 4. Of the nine major spec oroups, Copepoda (52%), "other taxa" (33%) and Decapoda (12%) accounted for >97% of all macrozooplankton abundance (Stations P2, P5 and P7 ;
combined). Dominant copepods were Centropages typicus (33% of total macrozooplankton abundance) and Calanus finmarchleus (9%). Dominant "other taxa" were Cirripedia (19%), Olkopleurs sp. (9%) Podon sp. (2%), and Evadne sp.
(2%). Dominant decapeIs were Cancer sp. (8%), Eualus 83 r.

pusfolus (3%), Carcinus maenas (1%) and Crangon septemspinosa (1%). Copepoda has ranked first in abundance in previous years except 1979, when "other taxa", usually ranked second'or third, was ranked first due to the dominance of Cirripedia nauplit and cyprids during that year. Decapoda has also ranked second or third in past years.

- 5. In 1988, Calanus //nmarch/cus was more abundant at 0 3 Station PS i9.1 x 10 /1000 m ) than at Stations P2 and P7 4
(3.3 x 10 /1000 m3 and 2.2 x 100/1000 m3 , respectively),
due to higher densities of copepodites at Station PS.
Cancer sp., was most abundant at Station P2 (3.6 x 4 3 10 /1000 m ) with lower densities at Stations PS and P7 (2.4 x 10 /1000 m3 and 2.5 x 104/1000 m3 , respectively).
Neomysis americana was also more abundant at Station P2 j 3 3 (1.6 x 10 /1000'm ) than at Stations P5 and P7 (4.3 x 2 3 3 10 /1000 m and 2.9 x 102 /1000 m , respectively), the-result of considerably higher densities of juveniles at Station P2. Carcinus meenas, unlike Calanus finmarchicus, 3 3 was lower in abundance at Station PS (2.3 x 10 /1000 m )
3 3 relative to Stations P2 and P7 (5.9 x 10 /1000'm and 6.8 3 3 x 10 /2000 m , respectively). Crsngon sep,4mspinosa, i
like Carcinus maeru, was lower in abundance over all i lifestages at Station P5 (1.4 x 103 /1000 m 3
) relative to Stations P2 (3;2 x 10 3/1000 m3 ) and P7 (2.8 x 10 3/1000 m3 ). I i

6.4 BIVALVE 1ARVAE
- 1. Bivalve larvae species composition in 1988 was similar to -
that observed in previous years at Stations P2 and P7. j The dominant spocies was #rtflus edu11e (39% and 54% of I all umboned larvae at Stations P2 and P7,x respectiwis). I This species was especially abundant from late May to !
Inte July. Three other taxa ranksd as secondary domi-nants in 1988: #eteranomia squacula (24% at P2, 14% at ;
P7), Nisto11a sp..(15% at P2, 14% at P7) and #odlolus mod /olus (8% at P2, 10% at P7). #eteranonla squamula was !
present April through October, though not on all dates, with peak abundances occurring sporadically from mid-June through early October. #latella sp. was also present during the period sampled, April through October, peaking in abundance mid-Hay through mid-July. Mod /olus modiolus was observed occasionally from April through mid-Hay and was common from late hay through October, with peak abundances occurring in late June and early October. All .
other identified bivalve taxa constituted 8% and P; of the larval assemblages at Stations P2'and P7, respec-tively. Unidentified bivalve larvae accounted for 6% and 4% of the umboned larvae at Stations P2 and P7, respec- ;
tively. Overall abnndances of bivalve larvae were within ranges found in past years.
- 2. Station P1 (added to the program-in 1986) and S etion P5 '
(added to the program in 1988) were similar to Stations P2 and P7 in terms of epecies composition. Stations P1 and P5, like Stations P2 and P7, were dominated by 1 Nytilus edulis (P1-40%, P5-48%) with #eteranomia squacula (P1-11%, PS-17%), N. fate 11a sp. (P1-13%, P5-11%) 'and Modlolus modiolus (P1-25%, P5-11%) as secondary domi-nants. Peak abundances occurred at approximately at the ,
same time at'all four stations.

-10 larvae /m ) and lowest at Station P2 (3.8 x 10 lar-3 vae/m ). Mean abundances of Myt/ Jus edu1/s (4.2 x 10 larvae /m3 ) Neteranom/a squamula (1.1 x 103 larvas /m3 ) and
' Rfacc11a sp. (1.1 x 10 1ervae/m3 ) were highest at Station P7, whila #od/oluo modfolus (1.5 k 103larvae /m 3) was most abundant at Station Pl. Other bivalve species were present at all stations in low numbers.
- 4. Nya arenaria constituted less than 1% of the. total bivalve larvae assemblage at Stations PS and P7, and 1.5%
and 1.7% of the total bivalve larvae assemblage at Stations P1 and P2, respectively. Yearly means ranged from 23 (Station PS) to 90 larvae /m3 (Station P1). This was cottarable to most previous years, though much lower then the yearly mean of 255 larvae /m3 observed at Stetton P2 in 1982. In 1983, an early summer peek in density was 6 observed at all four stations (peak density of 250 3
larvae /m at Station P2). Similar early summer peaks have beta observed in the past (1978-1981, 1984, 1986- ,
1987). A late summer to early fall paak was observed at all stations in September and October, with the highest density observed at Station P1 (P1-1199 larvae /m , P2-965 ,
3 larvae /m , P5-208 larvae /m3 , P7 420 larvae /n ). IIIstori-cally, the peak deuity observed at Station P2 in 1968 ranked fourth Jn comparisos with maximum densitio of each of the previous ten years (1978-1987).
I
- 5. The most abundant species of bivalve larvae collected in' '
1988 was Nytilus edulls, as in previous years. Nytilus edulfs comprised 40% of the total bivalve larvae assem-blage at Station P1, 39% at P2, 48% at PS and 54% at P7.

I Peak abundances occurred at all stations between mid June and late-July, with the greatest density at Station P7 i 3
(63,987 larvae /m ). After mid July, larval densities 3
decreased and were below 1,000 larvae /m at all stations by 1 August. Densities remained low through the end of the sampling season with a minor fall peak occurring only 3 '
at Station P1 (1433 larvac/m ) in early October, 111stori-cally, the observed peak density at Station P1 in 1988 ,
(27,110 larvae /m3 ) ranks seventh in comparison with the ,

- 1) Hean abundance of lobster larvae (for larval stages I-IV and Stations P2 and P7 combined) in 1988 was 48% lower than in 1987 (0.74/1000 m2 and 1.43/1000 m respec-tively). The 1988 mean abundance was 37% lower than the 2
mean abundance (1.18/1000 m ) for the previous six year period when both stations were sampled (1982-1987). When Station PS is combined with P2 and P7, the mean abttndance in 1988 increases to 0.951arvae per thousand a:quaro meters. Mean abundance at Station P2 (0.84/1000 m ) was slightly lower in 1988 than the abundances for both 1987 2
(0.92/1000 m ) and the mean (0.90/1000 m ) for the previous ten years (1978-1987) when P2 has been sampled.
e Abundance at P2 in 1988 was identical to those values reported for 1986 and 1985. Hean abundance at Station P7 2
was 66% lower in 1988 than in 1987 (0.65/1000 m and 1.94/1000 m , respectively) and was 57% lower than the mean (1.5/1000 m ) for the previous six years when P7 has been sampled. Abundance at P7 was lower in 1988 than in any of the previous six years at that station. !
- 2) All stages (I-IV) of lobster larvae were collected in l 1988 as in 1979, 1981 and 1983-1985. Stage IV larvae -
predominated at all three stations in 1988, accounting .
for 70% of all larvae collected. Stage IV larvae also predominated in 1978, 1981, 1982 and 1984-1987.
- 3) Larval abundances for all stations combined exhibited two-peaks in 1988. The first peak occurred on 1 August when-the abundance was 8.00 larvas per thousand square meters.
This peak colucided with large abundances of Stage I and I
Stage IV larvae. The second peak occurred on 23 August s
(4.21/1000 m ) when large numbers of Stage III and Stage 91
. -l
i IV larvae were present. Ilistorically, peak abundance l usually occurred in either July (1979-1983 and 1987) or in August (1978, 1984-1986). l
- 4) I!istorically, Station P7 has shown higher abundances than Station P2 consjstently during the six year period both ;
stations were sampled. In 1988, however, the abundance ;
at P2 was 23% higher than the abundance at 17. This difference can be accounted for by the large difference in the abundances for Stage I larvae found at each 2
station (0.17/1000 m at P2 and 0.03/1000 m at P7) and j the lack of Stage III larvae at Station P7. Abundance at Station P5 was 60% higher than at Station P2, and 103%
higher than at Station P7. This difference can be accounted int by the large abundances for all stages (1-IV) of lobster larvae found at Station P5 on 1 August (15.33/1000 m2 ),
l l
l 5) In 1988 lobster larvae were caught on 36% of the sampling dates at Station P2, 50% of the sampling dates at Station '
PS, 45% of the sampling dates at Station P7, and 60% of the sampling dates for all stations combined.

ledge", Site D - Mean how Water "Chondrus crispus zone") at Stations B1MSL and B5MSL were monitored for seasonal and spatial differences. The following observa- !
tions were made for selected intertidal fauna:
Site B - Fucold ledge - Ilistorically, a greater n' umber of species occurred at this site, both stations, than at either the bare ledge site or Chondrus zone. At Station B1MSL two macrof aunal species have consistently occurred during all three sample periods, Mytilidae and Nucella lapillus. Mytilidae percent frequency of occurrence during 1988 was lower than past years. N. Japillus has consistently occurred most frequently during July. l llistorically, at Station B5MSL, Balanus sp and Littorina littorea have been the most frequently occurring species j
-l recorded, During 1988, these species along with three others occurred at approximately the same average fre-

period. Balanus sp. had set during April and persisted through July, Littorina saxatills occurred only in April' and Mytilidae occurred only in December. The percent ,
frequency of occurrence overall at thia site for 1988 was a marked reduction from the values for 1987.
At Station B5MSL, the two primary residents were Balanus sp. and the gastropod Littorina saxatills with percent frequencies of occurrence in both cases ;
consistent with past years. Mytilidae and the gastropod '
Littorina 11ttorea followed a general historical trend of ;
increasing percent frequency of occurrence from April to December; however, the actual values for 4. littoros in 1988 were noticeably reduced compared to past years.
Site D - Chondrus crispus zone - This site was reported for the first time in 1987. Nucella lapillus occurred most frequently at Station B1MSL followed closely by Mytilidae. The actual values for both were consistent with those from 1987. At Station B5MSL Nucella lapillus was also the most frequently occurring macrofaunal t species. Littorina littorea and Mytilidae were quite abundant in 1988, consistent with 1987 values.
Tonicella sp. and Lacuna vincta were both recorded for the first time since the inception of the intertidal non-destructive program.

.c 6.8 MARINE MACROALGAE
- 1. A total of 77 unique algal taxa were identified at all subtidal and intertidal stations in 1988; 52 intertidal and 69 subtidal species were encountered. The community composition consisted of 18% Chlorophyta, 26% Phaeophyta, and $6% Rhodophyta. At all subtidal stations in August, 46 species were noted while 59 species were encountered-at intertidal stations. The community composition for
)
August was similar to that for the entire year. At selected subtidal (B17, B19, B31, B35) and intertidal stations (B1MLW, B5MLW) sampled triannually, 33 and 36 species were identified, respectively. These numbers are consistent with findings throughout the past years. The
]
red a)ga Bonnemaisonla haml/ era was collected for the '
first time in 1986 and was found in small amounts in 1987 and 1988.
- 2. At selected subtidal stations sampled in 1988, the highes,t overall mean dry-weight biomass (993.11 g/m2 )
occurred in August while the lowest overall mean dry-weight biomass (540.82 g/m ) was observed in November.
The highest overall mean dry-weight biomass values for 1984-1987 were also observed in August. Historically, the lowest overall mean dry-weight biomass occurred in either May or November.
- 3. A comparison of selected subtidal stations showed the highest mean dry-weight biomass (1619.17 g/m ) was recorded at Station B35 in August. This represents a change from past years (1984 - 1987) in which the' highest mean dry-weight biomass was found at Station B17 in August. In 1988, the lowest mean dry-weight biomass (297.76 g/m ) was recorded at Station B19 in August.
103 a,as
l The lowest mean dry-weight bion ssa has historically been recorded at Station B19; however, there has been no trend among years as far as sample period is concerned.
- 4. At intertidal Stations B1MLW and B5MLW (combined) the highest overall mean dry-weight biomass value occurred in August (1692.07 g/m ) and lowest occurred in November (893.63 g/m ). The highest overall mean dry-weight biomass in 1987 was 918.97 g/m (in August) and 731.43 g/m (in May) was the lowest. The 1988 highest overall mean dry-weight biomass value represented an 84% increase over 1987; however, these values fell within the range of previous years.
I
- 5. Intertidally, the highest and lowest mean dry-weight biomass values for 1988 were observed at Station B1MLW; 1828.84 g/m in August and 849.76 g/m in November.
There has been no consistent trend throughout previous years.
- 6. The mean dry-weight biomass at subtidal stations in the more spatially extensive annual (August) survey was highest at Station B35 (1619.17 g/m ) and lowest at Station B34 (57.15 g/m ). At intertidal Stations B1MLW and B5MLW in August, the mean dry-weight biomass values were 1828.84 g/m and 1555.30 g/m2 , representing increases of 87% and 81% respectively over 1987 data. In both cases the 1988 data was consistent with values observed in years previous to 1987.
104
- 7. Chondrus crispus and Phyllophort spp. had the highest and second highest, respectively, mean dry-weight biomass at subtidal stations in 1988. As in past years, a general trend of decreasing dry-weight biomass with increasing =
depth was observed. Chondrus crispus was the dominant -
algal species at Station BlMLW and Corallina o//lclonalls 2 had the second highest mean dry-weight biomass.
C. crispus was the dominant algal species at Station B5MhW followed by Mastocarpus stellatus. F

- 8. In the 1988 subtidal transect survey, Laminarla ,
saccharina was most abundant at shallow subtidal Stations B17 and B35. Laminarla digitata was common at Stations B17 and B35; however, it was most abundant at the mid-depth subtidal Stations 819 and B31. Agsrum cr/brosum -
was present only at deeper Stations B19 and B31. Alarla a esculenta was the least abundant of the kelps, present only at Station B31 and during the April sampling period at Station B ;. These results were consistent with the findings in 1986 and 1987.
- 9. Based on frequency of occurrence, dominant "understory" algae in the subtidal transect surveys showed depth-related differenceu. Consistent with previous years, l
Chondrus crispus was most commnn at the shallow subtidal Stations B17 and B35. The perccat frequency of Phyllophora spp. and Ptilota serrata was highest at the mid-depth Station B19.
- 10. Three fixed-quadrat samples 'one " Bare" rock, one "Fucold" algae covered and one Chondrus crispus-covered) in the mean sea level zone (MSL) were monitored for seasonal and spatial differences. The following observa-tions were made:
105
, . ~. -
Spring (April) - The total number of " ephemeral" macro-algal species observed was high, with most species present at Station B1MSL. Of the dominant perennial species, Tucus resiculosis had the highest percent frequency at both Stations B1MSL and B5MSL, Site B.
Site C had 100% frequency of juvenile Fucales, identified as Tucus sp. No flora appeared at Station B1MSL, Site C.
The highest percent frequency of Nestocarpus stellatus occurred at both Stations BlHSL and B5MSL, Site D.
Summer (July) - The number and abundance of " ephemeral" algal species were substantially more in July in compari-son to April with the exception of Site C. The overall abundance of the dominant perennial algal species was higher at Station B5MSL. Abundance of Fucus Fes/culosis was similar to that observed in April at both Stations B1MSL and B5MSL, Site B. T. vesiculosis did not appear at Site C at either station. Juvenile Fucales, identi-fled as Tucus sp., occurred only at Station B5MSL, Site C (100 per cent frequency). Tucus distichus ssp. edentatus was present for the third year (1986 - 1988) at Station B1MSL.
Late Fall (December) - There were three " ephemeral" species recorded in December, two at Station B1MSL and one at Station B5MSL. The dominant perennial alga Tucus resiculosis did not appear at either station in December.
However, Tucus distichus ssp. edentatus did occur at both Stations B1MSL and B5MSL. Tucus sp. was observed in December at both Stations B1MSL and B5MSL, Site C.
- 11. Fucold algal species were examined during the intertidal transect study in the mean sea level (MSL) zone. Asco-phyllum nodosum abundance was greatest at both stations B1MSL and B5MSL during December, with 27% and 70%,

and B5MSL (38%). Focua distichus esp. edentatus was observed at Station B1MSL during all three sample periods and at Station B5MSL during July.
- 12. During'.the July sampling period,'the total percent -l
, frequency occurrence of fucold epiphytes showed a marked '

highest mean abundance of non-colonial species in 1987 (13,173 in July at Station B31). The highest overall--
mean abundance occurred in 1981, when densities reached ,
41,369 in September at Station B19, !
1 In July the total number of different ftunal species q (colonial and non-colonial) was 20. The combined number of faunal species in July, over all stations, has ranged from 9 to 27 over the study years 1982-1984,,.1986,L1987 -

stations. Obella geniculata settled only in July, unlike Campanularia spp.:which first appeared in June and occurred through October. Tubularla sp. settled in July, peaked in August, and appeared through December over all' stations.- Bac111ariophyceae represented the highest overall frequency of algae-on the panels and was present throughout most of the year at all stations. Petalonia I.iscia war present on ST panels only in the months of -
June, July and August, and was followed by Pflayella littoralis, which was present on1'y during September for most stations. Polysiphonia urcoolata persisted in settlement throughout most of the year. This particular algal species first appeared in January and. February, and occurred again May through October, peaking.in' August.
Juvenile brown algae (Ectocarpales spp.) were present in July and August, with occurrences again in October.and November; August was the peak month at most stations..
M tilidae, the dominant.non-colonial taxon, were most numerous in July es were #datella sp. (except at-Station-B04 where the peak was in June). ' Juvenile amphipods were generally found to be most. numerous in August (except at Station B04 where the peak was in June) Jassa falcata first settled in February and occurred again in April, May and. July through Cecember, with peak abundance occurring in the fall of the year;at most stations.
Ischyrocerus anqufpes occurred during the months of May through December. Anemia sp. were present in January-and February, again in April, and in July through December.:
Nudibranchia, particulwrly Coryphella ruffbranchlalis, were present in January through Desember, with the exception of the months of March, April and' June.. Nerels sp. occurred in July through September, and again in November at most stations.

--in 1988', with a total count of 58,300 individual-animals.
Results from Stations B19 and B31 reflected a substantial
' increase in the settlement'of Mytilidae when compared to !
the 1987-counts for these stations, while Sta.tions B04.
and B34 showed a decrease. In addition, a notable 'i decrease 'in Jassa falcata, Riatella sp. , and' Anomia sp. -l occurred. In general, the relative abundance of these l
three taxa parhilels that of previous years when panels were submerged for one year (1982, 1983,~1984 ;and:1987).

the previous year. In August, a decrease in mean size '
was' observed, likely.the result of ovigerous females 1 present earlier,.which vould have produced. juveniles by summer. Mean size decreased more noticeably in November at Station B17 than at Station B35. Mean size at each !
station and for each sample period.was consistently. ,
higher than in 1987 except at: Station B17 in November '
where mean size decreased from August. The percentage of J. falcata carrying eggs or brood was equal to or greater than in 1987 and 1986, but not as high as in 1985.

- in density. .The overs 11 1988 mean spat density-(3/ft ) j
- was the second-lowest since 1974._(2/ft ); 1976 had th'e highest mean density,with 762 #pa-per square foot.
Coincident with the low numbers of spat'were high numbers of the principle non-human predator Carcinus'moonus (section 6.11). !

mean density of juvenile,and adult #ra arenarla, ,
0.52/ft , frem Flats-l', 2 and 4 combined was twice that I of 1987. Flat.2'showed only a slight decrease (8%),
~
while Flats 1 and-4 exhibited two and three-fold '!
increases. Historically, Flat i has shown the highest densities'of Nya since 1982 but ranked second to Flat 4 in 1987 and 1988. The largest recorded populations of the soft-shell clam in the Hampton Harbor surveys were observed in.1979-1981 and have generally declined since that period.
- 3. The overall standing crop estimates'of Nya arenaria
(> 25 cm) for 1988 were 28% higher than those for 1987, attributable to the near five-fold increase in 2-4 year !

Values were lowest in early January and early August (0.25 pg/l and 0.35 pg/l, respectivelyT Concen-trations in 1987 peaked in early October and early April (1.49 pg/l and 1.4 pg/l, respectively) and were at minima in late March and early August (0.17 pg/E and 0.19 pg/l, respectively). Comparison of concentrations between stations showed little difference except on peck sample dates. In early Novembei concentrations at .
Station P7 were less than half those found at Stations P2 and P5 and in early March concentrations at Station P2 were substantially lower than at P5 and P7.
