SUMMARY
This progress report presents data from field and laboratory work during the period February 1 to April 30,1984. Also included are the results of observations on gonad development in samples collected in January, February and March,1984.
All field work during this quarter was carried out by GPU Nuclear personnel.
Tcmperature, salinity, dissolved oxygen and pH were measured and recorded at each of the 20 stations during the three periods of exposure panel exchange.
The exposure panel exchange in March,1984, was a week later than scheduled due to weather conditions. Panels installed in March were pre-soaked for three weeks instead of the standard two weeks.
A few timnoria tunnels were found in the long-term exposure panels removed fr:m the station at the mouth of Oyster Creek in February,1984. Two of the tunnels were occupied and five of the seven tunnels were made by juveniles.
No unusual aspects in the biology of the teredinids collected during the present r: porting period were observed. Gonadal tissues from the January collections showed mostly spent or early active stages. Those studied from the February and March c:llections showed mostly early active stages, as gonad development proceeds toward the spring and early summer spawning periods.
1 PROGRESS REPORT FOR THE THIRTY-SIXTH QUARTER on STUDY OF WOODBORER POPULATIONS IN RELATION TO THE OYSTER CREEK NUCLEAR GENERATING STATION to GPU NUCLEAR CORPORATION May 31,1984 by R ht E. Hillman and C.I. Belmore REPORT NO.15235 February 1,1984 to April 30,1984 from BATTELLE New England Marine Research Laboratory Duxbury, Massachusetts 02332 INTRODUCTION Battelle's New England Marine Research Laboratory is ccnducting an investigation to determine whether the Oyster Creek Nuclear Generating Station is offecting the resident marine borer population in Oyster Creek to the extent that that population is contributing significantly to marine borer-caused damage in Barnegat Bay.
A description of the program and procedures used may be found in the eighth cnnual report titled, " Study of Woodborer Populations in Relation to the Oyster Creek Generating Station", dated February 15,1984.
This report presents data for the thirty-sixth quarterly period from February 1 to Aprl! 30, 1984.
2 PROCEDURES AND INTERIM DATA Exposure panels The long-term and short-term exposure panels were retrieved and replaced with new untreated pre-soaked (for two weeks) panels at the 20 exposure sites in Barnegat Bay and adjacent waters (Figure 1) during the periods of February 13-14, March 19-20, and April 16-17,1984. Long-term and short-term panels at all stations were retrieved and r;placed by personnel from GPU's Oyster Creek Nuclear Generating Station.
Exposure panels installed in March,1984 were pre-soaked for three (3) weeks due to postponement of the panel exchange for one week because of weather conditions.
Table 1 describes the geographical locations of the exposure sites. Data from the laboratory examination of the panels are presented in Tables 2 through 5.
P-ter Quality Salinity, water temperature, dissolved oxygen and pH were taken at each site by the GPU Nuclear field team. Results for February, March, and April,1984 are pr:sented in Tables 6 through 8.
Teredinid Gonadal Development Studies Table 9 shows the gonad condition of teredinid borers collected in January, ,
FIbruary, and March,1984. Included are results from panels exposed for periods ranging fr:m 6 to 12 months.
