SUMMARY
This progress report presents data from field and laboratory work during the period October 21,1983 to January 3. ,1984.
All field work during this quarter was carried out by GPU Nuclear personnel.
Temperature, salinity, dissolved oxygen and pH were measured and recorded at each of
{
the 20 stations during the three periods of exposure panel exchange.
Exposure panel racks at Stations 1 and 7 were moved to different locations on the same docks. Station 8 and 9 were relocated to other sites. Station 3 was moved about 2,000 feet further away from the generating plant and Station 9 was moved about 2,000 feet closer to the plant.
No Teredo bartschi were found in any of the exposure panels examined from Barnegat Bay during 1983.
No unusual patterns of gonad development were noted for the months of October, November, and December,1983.

PROGRESS REPORT FOR THE THIRTY-FIFTH QUARTER on STUDY OF WOODBORER POPULATIONS j IN RELATION TO THE OYSTER CREEK GENERATING STATION to f GPU NUCLEAR CORPORATION February 29,1984 by Robert E. Hillman and C.I. Belmore l REPORT NO.15220 October 21,1983 to January 31,1984 from BATTELLE New England Marine Research Laboratory Duxbury, Massachusetts 02332 INTRODUCTION Battelle's New England Marine Research Laboratory is conducting an investigation to determine whether the generating station is affecting 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 seventh annual report titled, " Study of Woodbcrer Populations in Relation to the Oyster Creek Generating Station", dated May 15, 1983.
This report presents data for the thirty-fif th quarterly period from October 21,1983 to January 31,1984.

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 November 7-8, December 5-6, 1983, and January 9-10, 1984. Long-term and short-term panels at all stations were retrieved and replaced by personnel from GPU's Oyster Creek Nuclear Generating Station.
I At the time of the November,1983 panel exchange period, the exposure panel rack at Station 1 was moved to the opposite side of the bulkhead and about 40 feet closer to shore. The exposure panel rack at Station 7 was re19cated to the end of the same dock into deeper water. Station 8 was changed to a company-owned dock about 2,000 feet nearer to the mouth of Oyster Creek. Also, Station 9 was changed to company-owned property about 2000 feet closer to the Oyster Creek Nuclear Generating Station.
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.
Water Quality Salinity, water temperature, dissolved oxygen and pH were taken at each site by the GPU Nuclear field team. Results wr November, December, 1983, and January,1984 are presented in Tables 6 through 8.
Teredinid Gonadal Development Studies Table 9 shows the gonad condition of teredinid borers collected in October, November, and December,1983. Included are results from panels exposed for periods ranging from 6 to 12 months. No unusual patterns of development were observed.
