SUMMARY

I This progress report presents data from field and laboratory work during the period November 1,1984 to January 31, 1985. Also included are the results of observations on gonad development in samples collected in October, November, and December,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.

The long-term exposure panel from Station 1, which was scheduled for removal in January,1985 was taken out of the water in November,1984 due to the deteriorating condition of the panel.

I One empty Limnoria tunnel was found in the long-term exposure panel removed from Station 10A in December,1984. This was the first time that any Limnoria s

tunnels have been recorded from the exposure panels submerged at this station.

With the exception of Station No.1, where the teredinid attack continues to be very heavy, the borer attack at the other stations has been light or absent in the exposure panels examined during the past quarter.

Most gonads from the October, November and December samples were in the spent stage, although some gonads showed signs of early activity. This activity was probably begun in the late summer and early fall, and ceased as water temperatures fell through October, November and December, i

I E I PROGRESS REPORT FOR THE THIRTY-NINTH QUARTER on STUDY OF WOODBORER POPULATIONS IN RELATION TO THE OYSTER CREEK NUCLEAR GENERATING STATION to GPU NUCLEAR CORPORATION February 28,1985 by Robert E. Hillman and CJ. Belmore REPORT NO.15274 November 1,1984 to January 31,1985 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 Oyster Creek Nuclear 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 eighth annual report titled, " Study of Woodborer Populations in Relation to the Oyster Creek I Generating Station", dated May 15,1984.

This report presents data for the thirty-ninth quarterly period from November 1,1984 to January 31,1985.

I

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 12-13, December 10-11,1984 and January 14-15, 1985. Long-term and short-term panels at all stations were retrieved and replaced by personnel from GPU's 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 I Salinity, water temperature, dissolved oxygen and pH were taken at each site by the GPU Nuclear field team. Results for November, December,1984 and January, 1985 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,1984. Included are results from panels expcsed for periods ranging from 4 to 12 months.
