1 Executive Summary This progress report presents data from field and laboratory work during the period November 21,1982 to January 20,1983.

All field work during this quarter was carried out by GPU personnel.

Temperature, salinity, dissolved oxygen and pH were measured and recorded at each of the 20 stations during the two periods of exposure panel exchange except in December,1982 when there was an equipment malfunction at some of the stations (see Table 5).

The laboratory analysis of the exposure panels shows the species Teredo bartschi to be absent from any of the exposure panels in Barnegat Bay, New Jersey during the 1982 settling season.

Teredinidae were breeding and settling during the month of November this year at Station 1, which is a month later in the year than usual at this location.

Limnoria were present at Station 1 through 4A as in previous years. Juveniles ,

were observed in panels removed from two stations in December,1982 and from three stations in January,1933. Last year juveniles were only recorded from one station in December and none in January.

The gonads of most specimens were found to be in the partially spawned to spent stage during November and December, which is typical for this time of year.

2 PROGRESS REPORT FOR THE THIRTY-FIRST QUARTER on STUDY OF WOODBORER POPULATIONS IN RELATION TO THE OYSTER CREEK GENERATING STATION to GPU NUCLEAR CORPORATION FEBRUARY 28,1933 by Robert E. Hillman and C.I. Belmore REPORT NO.15173 November 21,1982 to January 20,1983 from BATTELLE New England Marine Research Laboratory Duxbury, Massachur.etts 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 borcr-caused damage in Barnegat Bay.

A description of the progam and procedures used may be found in the sixth annual report titled, " Study of Woodt:rer Populations in Relation to the Oyster Creek Generating Station," dated March 15,1932.

This report presents data for the thirty-first quarterly period from November 21,19S2 to January 20,1983.

3 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 December 6-7,1982 and January 3-4, 1983. Long-term and short-term panels at all stations were retrieved and replaced by personnel from GPU's Oyster Creek Nuclear Generating Station.

Table i describes the geographical locations of the exposure sites. The data for the laboratory examination of the panels are presented in Tables 2 through 4.

Water Quality Salinity, water temperature, dissolved oxygen and pH were taken at each site by the GPU field team. The results for December,1932 and January,1933 are presented in Tables 5 and 6.

Teredinid Gonadal Development Studies Table 7 shows the gonad condition of the teredinid borers collected in November and December,1982. Included are results from panels exposed for periods ranging from 6 to 12 months.
