During the reported period, the efforts of the Israeli investigators were directed toward carrying out multidisciplinary surveys of the Israeli continental shelf; tracking data from the surveys conducted during the previous period; and at optimization of design and further surveys. With the replacement of problem-ridden. old Bio Sonics echo sounder with a reconditioned Model 102 Dual- Beam Echo sounder. two surveys were successfully conducted on 14-18 May and 17-20.September 1995. On both cruises acoustic surveys of pelagic fish stock and concurrent sampling statistics to measure environmental parameters were made on board the R/V Shikmona by the Israeli scientific team in collaboration with Mr. Gert van Dijken of Texas A&M University. The acoustic surveys consisted of 19 transects and 29 concurrent sampling stations. At these stations. samples to study the concentrations of zooplankton, phytoplankton standing crop, and inorganic nutrients were collected. Also at these stations, salinity and temperature were measured.
