The Eastern Bering Sea Shelf The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder easternberingsea00hood Year: 1981 Figure Location of neuston and oceanographic sampling stations occupied in the soutiieast Bering Sea, April 10-29, 1978. The upper figure shows the stations in Phase 1, April 10-20, and the lower in Phase 2, April 21-29. A total of 145 neuston net hauls were carried out at 157 hydrographic stations. Stations were selected over almost the entire area of the continental shelf and slope and partly over the deep sea along transects across the area from southwest to northeast. Spacing of two consecutive stations was approximately 6-28 km. The shelf deeper than 100 m is designated as outer shelf, and the shelf shallower than 100 m as inner shelf. Duplicate occupations of the same, or nearly the same, positions were made after 5-10 days to record the changes in hydrographic conditions and distribu- tional patterns and abundance of the eggs. Thus, the sampling season was divided into two phases: the first was 10-20 April and the second 21-29 April. A total of 64 stations were occupied in Phase 1, and 93 stations in Phase 2. Water temperature and salinity were measured at hydrographic stations. For geographic comparison of hydrographic conditions, the study area was tenta- tively subdivided into four areas: north, northwest, southeast, and southwest. The extent of each area varied in the two phases. For each area, mean tem- perature and salinity values were computed for the surface, 30-m, and bottom layers. At stations where the depth was more than 200 m, the value at a depth of 200 m was used as the bottom layer. Sampling gear Egg collection was made with a neuston net called 'Hopping Boy' (Komaki and Morioka 1975). The structure of this net resembled that of a single-unit net invented by Zaitsev (1964): it consisted of a wooden frame with two stabilizing bars and a net. The frame was rectangular, m
