. The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder . 31.5 32.0 33.0 33.5 Salinity %o Figure 58-2. Temperature and salinity and phospiiate- salinity envelopes in Zhemchug Canyon area of the Bering Sea in July 1969 (Oshoro Maru cruise 32, Faculty of Fisheries, Hokkaido University 1970). Individual envelopes enclose all station data in 0- to 150-m water columns (0 to the bottom where the bottom is less than 150 m) at indi- cated stations: deep Bering Sea, Stations 23, 78, 84, 88, 94, 96, 106, 114; outer-shelf domain, Stations 87, 91, 92, 108, 109, 110; mid-shelf domain. Stations 30, 36. over the outer-shelf domain and 32.70-33.32^/00 over the deep Bering Sea) fall in almost the same range as those observed during the summer of 1978, and the two water masses are clearly distinct with respect to the distribution of phosphate. We there- fore conclude that the zonation of nutrients is a general feature of the eastern Bering Sea in summer. Unfortunately, nitrate and silicic acid data were not collected in 1969. At several stations between the outer-shelf domain and the deep Bering Sea some mixed structures, similar to those observed at Station 9 of the 1978 summer cruise of R/V Hakuho Maru were also found (Fig. 58-3). Temperature and salinity cross sections (not reproduced here) clearly show the intrusion of the shelf water into the deep Bering Sea or the intrusion of the deep Bering Sea water into the outer-shelf domain in this transition area. The relationship between atoms of nitrate-N and phosphate-P is approximated by a straight line with a slope of about 15:1 over extended areas of the eastern Bering Sea in summer (Fig. 58-4). This relationship is similar to the global average in other marine water (Broecker 1974). The line intercepts the X-axis, indicating that phosphate is in excess of nitrate by 0.45-0.60 /ig at/I. Below the seasonal thermocline, nitrate-N/phosphate-P corrected for 176° 59 - 58° -
