. The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder. Oceanography Bering 602 Fisheries oceanography accompany adults en route to spawning grounds. Salmon occur throughout the southern part of the shelf area; king salmon reach the Yukon River mouth, and the extensive sockeye salmon runs reach Bristol Bay before the end of the month. July Air temperatures approach 10 C and sea-surface temperatures of 10-12 C occur in the Gulf of Anadyr, 3-5 C at the west side and 5-7 C at the east side of Bering Strait, 14-16 C in inner Norton Sound, 10-12 C southward along the coast to Unimak Pass, and 5-7 C in midshelf areas seaward over the basin. Bottom temperatures in the midshelf area from the Gulf of Anadyr to the Alaska Peninsula range from —1 to 1 C; in Bering Strait, 1-2 C; in inner Norton Sound, 5-9 C; along the coast from Norton Sound to Unimak Pass, 7-10 C; and along the shelf edge, 2-4 C. Off- shore dilution due to river discharges along the Alaskan coast continues and minimum salinity values occur in outer Bristol Bay (28*-*/oo). Herring spawn along the coast northward of Norton Sound to Kotzebue Sound; no information is available on the Gulf of Anadyr stocks (Fig. 36-6). Yellowfin sole spawning begins northwest and south- east of Nunivak Island, the two stocks apparently remaining separated; however, both spawning areas remain inshore of the mid-shelf cold front in an area of general northerly flow. Pollock distribution. Figure 36-6. Schematic diagram of July distribution of halibut, herring, pollock, and yellowfin sole. (Solid dia- monds indicate spawning areas; long dashes indicate prob- able extension of shelf range; short dashes indicate juvenile distribution, where known or different from adults.) Salmon occur throughout the shelf area. remains the same as the previous month, adults generally seaward of the 50-m isobath but juvenile pollock and herring remaining in inshore areas.
