Abstract : The data on the composition and distribution of the bottom fauna in the western Bering Sea were received in 1950-1952. During that period 256 stations were occupied. One hundred seventy-three quantitative samples of the bottom fauna were taken with large bottom-sampler 'Ocean-50' and Petersen grab and 64 samples were gathered with Sigsbye trawl. Forty-six of the stations were occupied at the depths exceeding 1000m and 38 of them--at depths exceeding 2000m. Eighteen communities of the bottom fauna were established in western Bering Sea. True oceanic deep-sea species are dominant in the abyssal bottom-fauna communities of the western Bering Sea. Some species living presumably on the slope of the shelf are the leading forms of bathyal communities. A great many arctic-circumpolar, arctic-boreal, and north-boreal Pacific species of the bottom fauna are part of the composition of the shallow-water communities of the western Bering Sea. (Author)
