The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder . easternberingsea00hood Year: 1981 Northern fur seals 851 1883-97. Fig. 52-3 is a modification of Townsend's map giving harvest information from the Bering Sea and vicinity. Each circle indicates the location of a vessel for one day's sealing. The 96-km limit (indi- cated by a dotted line around the Pribilof Islands) resulted from regulations which followed an 1892 treaty between the United States and Great Britain (representing Canada). Townsend's chart indicated that from July through September fur seals were abundant within a semicircle as far as 250-350 km northwest to southeast of the Pribilof Islands. This area included deep water southeast of the 200-m depth contour and extended southeast to the Aleu- tian Islands. Fewer vessels operated directly north or east of the Pribilof Islands. These sealing records are probably a good representation of fur seal distri- bution outside the 96-km closed area, because seal- ing was profitable and the sealers would probably have found other areas of concentration if they had existed.
