A jointly supported program between the Bureau of Land Management and the U. S. Geological Survey, Pacific-Arctic Branch of Marine Geology was undertaken in the Southern Bering Sea with funds managed by the Outer Continental Shelf Environmental Assessment Program (OCSEAP) Office. This report provides data from analyses that were performed on Miocene and Pliocene rocks and sediments taken from dredge hauls along the continental slope, DSDP holes (184B and 185) along the outer part of the continental slope and Umnak Plateau, and the Sandy River Well on the Alaska Peninsula (figs. 1 and 2). Vallier and others (1979) incorporated these data in a discussion of Neogene sedimentation in the southern Bering Sea.
