Correlation of late Cenozoic marine deposits in Chukotka, northeastern Siberia and western Alaska

Only the marine fossils along the coasts which surround the Bering Sea can be correlated. The Krestovskaya sediments of the Chukotski region are probably the equivalent of the Kotsebue transgressive sediments in Alaska, and represent a maximum for Pleistocene water temperatures. Yet the sediments representing the minimum water temperature in mid-Pleistocene times do exhibit certain distinctive warm-water features.
