During or just after each storm (reinitiation of wave action), the consolidated front is again broken up into small floes. The uni- formity of floe size north of the fringe suggests some unknown structural characteristics of the ice itself or of waves dampened by their first encounters with ice of the narrow fringe zone. Beyond Bristol Bay, floe size tends to be uniform from east to west within the front, although the thickness and extent of deformation are different. Thickness and deformation increase westward, indicating the increased incorporation into the front of ice from more northern areas of the Bering Sea. In the regions south of Nunivak Island and in Bristol Bay, the front is not far removed from the place where ice is formed and little deformation occurs during transport. USE OF ICE HABITATS BY MARINE MAMMALS More than 25 species of marine mammals occur, to some extent, in the continental shelf waters of the Bering (Fay 1974). They cope, in one way or anoth- er, with four phases (seasons) of the annual ice cycle, the intensity and duration of which are annually somewhat variable. These phases include: ice-free
