The Eastern Bering Sea Shelf The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder . easternberings00hood Year: 1981 Nearshore ice characteristics 171 Figure 11-3. Idealized Bering Sea nearshore ice regime showing effect of large tidal variations on fast ice. As depicted here low tide has caused the fracturing of floating fast ice and the breakup of attached fast ice. This effect tends to limit the extent and stability of Bering Sea fast ice. Advective export of Bering Sea nearshore ice £ilso contributes to the limitation of fast ice. There are many areas along the Bering coast where ice motion has a significant seaward component, and as a result, grounded ridges are seldom buUt in these locations. This condition contrasts sharply with that of near- shore ice in the Beaufort Sea, where the pack ice is nearly always present along the fast-ice boundary and is often driven along the fast ice with a shoreward component of force, thus creating the well-known shear ridges often found in that area. These two distinguishing influences, tidal fluctua- tions and ice advection, affect the Bering coast in varying degrees. At some locations they combine to severely limit the edge of fast ice to isobaths even less than 6 m. At other locations, conditions similar to those found in the Beaufort Sea prevail, with ice ridges grounded along the 20-m isobath.
