The effect of possible Taylor columns on the summer ice retreat in the Chukchi Sea.

Abstract:      The Chukchi Sea topography consists of a broad, flat, 50-m-deep
               plain, with two prominent shoals, Herald and Hanna, which have
               horizontal dimensions of about 100 km and rise to depths of
               about 30 m. Herald Shoal in particular is a prominent, isolated
               seamount which, because of the warm water flux in summer
               through Bering Strait, has a warm 0.1 m s/sup -1/ flow incident
               upon it.  Examination of active and passive microwave imagery
               of the region for 1992-1994 shows that as the general ice cover
               recedes, the ice remains preferentially over Herald Shoal for
               3-4 weeks after the surrounding ice has melted.  A scale
               analysis suggests that the cause of the ice persistence is the
               formation of a Taylor column over the shoal, which traps cold
               water and ice above it.  A similar trapping of ice occurs over
               Hanna Shoal and on its eastern slope, but the response is
               complicated by a very different topography and the northward
               flow down Barrow Canyon.
