Abstract : The main objective of this grant was to describe and to understand the dynamics of wide canyons in the Arctic Ocean. Barrow Canyon at the north-western tip of Alaska is such a wide canyon, because its width is large relative to its internal deformation radius. This canyon was the focus of a dynamical study from aboard the CCGS Henry Larsen in the summer of 1993. An acoustic Doppler current profiler was towed besides the icebreaker and provided data that described the velocity field within the canyon in all three spatial dimensions. Hydrographic data from a CTD (provided by Dr. Carmack of the Institute of Ocean Sciences, Canada) and current meter mooring data (generously provided by Dr. Weingartner of the University of Alaska) complements the data set that was analyzed as part of this grant.
