Description :
The AA. report and discuss a compilation of seafloor mapping data acquired during the 1998-1999 SCICEX nuclear-submarine expeditions and several icebreaker cruises. They focus on the 2 principal areas that contain the majority of mapped glaciogenic bedforms in the Arctic Ocean - the Chukchi Borderland and the central Lomonosov Ridge. A comparative analysis of glaciogenic morphologies from these areas allows a characterization of the impact of deep-draft ice on the central Arctic Ocean.
