New bathymetry compilation of the Amundsen Sea continental shelf
The Amundsen Sea continental shelf is one of the remotest areas of coastal Antarctica, and was relatively unexplored until the late 1980s. Over the last two decades, however, oceanographic and geological interest has led to several cruises, one result of which is that there is now sufficient bathyme...

The Amundsen Sea continental shelf is one of the remotest areas of coastal Antarctica, and was relatively unexplored until the late 1980s.

We have combined the available multibeam and single beam bathymetry data from this region and created a new regional bathymetric map of the Amundsen Sea continental shelf and slope.
