1-Km Bed Topography Digital Elevation Model (Dem) Of The Weddell Sea Sector, West Antarctica
We present a new bed elevation digital elevation model (DEM) of the Weddell Sea sector, West Antarctica. The DEM consists a total area of ~125,000 km 2 covering the Institute, Möller and Foundation ice streams and the Bungenstock Ice Rise with a 1 km spatial resolution. In order to produce the bed e...
