Bed topography of Princess Elizabeth Land in East Antarctica
We present a topographic digital elevation model (DEM) for PrincessElizabeth Land (PEL), East Antarctica. The DEM covers an area of ∼900 000 km 2 and was built from radio-echosounding data collected during four campaigns since 2015. Previously, togenerate the Bedmap2 topographic product, PEL's...
