AMD - DIF Record(s) USAP-1738989_1 Abstract This data set contains unprocessed radar profiles collected with a GSSI 200 MHz Hyperstacking antenna near Winkie Nunatak, West Antarctica. This data was collected to estimate depth-to-bedrock along a subglacial ridge line at depths between 20 - 120 meters.
