Drainage System Masks in the Transantarctic Mountains, Antarctica

This data product is a set of drainage system boundary masks in the Transantarctic Mountains, Antarctica. These masks were developed to support a landscape evolution study but could be useful in other Antarctic applications. My regions of interest were determined by locating where topography converges to a single point, similar to the methodology used for delineating fluvial watersheds, except over ice instead of water. Masks were manually delineated using the Reference Elevation Model of Antarctica, a high-resolution DEM of the Antarctic Surface and the United States Geologic Survey (USGS) topography maps both provided by the Polar Geospatial Center. There are 36 drainage system masks in total merged into one shapefile. The shapefile attribute table contains 4 parameters: BasinValue, BasinName, Shape_Leng, and Shape_Area. BasinValue column contains a unique integer for each drainage area from 1-38 while BasinName contains the name of the closest major glacier for reference.
