Dotson Ice Shelf 100 MHz Ice-Penetrating Radar Data, 2020

Description

This dataset contains 100 MHz ground-based ice-penetrating radar data collected over the Dotson Ice Shelf during January 2020, stored as NetCDF files. Data was collected by the Thwaites-Amundsen Regional Survey and Network Integrating Atmosphere-Ice-Ocean Processes (TARSAN) team of the International Thwaites Glacier Collaboration (ITGC). Files contain both raw and processed data. Processed data includes surface elevation, theoretical hydrostatic disequilibrium, and both ice-ocean interface and relatively bright englacial layer picks. All elevation values are recorded in meters. All geographic information is referenced to the polar stereographic projection (EPSG:3031). The dataset also includes PDF files showing each profile and its location on the shelf, as well as a CSV file with information from the external GPS units that accompanied the radar units in the field.
