GlaDS subglacial hydrology model outputs and radar reflectivity data for Institute Ice Stream (IIS), Mӧller Ice Stream (MIS), Support Force Glacier (SFG), and Foundation Ice Stream/Academy Glacier (FIS-AG), Antarctica
The GlaDS_Weddell_outputs.txt file includes the following: Glacier Drainage System (GlaDS) model inputs: node easting (m), node northing (m), bed elevation (m), ice thickness (m), basal velocity (m/year) and basal water production (m/year). GlaDS model results for water pressure as a fraction of ove...

| Summary: | The GlaDS_Weddell_outputs.txt file includes the following: Glacier Drainage System (GlaDS) model inputs: node easting (m), node northing (m), bed elevation (m), ice thickness (m), basal velocity (m/year) and basal water production (m/year). GlaDS model results for water pressure as a fraction of overburden (Pw/Pi), water depth (m), and channel discharge (m3/s):base line model, low conductivity, high conductivity, and 1.5* basal water model runs. FIS_AG_reflectivity.txt includes the following: Radar basal reflectivity (calculated as relative values to a zero mean) for Foundation Ice Stream-Academy Glacier (see Jeoffry et al, 2018 for details): easting (m), northing (m), and reflectivity (dB). Easting and northing values are for an WGS84 Antarctic Polar Stereographic projection. References Jeofry, H. et al. Hard rock landforms generate 130 km ice shelf channels through water focusing in basal corrugations. Nat Commun, 9, 1-9 (2018). |
