Supplementary data for 'Melting and refreezing in an ice shelf basal channel at the grounding line of the Kamb Ice Stream, West Antarctica' Whiteford et al 2022
Description
These data are described in detail by 'Melting and refreezing in an ice shelf basal channel at the grounding line of the Kamb Ice Stream, West Antarctica' Whiteford et al 2022.
'ApRES dataset.zip' contains raw ApRES data and processed results from a spatial survey of basal mass balance, detailed in Sections 2.2.4 and 3.2.2 of the above paper. README.md describes the file contents.
'radar_dataset.tar.gz' contains raw data from a low frequency radar survey profiling ice thickness, detailed in Section 2.2.1 of the above paper.
'channel_base_surface_map' contains six files. *_Ice_thickness is raster data of an estimation of ice thickness in the area. This is produced through processing radar data 'radar_dataset.tar.gz' and interpolation, described in Sections 2.2.2 and 3.1.2. *_REMA_surf is raster data of the ice surface, sampled a REMA strip from 9 November 2016 (Howat 2019). Ice_base is raster data calculated by subtracting the ice thickness from this surface. *_x_grid and *_y_grid are the x and y UTM coordinates accompanying the raster data, in Antarctic Polar Stereographic projection. *_extent is the x and y extent of the area covered by raster data.
