Geophysical Research Letters, 47, e2019GL086663, doi:10.1029/2019GL086663 This directory contains the location and depth of internal reflection horizons (H1, H2 and H3) derived from the airborne ice-penetrating radar survey of Institute and Möller Ice Stream, West Antarctica, conducted in 2010/11. (1) Positions are given in Polar Stereographic South (EPSG: 3031) "X" and "Y" coordinates. (2) "Depth" is given as metres below the ice surface. (3) "FractionalDepth" is the depth divided by the ice thickness. (4) "Pick" is the pixel number below the ice surface of the radargram of that horizon. (5) "DistToBed" is distance in metres from the deepest horizon (H3) to the ice bed. Two sets of information are provided. > "Hx_Raw.csv" are high-resolution along-track depths derived from the picking software. > "Hx_500m.csv" are depths and fractional depths resampled to 500 m spaced points. These data are also provided combined in a GeoPackage for display in a GIS.
