(2020) Englacial Architecture and Age-Depth Constraints Across the West Antarctic Ice Sheet. 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.<br> (2) "Depth" is given as metres below the ice surface.<br> (3) "FractionalDepth" is the depth divided by the ice thickness.<br> (4) "Pick" is the pixel number below the ice surface of the radargram of that horizon.<br> (5) "DistToBed" is distance in metres from the deepest horizon (H3) to the ice bed. Two sets of information are provided.<br> > "Hx_Raw.csv" are high-resolution along-track depths derived from the picking software.<br> > "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.
