README This repository contains data and code necessary to reproduce the results in "Impacts of Glacial Isostatic Adjustment on Subglacial Water Routing since the Last Glacial Maximum" by Linda Pan, Emma J. MacKie, Jerry X. Mitrovica, Stewart S. R. Jamieson, Olga V. Sergienko, Robert P. Ackert Jr., and Kaighin A. McColl. A description of files: G18_LGM_BedTopo | Bed topography at LGM on a degree 512 Gauss-Legendre grid from G18 model (Gomez et al., 2018)G18_LGM_ice | Ice thickness at LGM on a degree 512 Gauss-Legendre grid from G18 model (Gomez et al., 2018) GLlat_512 | Latitude coordinates of degree 512 Gauss-Legendre grid GLlon_512 | Longitude coordinates of degree 512 Gauss-Legendre grid Antarctica_random_field.ipynb | Code used to generate topographic realizations with noise Antarctica residual variogram analysis.ipynb | Code used for residual variogram analysis Bed topography and ice thickness at the LGM for the A24 model (Albrecht et al., 2024) is publicly available. Bed topography, ice surface elevation, and ice thickness at present day are from Bedmachine Antarctica v3 (Morlighem et al., 2020) Calculations of subglacial flow paths were done with Antarctic Mapping Tools (Greene et al., 2017) and TopoToolbox (Schwanghart et al., 2014).
