Circum-Antarctic data used in "Tipping point behaviour of ice-sheet grounding-zone melting due to ocean water intrusion" by Bradley and Hewitt

The file 'Antarctica-data.mat' contains the following fields: 'x' [units: m] x position of grid points 'y' [units m] y position of grid points 'tf_max' [units: C] maximum thermal forcing from Adusumilli et al. 2020 (doi: https://doi.org/10.1038/s41561-020-0616-z) 'H' [units: m] ice thickness from Bedmachine V3 'B' [units: m] bed elevation from Bedmachine V3 'mask' [units: n/a] Bedmachine V3 mask 'isedge' [units: n/a] Logical array with 1 corresponding to edges of ice shelves and 0 otherwise 'isgl' [units: n/a] Logical array with 1 corresponding to grounding line points and 0 otherwise 'isfront' [units: n/a] Logical array with 1 corresponding to ice fronts and 0 otherwise 'vx' [units: m/a] Ice velocity in the x-direction from ITS_LIVE 240m mosaic 'vy' [units: m/a] Ice velocity in the y-direction from ITS_LIVE 240m mosaic
