a Geographical setting of SLM beneath West Antarctic Ice Sheet (WAIS), showing its position relative to glacial ice streams and the grounding line. The background satellite image is from the MEaSUREs MODIS Mosaic of Antarctica 2013-2014 (MOA2014) Image Map, Version 1 (NSIDC)97. Subglacial lake polygons (navy) are based on the Antarctic Active Subglacial Lake Inventory from ICESat altimetry (NSIDC)98. The light blue lines indicate the subglacial water flow paths beneath WAIS99, and the grounding line (light grey line) is derived from MEaSUREs Antarctic Grounding Line from Differential Satellite Radar Interferometry, Version 2100.
