Abstract:Antarctica has an active subglacial hydrological system, with interconnected subglacial lakes fed by subglacial meltwater. Subglacial hydrology can influence basal sliding, inject freshwater into the sub‐ice‐shelf cavity, and impact sediment transport and deposition which can affect the stability of grounding lines (GLs). We used satellite altimetry data from the ICESat, ICESat‐2, and CryoSat‐2 missions to document the second recorded drainage of Engelhardt Subglacial Lake (SLE), which began in July 2021 and d… Show more
