Temporal evolution of the Petermann Ice Shelf estuary constrained by satellite remote sensing observations
Supraglacial rivers may reduce ice-shelf instability by draining meltwater from the ice-shelf surface, limiting loading-induced stresses from ponded meltwater. However, if a supraglacial river incises to below sea level at the ice-shelf front, forming an estuary, this effect may be negated. Water flow reversal in the e...
