Reactivation of a Subglacial Channel Around the Grounding Zone of Roi Baudouin Ice Shelf, Antarctica

Subglacial water beneath the Antarctic Ice Sheet is often funneled via subglacial channels, which inject freshwater into ice‐shelf cavities where it interacts with ocean water. The temporal variability of this system has been poorly observed, but its importance for ice dynamics is well recognized. A...
