Actively evolving subglacial conduits and eskers initiate ice shelf channels at an Antarctic grounding line
The formation mechanisms of ice-shelf channels remain poorly understood. Here, using ice-penetrating radar data, the authors propose that ice-shelf channel morphology in the Roi Baudouin Ice Shelf, East Antarctica, is seeded by esker ridges, indenting the ice from below.
