Uncovered bathymetry under Antarctica’s fourth largest ice shelf reveals potential for seasonal warm water inflow Open
Interactions of ice and ocean around Antarctica determine the stability of ice shelves and the onshore ice masses they buttress. These interactions and the exchange of water between the open ocean and ice shelf cavities depend heavily on s…

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

Spatial and temporal changes in surface mass balance derived from airborne radio sounding for the plateau area in Dronning Maud Land Open
Contrary to the rest of the Antarctic ice sheet, East Antarctica currently gains mass due to an increase in snow accumulation over the last decades. How or if this increase is linked to anthropogenic warming is not yet clear and requires b…
