Basal melting and freezing of the Ross Ice Shelf (2019)
Antarctica’s ice sheets don’t end at the coast, they extend onto the sea around the continent as ice shelves where they buttress the ice sheets from accelerating. These ice shelves are where most glaciological mass of the Antarctic continent is lost through calving and basal melting. But processes below the ice shelf are often poorly understood through lack of direct measurements. Automatic phase sensitive radar echo sounding (pRES) systems allow the internal ice shelf layers and sea interface to surveyed to mm precision allowing monitoring of the basal conditions and processes beneath the ice shelf. This report analyses third year pRES data from the eastern Ross Ice Shelf. Basal processes are consistent with precious measurements and can be related to basal topology and confirm other studies findings.

Melting and deformation of the Ross Ice Shelf, Antarctica, by Multi-Year Phase Sensitive Radio Echo Sounding Snodgrass, Joseph A. (University of Canterbury, 2021)Antarctic ice shelves are an important part of the Antarctic ice sheet system, holding back the grounded ice front from accelerating onto the ocean and contributing to sea level rise. As ice shelves float on the ocean, ...
Can SMOS Ocean Salinity Data Detect a Link Between Increasing Antarctic Sea Ice Extent and Freshwater Flux from Basal Melting of Antarctic ice shelves? Schroeter, Serena (2015)The drivers behind the observed trend of increasing Antarctic sea ice extent are not yet well understood, though several potential drivers have been identified, such as the increased input of freshwater into the Southern ...
