Regime of the Filchner-Ronne Ice Shelves, Antarctica

Seismic, radio-echo, TWERLE balloon and oceanographic data of the Filchner-Ronne ice shelves are analysed. A large thin area in the central Ronne Ice Shelf is found to differ from the morphology of the Ross and Filchner ice shelves. This area is partly filled by basal saline ice, which can be attributed to regional regelation caused by oceanic circulation
