Short summary
Ice rises are locally grounded features surrounded by ice shelves. They help to stabilize the Antarctic Ice Sheet and in turn are affected by ice-sheet evolution. However, details of these influences depend on the glaciological settings of the ice rises. We first present detailed ground-based investigations from Blåskimen Island ice rise in East Antarctica. We found that the ice rise is at least ~ 600-years old and has been thickening by ~ 0.3 m per year over the past decade.
