“We are the first and only ones in the world to drill through an ice stream. Half of Greenland’s loss of ice sheet mass occurs by way of ice streams, which are are like rivers of fast-flowing ice within the ice sheet that slide towards the sea and eventually calve to become icebergs. The prospects are significant, as we expect research results to provide improved forecasts with regards to rising sea levels in the future – an area now subject to great uncertainty,” according to the Niels Bohr Institute’s Dorthe Dahl-Jensen.
Researchers will study the ice core ice’s fluid-like properties by measuring physical properties and performing deformation studies of the ice core to better understand the material characteristics of the ice. The drill hole’s movement and deformation will also be measured.
