DH-GAP04 borehole hydraulic head, 2011 to 2018, Greenland ...
The 650 m long proglacial bedrock borehole DH-GAP04 is angled under the Greenland Ice Sheet and is the only bedrock borehole in the Arctic providing deep groundwater information at an active ice sheet setting. DH-GAP04 is drilled at the Greenland ice sheet margin and the lower part of the borehole e...
