Quaternary geology and biology of the Jørgen Brønlund Fjord area, North Greenland
Prior to the last deglaciation, probably in the Late Weichselian, glaciers draining the Inland Ice were present in Independence Fjord and Jørgen Brønlund Fjord. and a glacier draining an ice cap in the north was present in the Børglum Elv valley. It is proposed that glacier fronts were situated at t...
