Ice Recession in Dronning Louise Land, North-East Greenland [PDF]

open access: yesJournal of Glaciology, 1956
AbstractThe existence of high rock thresholds beneath the glaciers of Dronning Louise Land is established and examples are described. It is concluded that decrease in the height of the Greenland Ice Cap and the consequent emergence of the rock thresholds is the dominant factor in the final stages of recession of the glaciers of Dronning Louise Land. It
