Gravity Measurements on the Barnes Icecap, Baffin Island
"A survey was made (during the Baffin Island Expedition of the Arctic Institute of North America, 1950) of the southeastern lobe of the Barnes Icecap to determine ice thickness and topographical features of the underlying rock surface by means of the gravimeter method. Gravity was measured at s...
