Accelerating Flow of the Brunt Ice Shelf, Antarctica
Abstract Position fixes made at the British Antarctic Survey station, Halley, on the Brunt Ice Shelf are considered for the period 1968–82. These show an initial westward velocity of approximately 400 ma −1 rising to over 700 m a −1 by the end of the period. The data are well fitted by two straight...
