Ice-Flow and Thickness Measurements in the Sør-Rondane, Dronning Maud Land, Antarctica
Abstract Velocity and ice-thickness profiles were measured un the western glaciers of the Sør-Rondane during the Expéditions Antarctiques Belges of 1959 and 1960 Some of the stations were re-occupied for velocity measurements during the Expédition Antarctique Belgo-Néerlandaise, Campagne d’Été 1964–...
