南極の氷は水面に浮かんでいる？
For early Antarctic explorers seeking to reach the South Pole, the Ross Ice Shelf became a starting area. In a first exploration of the area by the Discovery Expedition in 1901-1904, Robert Falcon Scott made a significant study of the shelf and its surroundings from his expedition's base on Ross Island. By measurement of calved ice bergs and their buoyancy, he estimated the ice sheet to be on average 900 feet thick; the undisturbed morphology of the ice sheet and its inverted temperature profile led him to conclude it was floating on water; and measurements in 1902-1903 showed it had advanced 608 yards northwards in 13.5 months. The findings were presented at a lecture entitled "Universitas Antarctica!" given 7 June 1911 and were published in the account of Scott's second expedition (the Terra Nova Expedition of 1910-1913).
