Deskripsi
We conducted GPS observations on the Antarctic ice sheet in the vicinity of Syowa Station, during wintering of the 48th Japanese Antarctic Research Expedition (JARE-48). Continuous GPS data for about one year was obtained for the first time. The flow velocity of the ice sheet, as determined by GPS analysis was 5.1m/year, or 14mm/day, and the direction was WNW. The movement of the ice sheet was fairly constant and no seasonal variations in velocity were observed.
