(Table 1) Mass balance of different sectors in Antarctica in 2000

Area: area surveyed. Glacier discharge: grounding-line ice flux of surveyed area. Mass balance (net) calculated as input (accumulation) minus outflow (discharge). Net+: mass balance scaled on the basis of total area (area+) versus area surveyed (area), except for basin II''. Input: snow accumulation of surveyed area, input+: total snowfall in area+.
