The Gamburtsev subglacial mountains are thought to be the birthplace of the vast East Antarctic Ice Sheet.
甘毕采夫冰下山脉被认为是辽阔的东南极冰盖的发源地。
Until February, it had been the tongue of the Mertz Glacier, sticking out from the East Antarctic ice sheet into the Southern Ocean.
到二月，它已然成为了默茨冰川的突出部分，从东南极冰盖延伸入南大洋。
Uncertainties in the model gave the scientists only a broad estimate of ice loss in the East Antarctic ice sheet of between 5bn and 109bn tonnes a year.
该模型的不确定性导致其结果只能给科学家一个大致的估计：南极东部冰盖的消融速度介于每年50亿吨和1090亿吨之间。
Furthermore, sea level fluctuated tens of meters during this interval, suggesting a highly volatile East Antarctic Ice Sheet when CO2 concentrations were near this threshold value.
此外，海平面在数十米区间内的波动，表明在二氧化碳接近这个临界值时东南极洲冰盖会产生剧烈蒸发。
The survey confirmed the West Antarctic ice sheet is melting rapidly with the loss of around 132bn tonnes of ice a year, but revealed unexpected melting in the larger East Antarctic ice sheet.
这项调查证实，南极西部冰盖正以每年约1320亿吨的速度迅速融化，但同时也显示，面积更大的南极东部冰盖正出乎意料地逐渐消融。
Presently, most research is concentrated on the coastal ice shelves of WAIS (West Antarctic ice Sheet), very few work has been done for in-land glaciers in East Antarctica.
目前的研究重点主要在西南极沿岸冰架地区，东南极内陆冰盖地区涉足很少。
