This will reveal more of the complex nature of the ice thickness, basal melt-rates and insight into the breakup at the front section of Petermann.
2010年冬天，雅各布港冰川的前沿并没有像往常一样重新前进，于是2010年融水季节是在2009年夏季融水季节结束的同一地点开始的。
In the winter of 2010, Jakobshavn's ice front did not re-advance as it usually does, so it began the 2010 melt season in the same location as the 2009 summer melt season.
此外，缺少了海冰将无法阻挡陆地冰川进入海洋，从而导致海平面上升。
