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.

这项工作将更多地揭示冰层厚度、基底融化速度的复杂特性，帮助科学家进一步了解彼得曼冰川前段解体的状况。

The optimal drilling site has to avoid possible areas of incoming water that would disturb the sediment, as well as areas of basal freezing, where lake water freezes to the underside of the ice.

最好的钻位是能避开有水的区域，因为水会破坏沉积物，也就是在完全冰冻的位置最好。
