There exist no in-situ observations on ice surface motion in the northern part of the largest subglacial lake in Antarctica. Observed velocities, however, are important quantities to understand ice dynamics and ice/water interactions of the complex system "Lake Vostok". Within the project this data gap will be closed in close cooperation with Russian partners. Furthermore, colocated surface height and ice thickness observations and the velocities will be used for mass balance computations and bottom melting/refreezing calculations at the ice/water boundary to better understand and model the system "Lake Vostok".

在南极洲最大的冰下湖的北方部分，没有对冰面运动的现场观测。然而，观测到的速度是理解复杂系统“东方湖”的冰动力学和冰/水相互作用的重要量。在该项目中，将与俄罗斯合作伙伴密切合作，填补这一数据缺口。此外，还将利用同地观测的表面高度和冰厚以及速度进行冰/水边界处的质量平衡计算和底部融化/再冻结计算，以更好地了解“东方湖”系统并对其进行建模。
