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".

在南极最大的亚冰湖北部北部没有关于冰表面运动的原位观察。然而，观察到的速度是了解复杂系统“ Vostok湖”的冰动力学和冰/水相互作用的重要数量。在项目中，此数据差距将与俄罗斯合作伙伴密切合作。此外，在冰/水边界处的质量平衡计算和底部熔化/重新冻结计算将使用冰/底部的冰厚度观测和冰厚度观测，以更好地理解和建模系统“ Vostok湖”。
