结合大地测量，地球物理和冰川原位测量的解释有关的表面高度变化在冰下湖东方站和当地的冰盖质量平衡。5年的重复GPS观测和长期的表面积累数据表明，湖面高度在观测期间没有变化。将质量守恒方程应用于纯观测数据，可得出东方站接近平衡的冰质量平衡。
Combined geodetic, geophysical and glaciological in situ measurements are interpreted regarding surface height changes over subglacial Lake Vostok and the local mass balance of the ice sheet at Vostok station. Repeated GPS observations spanning 5 years and long‐term surface accumulation data show that the height of the lake surface has not changed over the observation period. The application of the mass conservation equation to purely observational data yields an ice mass balance for Vostok station close to equilibrium.
