Physical mechanisms for formation of strata at the surface of the ice sheet in the interior of the Antarctic ice sheet, and remote sensing for them with radio waves

利用穿越南极冰盖内部获得的雪/积雪样品和数据，我们研究了雪和积雪中地层形成的物理机制。主要研究结果包括南极洲沉积环境的空间分布、积雪密度的季节效应和冰下环境的空间分布。此外，我们还发现冰盖表面微波发射率的偏振比与雷达探测观测到的积累速率有很好的相关性。

Using the snow/firn samples and data obtained by traversing the interior of the Antarctic ice sheet, we studied physical mechanisms of the formation of the strata within snow and firn. Major findings include spatial distribution of the depositional environment in Antarctica, seasonal effects on firn density and spatial distribution of the subglacial environment. In addition, we found that polarization ratio of the microwave emissivity from the ice sheet surface is well correlated to accumulation rate observed by radar sounding.
