Earth’s response to ice unloading: a unique GPS measurement from Antarctica

地球对冰卸载的反应--来自南极洲的独特的GPS测量：该项目旨在南极洲内部署地球物理设备，包括全球导航卫星系统，以了解地球如何对地壳和上地幔(上部~660公里)内的应力(流变学)变化做出反应。它利用了一项全球独一无二的自然实验，该实验始于2002年拉森B冰架的破裂，随后是大规模的冰块卸载和快速的表面变形。新的宽带被动地震和大地形变测量通过独特地研究介于这两个极端之间的时间尺度，有望解决实验室和千年尺度的地球流变学测定之间的二分法，同时进一步加强澳大利亚在极地地球物理方面的新兴专业知识。

Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km). It exploits a globally-unique natural experiment that commenced in 2002 with the break-up of the Larsen B Ice Shelf and which was followed by large-scale ice-mass unloading and rapid surface deformation. New broadband passive seismic and geodetic deformation measurements offer the promise of resolving a dichotomy between laboratory and millennial-scale determinations of Earth rheology through uniquely studying a time-scale mid-way between these extremes, whilst further strengthening Australia's emerging expertise in polar geophysics.
