Towards an early warning of Antarctic ice sheet collapse from seismology

该项目旨在为地震观测对南极东部大冰盖微小变化的敏感性奠定物理基础。这些冰盖很容易部分坍塌或加速消退。这种冰盖的早期变化可能发生在隐藏的冰-岩石界面区域，并可以通过穿过该区域的冰层、沉积物、水和基岩的地震信号的细微变化来检测到。该项目将进行计算机模拟，对现有数据进行测试，并研究两个案例研究，即奥罗拉盆地和威尔克斯盆地。这项研究的结果将为利用地震学预警冰盖崩塌提供基础，并有助于未来提高对海平面上升的复原力。

This project aims to establish a physical basis for the sensitivity of seismic observations to small changes in the great ice sheets of East Antarctica. These ice sheets are vulnerable to partial collapse or accelerated retreat. Early changes in such ice sheets may take place in the hidden ice-rock interface zone and could be detected by subtle changes in seismic signals that pass through layers of ice, sediments, water and bedrock in this zone. This project will undertake computer simulations, run tests on pre-existing data and examine two case studies, the Aurora and Wilkes Basins. The outcomes of this research will provide a basis for an early warning of ice sheet collapse using seismology, and contribute to future increased resilience to sea level rise.
