Detecting change in the outlet glaciers of East Antarctica using seismology

这项工作的目的是建立一种方法，通过分析流动的水或冰的破裂和滑动所产生的微小振动来探测南极洲东部大出口冰川的变化。 这些冰川的变化是非常重要的，因为它们阻止了未来海平面上升10米以上，但许多融化和运动过程从卫星上看是隐藏的。 预期成果包括利用地震信号进行偏远地区冰川监测的半自动化方法，以及关于今后在东南极洲关键地区部署具有成本效益的仪器的建议。 新的能力将是世界领先的和务实的，使加速未来沿海洪水影响澳大利亚的风险能够得到更好的预测。

This work aims to establish a way of detecting change in the great outlet glaciers of East Antarctica by analysing the small vibrations made by moving water or by cracking and sliding ice. Change in these glaciers is very significant because they hold back over 10 m of potential future sea level rise, but many melt and movement processes are hidden from satellite view. Expected outcomes include a semi-automated approach for remote area glacier monitoring using seismic signals, and recommendations for cost-effective future instrument deployments in key areas of East Antarctica. The new capability will be world-leading and pragmatic, enabling the risks of accelerated future coastal inundation affecting Australia to be better anticipated.
