Earthquake biases in measurements of Antarctica's sea-level contribution

该项目旨在准确确定南极洲对当今海平面的影响。大的特定于技术的系统误差使得这个不确定和有争议的变化的标志不一致。四种测量技术中有三种依赖于了解固体地球形状或重力场的变化。研究没有考虑地震后的变形，但GPS数据显示，自1998年8.2级南极板块地震以来，南极洲已经变形。该项目将开发一个受大地测量数据约束的地震模型，并利用该模型估计南极洲对海平面变化的影响。这将使地方、国家和国际规划更加自信。这将通过减少海平面预测的不确定性而造福社会。

This project aims to accurately determine Antarctica’s contribution to present-day sea-level. Large technique-specific systematic errors make this uncertain and controversial with the sign of change not agreed. Three of four measurement techniques rely on knowing the solid earth's changing shape or gravity field. Studies have not considered post-seismic deformation, but GPS data show that Antarctica has deformed since the 1998 Magnitude-8.2 Antarctic Plate Earthquake. This project will develop a model of these earthquakes constrained by geodetic data and use the model to estimate Antarctica's contribution to sea-level change. This should enable more confident local, national and international planning. This will benefit society through reducing the sea-level projection uncertainty.
