Glacio-isostatic effects on geodetic data: Ice and sea level implications

冰川-均衡（GI）效应记录在地质和大地数据集中，并掩盖了其他变形过程。该项目建立在过去使用地质数据的工作基础上，重点是将大地测量和地质证据结合起来，以提高对过去冰盖的认识，分离出过去和现在的冰川消融的影响，并开发改进的地幔流变模型，以包括地幔响应的时间依赖性（首先是瞬态蠕变）。该项目的目的是提供一个与地质证据相一致的、完整的、可预测的地理变化对大地测量数据影响的描述，以便在不受这些影响的情况下估计其他构造、水文和海平面信号。

Glacio-isostatic (GI) effects are recorded in geological and geodetic data sets and mask other deformational processes. This project builds on past work using geological data with a focus on combining geodetic and geological evidence to improve knowledge of the past ice sheets, separate out effects of past and present deglaciation and develop improved models for the mantle rheology to include time-dependencies in mantle response (transient creep in the first instance). The project aims to provide a complete and predictive description of the GI effects on geodetic data, consistent with geological evidence, such that other tectonic, hydrologic and sea-level signals can be estimated free of these effects.
