GPS Measurements of Rock and Ice Motions in South Victoria Land

该奖项支持一项启动全球定位系统（GPS）测量南维多利亚地及其附近岩石运动的项目。研究结果将用于测试一些主要的冰盖变化和构造运动模型，特别是，大陆是否由于南极东部或西部冰负荷的减少而反弹，以及是否由于恐怖裂谷或南极横贯山脉的隆起而发生构造运动。一个测量冰运动的适度计划也将进行。其目的是测试艾伦山陨石集中区的冰流模型，并确定干谷的小冰川是在变厚还是变薄。纪念碑将被设置在岩石和冰中，并使用GPS接收器来确定其位置。以后几年的重复将决定运动。实地活动将涉及与美国地质勘探局的密切合作。

Whillans, Wilson, Goad OPP 9527571 Abstract This award supports a project to initiate Global Positioning System (GPS) measurements for rock motions in South Victoria Land and vicinity. The results will be used to test some of the leading models for ice-sheet change and tectonism, in particular, whether the continent is rebounding due to reduced ice load from East or West Antarctica and whether there is tectonic motion due to Terror Rift or uplift of the Transantarctic Mountains. A modest program to measure ice motion will be conducted as well. The motive is to test models for ice flow in the Allan Hills meteorite concentration region and to determine whether small glaciers in the Dry Valleys are thickening or thinning. Monuments will be set into rock and ice and GPS receivers used to determine their locations. Repeats in later years will determine motion. Field activities will involve close cooperation with the USGS.
