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.

Whillans，Wilson，Goad，邮编：9527571 摘要该奖项支持一个项目，以启动全球定位系统（GPS）测量岩石运动在南维多利亚土地和附近。 研究结果将用于测试冰盖变化和构造作用的一些主要模型，特别是南极洲东部或西部的冰负荷减少是否会导致大陆反弹，以及恐怖裂谷或跨南极山脉的隆起是否会导致构造运动。 还将进行一项测量冰运动的适度计划。 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变厚还是变薄。 纪念碑将被设置在岩石和冰和全球定位系统接收器用来确定他们的位置。 在以后的几年里，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。
