Ice-Radar and Satellite Remote-Sensing Studies of Glaciers and Ice Sheets, II

冰雷达和卫星遥感对冰川和冰盖的研究II该项目是为了继续资助科技大学本科生研究经验(REU)站点。奥拉夫学院和南卡斯喀特冰川，华盛顿州自1987年以来，在国家科学基金会的支持下，圣奥拉夫冰雷达一直是了解西南极冰盖动态的努力的一部分。圣奥拉夫对这一项目的贡献是开发和部署了一个陆基雷达系统，用于研究流入罗斯冰架的几个快速冰流。通过目前的REU奖，该小组最近参与了利用卫星图像获取冰的速度--这是雷达的一个补充工具，也用于了解冰的动力学。与此同时，圣奥拉夫与美国地质调查局的科学家合作，在华盛顿州南喀斯喀特冰川开展了一项积极的研究计划。除了作为南极雷达系统的测试和开发地点外，这座冰川还是一项深入努力的重点，以调查冰川和冰下排水和水文学问题。对南卡斯喀特冰川的研究还为学生提供了实地体验冰川科学的场所，并计划和进行他们自己设计的类似于在极地地区所做的实验。这项提议将使本科生能够参与正在南极洲西普尔穹顶进行的雷达和冰动力学研究的数据简化和分析阶段。它还将资助对该地区冰速度的补充研究，使用卫星图像来回答有关圆顶周围冰流的短暂性质的问题。该提案支持继续开展南级联冰川的实地工作，以研究冰川水文学问题和雷达系统的进一步发展。

Ice-Radar and Satellite Remote Sensing Studies of Glaciers and Ice Sheets II This project is for continued funding of the Research Experiences for Undergraduates (REU) Site at St . Olaf College and South Cascade Glacier, WA. Since 1987, with support form NSF, the St. Olaf ice radar has been part of the effort to understand the dynamics of the West Antarctic ice Sheet. The St. Olaf contribution to this prmject has been the development and deployment of a ground-based radar system used in studies of several of the fast ice streams which drain into the Ross Ice Shelf. Through the current REU award, the group has more recently become involved in the use of satellite imagery for obtaining ice velocities - a complementary tool to the radar also used for understanding ice dynamics. At the same time, St. Olaf has carried out an active research program on South Cascade Glacier, WA in collaboration with scientists in the U.S. Geological Survey. In addition to serving as a testing and development site for the Antarctic radar system, this glacier has been focus of an intensive effort to investigate the problem of englacial and subglacial drainage and hydrology. Studies on South Cascade Glacier also provide and accessible site for students to experience glaciological science in the field, and to plan and carry out experiments of their own design similar to those done in the polar regions. This proposal will enable undergraduate students to participate in the data reduction and analysis phase of radar and ice dynamical studies being carried out on Siple Dome, Antarctica. It will also fund a complementary study of ice velocities in this area using satellite imagery to answer questions about the transitory nature of the ice streams surrounding the dome. The proposal supports continued field work mn South Cascade Glacier to study problems of glacial hydrology and further developments of the radar system.
