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.

冰川和冰盖的冰雷达和卫星遥感研究2 该项目是继续资助研究经验的本科生（REU）网站在圣。奥拉夫学院和南喀斯喀特冰川，华盛顿州。 自1987年以来，在NSF的支持下，圣奥拉夫冰雷达一直是了解南极西部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地基雷达系统，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得冰速度的工作-这是雷达的一个补充工具，也用于了解冰的动态。 与此同时，圣奥拉夫与美国地质调查局的科学家合作，对西澳的南喀斯喀特冰川进行了积极的研究。 除了作为南极雷达系统的测试和开发地点外，该冰川一直是研究冰内和冰下排水和水文问题的密集努力的重点。 对南喀斯喀特冰川的研究还为学生提供了一个方便的地点，让他们在实地体验冰川学科学，并计划和进行自己设计的实验，类似于在极地地区进行的实验。 这一提议将使本科生能够参加正在南极洲西普尔穹进行的雷达和冰动力学研究的数据整理和分析阶段。 它还将资助一项补充研究，利用卫星图像对该地区的冰速进行研究，以回答有关圆顶周围冰流的短暂性质的问题。 该提案支持继续在南喀斯喀特冰川进行实地工作，研究冰川水文学问题和雷达系统的进一步发展。
