This research will assemble and deploy newly-developed time lapse camera systems at Columbia Glacier, Alaska, for combined scientific and public education/outreach use. Columbia Glacier is mid-way through a rapid dynamic retreat and its terminus is presently entering a confluence of two major branches where exceptionally rapid changes occurred in September 2006, and are likely to continue in 2007. Detailed observations made during Summer 2007 during what may be the fastest and most complex phase of the retreat to date will provide critical information for understanding the details of outlet glacier dynamics at the world's most intensively studied marine-terminating glacier. Deployment of ground-based camera systems greatly strengthen the documentation and analysis of retreat during this period of rapid and complex change. Broader Impacts: The newly-developed camera systems described here have greater capabilities than existing systems, both in terms of photogrammetric applications for extraction of quantitative information and in terms of intrinsic image quality for professional outreach. Time lapse imagery has a powerful informative influence on general public and scientific audiences alike; the imagery gathered under this funding will be used to address a wide variety of outreach and educational goals, in collaboration with the University of Colorado Outreach Education Office, National Geographic Society, and The North Face, Inc.

这项研究将在阿拉斯加的哥伦比亚冰川组装和部署新开发的延时摄影机系统，用于科学和公共教育/推广。哥伦比亚冰川正处于快速动态退缩的中途，其终点目前正进入两个主要分支的汇合处，2006年9月发生了异常迅速的变化，2007年可能会继续。2007年夏季期间可能是最快和最复杂的阶段撤退到目前为止，详细的观察将提供关键信息，了解出口冰川动态的细节，在世界上最深入研究的海洋终止冰川。在这一迅速而复杂的变化时期，部署地面摄像系统大大加强了对撤退情况的记录和分析。更广泛的影响：这里描述的新开发的相机系统在提取定量信息的摄影测量应用和专业外展的内在图像质量方面都比现有系统具有更大的能力。延时图像对公众和科学观众都有强大的信息影响;在此资金下收集的图像将用于解决各种各样的推广和教育目标，与科罗拉多大学外展教育办公室，国家地理学会和The North Face，Inc.合作。
