SGER: Photogrammetric/Media Camera Support for Alaska Glacier Observations

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相机系统，用于科学和公共教育/推广相结合的用途。哥伦比亚冰川正在经历一次快速的动态退缩，其末端目前正进入2006年9月发生异常迅速变化的两个主要分支的交汇处，并可能在2007年继续下去。在2007年夏季可能是迄今为止最快、最复杂的退缩阶段进行的详细观察，将为了解世界上研究最深入的海洋终止冰川的出口冰川动力学细节提供关键信息。部署陆基摄像系统大大加强了在这一迅速而复杂的变化期间对撤退情况的记录和分析。更广泛的影响：这里介绍的新开发的相机系统在用于提取定量信息的摄影测量应用程序和用于专业外联的内在图像质量方面都比现有系统具有更大的能力。时间推移图像对普通公众和科学受众都有强大的信息性影响；根据这一基金收集的图像将与科罗拉多大学外联教育办公室、国家地理学会和The North Face，Inc.合作，用于实现广泛的外联和教育目标。

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.
