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，以结合科学和公共教育/推广使用。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交汇处，在2006年9月发生了异常迅速的变化，并可能在2007年继续。在2007年夏季进行的详细观测可能是迄今为止退缩最快和最复杂的阶段，将为了解世界上研究最深入的海洋冰川出口冰川动态的细节提供关键信息。地面摄像系统的部署大大加强了在这一快速和复杂变化时期对撤退的记录和分析。更广泛的影响：这里描述的新开发的相机系统比现有系统具有更大的功能，无论是在提取定量信息的摄影测量应用方面，还是在专业外展的内在图像质量方面。延时图像对普通公众和科学观众都有强大的信息影响；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，在这笔资金下收集的图像将用于解决各种外展和教育目标。

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.
