Development of an Ice Imaging System for Monitoring Changing Ice Sheets Mounted on the NYANG LC-130

哥伦比亚大学的拉蒙特-多尔蒂地球天文台获得了一项多年赠款(2010年5月1日至2015年4月30日)，用于开发一种冰成像系统，即“冰舱”，用于测量冰盖的表面和亚表面地形。冰舱将使研究全球气候变化对冰盖的影响以及冰下水对潜在海平面上升的影响成为可能。冰舱传感器包含在通用科学支持舱中，在格陵兰岛和南极洲上空执行例行和有针对性的任务时，在南洋LC-130飞机上运行。IcePod仪器包由穿冰雷达、红外和可见光相机、激光高度计、惯性测量单元、GPS接收器和数据采集系统组成。冰舱还将使其他仪器能够在模块化的共同科学支持舱中使用，并将成为向科学界提供数据的共享社区研究设施。资金将支持格陵兰和南极洲的活动，这些活动需要投入使用冰舱，开发冰舱数据的数据缩减流和数据交付系统，并设计不间断电源，为冰舱系统运行提供清洁、可靠的电力。

The Lamont-Doherty Earth Observatory of Columbia University was awarded a multi-year grant (May 1, 2010- April 30, 2015) to develop an ice imaging system, or "IcePod," for use in measuring the surface and subsurface topography of ice sheets. IcePod will enable research on the effects of global climate change on ice sheets and the effects of sub-glacial water on potential sea-level rise. IcePod sensors are contained in a Common Science Support Pod and operated on NYANG LC-130 aircraft during routine and targeted missions over Greenland and Antarctica. The IcePod instrument package consists of ice-penetrating radar, infrared and visible cameras, laser altimeter, inertial measurement unit, GPS receiver and data acquisition system. IcePod will also enable other instruments to be used in the modular Common Science Support Pod, and will become a shared community research facility providing data to the science community. Funding will support activities in both Greenland and Antarctica needed to commission IcePod, to develop a data reduction flow and data delivery system for IcePod data, and to engineer a UPS to provide IcePod with clean, reliable power for system operation.
