This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The icePod system will consist of a suite of imaging sensors mounted in an external pod installed and operated on New York Air National Guard LC-130 aircraft during routine and targeted missions across Antarctica and Greenland. This system will be operated as a shared community research facility providing data to scientists and educators. Instrumentation will include a scanning laser for precise measurements of the ice surface, visible and infrared imaging cameras to document the ice surface structure and temperature, and ice-penetrating radar to recover ice thickness and constrain the distribution of water at the ice sheet bed. Geo-referencing of the measurements will be provided by precision GPS satellite data integrated with inertial technology. Using the icePod system, a majority of the remaining unexplored regions of East Antarctica will become open for study including several key regions in Antarctica. Data from the integrated icePod sensor system will enable novel studies of the dynamics of outlet glaciers, the stability of the West Antarctic ice sheet grounding lines, the nature of the water movement between subglacial lakes and on the role surface melt water plays in the seasonal acceleration of the Greenland ice sheet. This project could provide the integrated ice imaging system capable of measuring in detail both the ice surface and the ice bed. The icePod imaging system will leverage a newly available instrumented door plug developed for Department of Defense Special Forces applications that can be installed in any LC-130 rear troop door. This proposal will design, build, calibrate, test and commission the instrument over a five-year period. A scientific advisory committee will provide input to the icePod team to ensure the system meets the science community?s needs and an operations advisory group will provide input on aircraft operations, logistics, testing and certification. The goal of the icePod project is that the sensor system will become a facility operated for the science community and the data will be served to the science community through a NSF- supported polar data center. Students will be engaged in the development of icePod through design, construction and demonstration of sample measurement systems. The investigators will also build a network of educators who can access, understand and employ the data collected from the icePod, thereby engaging students with the science of environmental change and instrumentation development.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。 IcePod系统将由安装在纽约航空国民警卫队LC-130飞机上的外部吊舱中的一组成像传感器组成，并在常规行动中进行，并在南极和格陵兰岛进行了目标任务。该系统将作为共享社区研究机构运行，向科学家和教育者提供数据。仪器将包括一个扫描激光器，用于精确测量冰表面，可见和红外成像摄像头，以记录冰表面结构和温度，以及冰渗透雷达，以恢复冰的厚度并限制冰盖床上水的分布。测量的地理参考将通过与惯性技术集成的精确GPS卫星数据一起提供。使用ICEPOD系统，大多数剩余的东南极洲未开发地区将开放进行研究，其中包括南极洲的几个关键区域。来自集成的ICEPOD传感器系统的数据将使对出口冰川的动力学，南极冰盖接地线的稳定性，冰川湖下湖中水运动的性质以及表面融化水在Greenland Ice板的季节性加速中发挥作用。该项目可以提供能够详细测量冰面和冰床的集成冰成像系统。 ICEPOD成像系统将利用可在任何LC-130后部队门中安装的新的仪器插头开发的新仪器插头。该建议将在五年内设计，建造，校准，测试和委托该工具。一个科学咨询委员会将向ICEPOD团队提供意见，以确保系统满足科学界的需求，并且运营咨询小组将提供有关飞机运营，物流，测试和认证的意见。 IcePod项目的目标是传感器系统将成为科学界运营的设施，并且数据将通过NSF支持的极地数据中心向科学界提供给科学界。学生将通过设计，构建和演示样本测量系统来开发IcePod。调查人员还将建立一个可以访问，理解和采用从Icepod收集的数据的教育工作者网络，从而使学生了解环境变化和仪器开发科学。
