This project is a collaboration between scientists at four universities (Siena College The New Jersey Institute of Technology, the University of Maryland, and the University of New Hampshire) to continue studies of the polar ionosphere and magnetosphere from Antarctica and magnetically conjugate regions in the Arctic. Magnetometer observations, high frequency (HF) cosmic noise absorption measurements (riometry) and auroral luminosity measurements will form the basis the investigations. The research efforts will involve extensive collaboration with other investigators using complementary data sets. The project will operate magnetometers, imaging and broad-beam riometer, and 2-wavelength zenith photometers at South Pole and McMurdo Station in Antarctica. In addition the investigators will operate a monochromatic all-sky imager (ASI) at South Pole together with scientists from the National Institute of Polar Research (NIPR) in Japan. The project will also continue to provide the data acquisition systems at South Pole and McMurdo for the common recording of other geophysical data and the provision of these data to collaborating investigators. To enhance the usefulness and timeliness of these data to the general scientific community, web-based data portal will be upgraded so that the Antarctic data sets can be accessed in near-real time. The overall objective is to understand the relevant physical processes that affect the flow of energy in the magnetosphere and high-latitude ionosphere. The project will improve our understanding of the internal and external (i.e. solar wind driven) plasma processes that control the flow of energy in geospace. Phenomena that will be studied under this award include magnetic storms, magnetic substorms, magnetospheric and ionospheric plasma instabilities, and energetic particle precipitation from the magnetosphere into the ionosphere.The project provides opportunities for undergraduate students at the participating universities to be involved in scientific research that includes field work in Antarctica. The project also involves international relationships with science teams from Britain, Canada, Denmark/Greenland and Japan.

该项目是四所大学（锡耶纳学院新泽西大学，马里兰大学和新罕布什尔大学）的科学家之间的合作，继续研究了来自南极洲的极地离子层和磁层，北极和磁性结合区域。磁力计观测，高频（HF）宇宙噪声吸收测量值（RIOMETIRE）和极光发光度测量结果将构成研究的基础。研究工作将涉及使用互补数据集与其他研究人员进行广泛的合作。该项目将在南极洲的南极和麦克穆尔多站的磁力计，成像和宽光束ri仪以及2波长的Zenith光度计。此外，调查人员将与日本国家极地研究所（NIPR）的科学家一起在南极开设一个单色全天空成像仪（ASI）。该项目还将继续向South Pole和McMurdo提供数据采集系统，以共同记录其他地球物理数据，并向合作研究人员提供这些数据。为了提高这些数据对一般科学界的有用性和及时性，将升级基于Web的数据门户网站，以便可以在接近现实的时间内访问南极数据集。总体目标是了解影响磁层和高纬度电离层中能量流的相关物理过程。 该项目将提高我们对控制地理空间能量流的内部和外部和外部和外部（太阳能驱动）血浆过程的理解。 将根据该奖项进行研究的现象包括磁性风暴，磁性替代物，磁层和电离层等离子体不稳定性以及从磁层进入电离层的能量粒子沉淀。该项目为参与大学的大学生提供了机会，以参与参与大学的科学研究，其中包括在南方Antarctica的现场工作。该项目还涉及与来自英国，加拿大，丹麦/格陵兰和日本的科学团队的国际关系。
