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、新泽西理工学院、马里兰州大学和新罕布什尔州大学）的科学家之间的合作，目的是继续研究南极洲的极地电离层和磁层以及北极的磁共轭区。磁力计观测、高频宇宙噪声吸收测量（辐射测量）和极光光度测量将构成调查的基础。研究工作将涉及利用补充数据集与其他研究人员进行广泛合作。该项目将在南极和南极洲的麦默多站运行磁力计、成像和宽束测高仪以及双波长天顶光度计。此外，调查人员将与日本国家极地研究所的科学家一起在南极操作单色全天成像仪。该项目还将继续在南极和麦克默多提供数据采集系统，以便共同记录其他地球物理数据，并将这些数据提供给合作的调查人员。为了提高这些数据对一般科学界的有用性和及时性，将更新网络数据门户，以便能够接近实时地访问南极数据集。总体目标是了解影响磁层和高纬度电离层能量流动的相关物理过程。 该项目将提高我们对控制地球空间能量流动的内部和外部（即太阳风驱动）等离子体过程的理解。 该项目将研究的现象包括磁暴、磁亚暴、磁层和电离层等离子体不稳定性以及高能粒子从磁层沉降到电离层，该项目为参与大学的本科生提供参与科学研究的机会，包括在南极洲的实地考察。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小组的国际关系。
