This project, which is partially supported by a fund transfer to USGS, will collate magnetometer data collected over the past 33 years (since the IGY) at 27 different sites in Antarctica. The purposes of the investigation are: 1.. .To search for a response of the ionospheric E.region current system to the development of the annual ozone hole. This is expected since the ozone controls stratospheric warming and consequently the thermal expansion of the atmosphere, which has a strong effect on upper atmospheric currents;. H. 2.. .To establish hemispherical differences in magnetic field variation behavior;. H. 3.. .To evaluate the equivalent south polar region current systems for geomagneticly quiet days; and. H. 4.. .To determine the upper.mantle Earth electrical conductivity profile beneath the antarctic continent.. H.

这个项目部分由转移到美国地质勘探局的资金支持，它将整理过去33年来（自IGY以来）在南极洲27个不同地点收集的磁力计数据。调查的目的是：1.……寻找电离层e区电流系统对年臭氧空洞发展的响应。这是预期的，因为臭氧控制平流层变暖，从而控制大气的热膨胀，这对高层大气流有强烈的影响；H.……建立磁场变化行为的半球差异；3.……地磁平静日南极地区等效电流系统的评价；和。4.……确定鞋面。南极大陆下地幔地球电导率剖面H。
