This project will test the feasibility of measuring the global electric circuit from Antarctica. The instruments will measure the vertical electric current from which the ionospheric potential can be deduced. The test will involve placing two of the current measuring instruments about one kilometer apart at South Pole Station. If the instruments are successful in producing the same measurement to within a few percent, then it is expected that they will at a later date be installed in Automatic Geophysical Observatories (AGO) at widely separated sites in Antarctica. It is the eventual goal of the investigation to be able to generate a geoelectric index, similar to the geomagnetic indices, and also be able to measure the cross polar cap potential differences. These have both been goals of the geophysics community for many years, but until now, with the development of the AGO system for the uniquely favorable antarctic environment, it has not been feasible to make the required measurements.

该项目将测试测量全球 来自南极洲的电路。 仪器将测量 电离层电位的垂直电流 可以推断。 测试将包括将两个电流 测量仪器在南极相距约一公里 站 如果这些仪器成功地生产出同样的 测量到百分之几以内，那么预计他们 将在稍后的日期安装在自动地球物理 在南极洲相距甚远的地点建立的天文台。是 调查的最终目标是能够产生一个 地电指数，类似于地磁指数，也是 能够测量跨极冠电位差。 这些 多年来都是地球物理学界的目标， 但到目前为止，随着AGO系统的发展， 独特有利的南极环境， 进行所需的测量。
