This project is to measure fluctuation in the Earth's magnetic field on time scales between 0.1 s and 1000 s. These "micropulsations" are the result of the interaction between the solar wind and the Earth's magnetosphere. By studying these variations over periods of time comparable to a complete solar cycle and at a variety of locations, it is possible to learn more about how variations in the solar wind effect the Earth and man made systems. Magnetic variations have important effects on such systems as power grids and pipelines, and it may be important to predict such disruptions. This is now becoming possible, since satellite systems are in place to monitor the solar wind as well as to view solar activity. The main reason to do work of this nature is to obtain a better understanding of the world, but the prediction of space weather is also an important aspect.This project uses magnetometers that are distributed at high latitude in both the Antarctic and Arctic so, for that reason, the work is supported by both the Arctic and Antarctic programs of the Office of Polar Programs. The principal investigator is a professor at an undergraduate institution.

该项目的目的是测量地球磁场在0.1秒至1000秒时间尺度上的波动。 这些“微脉动”是太阳风和地球磁层相互作用的结果。 通过研究这些变化在一个完整的太阳周期的时间段内，在不同的位置，有可能更多地了解太阳风的变化如何影响地球和人造系统。 磁变化对电网和管道等系统具有重要影响，预测此类中断可能很重要。 这一点现在正在成为可能，因为已经有卫星系统监测太阳风和观察太阳活动。 开展这项工作的主要目的是为了更好地了解世界，但空间天气的预测也是一个重要方面。该项目使用分布在南极和北极高纬度地区的磁力计，因此，这项工作得到了极地方案办公室北极和南极方案的支持。 主要研究者是一所本科院校的教授。
