This project is part of a cooperative magnetotelluric experiment with the French on the South Pacific superswell. Instruments will be deployed for 4 months using French ships. The purpose is to determine conductivity structure beneath the superswell the data should help discriminate models of plumes and lithospheric thinning. Data will also be used to look at oceanographic motions and these will be used to remove noise from data for analysis of earth conductivity. Modelling will also be done. %%% Electromagnetic techniques provide data on the deep structure of the earth that cannot be obtained by other means. The data obtained here should proved a unique view of deep mantle plume structure that will be important for providing constraints on the effects of hot spots on oceanic lithosphere. Dr. Filloux is a pioneer in the field of oceanic electromagnetic sensing.

该项目是与法国在南太平洋超级水井上合作进行的大地电磁试验的一部分。仪器将使用法国船只部署4个月。这样做的目的是为了确定超井下的电导率结构，这些数据应该有助于区分羽流和岩石圈减薄的模型。数据还将被用来观察海洋运动，这些数据将被用来消除数据中的噪音，用于分析地球电导率。还将进行建模。电磁技术提供了其他方法无法获得的有关地球深层结构的数据。本文所获得的数据应该证明了深部地幔热柱结构的独特观点，这将对限制热点对大洋岩石圈的影响起到重要作用。Filloux博士是海洋电磁传感领域的先驱。
