Joint U.K./U.S.-Controlled Source E.M. Experiment over the Reykjanes Ridge

本项目利用英国剑桥大学和达勒姆大学、澳大利亚弗林德斯大学和美国斯克里普斯海洋研究所的资源，对雷克雅内斯海岭一段轴向火山区进行地震和电磁联合研究。该研究将使用(1)沿轴向火山脊和跨轴向火山脊的广角地震剖面来确定地壳结构，(2)以火山脊为中心的详细电磁测深实验来确定地壳电导率结构，以及(3)一组长。天线电场仪器和磁力计通过控制和自然源电磁测深来确定脊轴下地幔的深层电导率结构。

This is a project to conduct a combined seismic and electromagnetic study of the axial volcanic region of a section of the Reykjanes Ridge using the resources of Cambridge and Durham Universitites (UK), Flinders University (Australia), and Scrips Institution of Oceanography (US). The Study will use (1) wide angle seismic profiles along and across an axial volcanic ridge to determine the crustal structure, (2) a detailed electromagnetic sounding experiment centered on the ridge to determine crustal electrical conductivity structure, and (3) an array of long.antenna electric field instruments and magnetometers to determine the deeper conductivity structure in the mantle beneath the ridge axis by both controlled and natural source electromagnetic sounding.
