This project is a combined controlled source electromagnetic and magnetotelluric study designed to resolve unambiguously the strike direction and depth extent of electrical anisotropy from the near-surface through the crust and upper mantle. The data collected will provide depth constraints on and alignment of the strain regime generated during the mid-ocean ridge crust formation, constraints on the extent an alignment of ductile flow during present day plate motion, depth of the thermal boundary layer that denotes the lithosphere, and insight into electrical conduction mechanisms in the mantle, particularly the proposal that hydrogen dissolved in olivine enhances conduction in the a-axis direction.

该项目是一项综合受控震源电磁和大地电磁研究，旨在明确解决从近地表到地壳和上地幔的电各向异性的走向和深度范围。收集的数据将提供关于大洋中脊地壳形成过程中产生的应变状态的深度约束和对齐、对当今板块运动期间韧性流动对齐的程度的约束、表示岩石圈的热边界层的深度，以及对地幔中的导电机制的洞察，特别是关于溶解在橄榄石中的氢增强了a轴方向的传导的提议。
