This project will conduct a magnetotelluric survey at the Ridge 2000 integrated studies site on the East Pacific Rise near 9 degrees north. Key questions to be addressed are: What is the distribution, vertical extent and volume fraction of melt present in the mid to lower crust? To what extent does hydrothermal circulation play a role in heat removal from the crust? To what extent is melt accumulated at the base of the crust? What, if any, connections exist between the crustal melt accumulations and the region of decompression melting deeper in the mantle?

该项目将在北部9度的东太平洋崛起的Ridge 2000综合研究地点进行磁性纤维素调查。 要解决的关键问题是：中壳中存在的熔体的分布，垂直范围和体积分数是多少？ 水热循环在从地壳中除去热量中起作用？ 熔体在地壳底部积聚在多大程度上？ 地壳融化积聚与减压区域之间的联系更深的区域之间存在什么联系？
