This study will use a three.dimensional gravity and magnetics interpretation of existing geophysical data near the northern end of the Mariana Trough, which appears to be actively undergoing the transition from rifted to spreading crust. The study will utilize bathymetric, gravity and magnetics to calculate standard geophysical parameters and to claculate a sea floor magnetization solution in this backarc basin. The PI will collaborate with the proposed and ongoiong structural and petrological work of P. Fryer (University of Hawaii) and scientists from the Geological Survey of Japan.

这项研究将使用三维重力和 附近现有地球物理数据的磁力解释 马里亚纳海槽的北方末端， 正在经历从裂陷地壳到扩张地壳的转变。的 研究将利用测深、重力和磁力， 计算标准地球物理参数， 在这个弧后盆地的底部磁化溶液。PI将 与拟议的和正在进行的结构和 P. Fryer（夏威夷大学）的岩石学工作， 来自日本地质调查局的科学家。
