Three-Dimensional Survey of the Crust, Moho, and Mantle Nearthe East Pacific Rise

最近对海底地震仪数据的分析表明，在年轻的海洋地壳底部存在非常低刚度的体。这些数据是在与莫霍地震波相互作用后纵波向横波的转换。该项目将利用广泛的海底地震仪调查以及同步和独立的短流线多通道地震数据，绘制Moho的压缩-剪切反射率图。此次调查将在北12度54分重叠扩散中心附近的东太平洋隆起进行。

Recent analysis of ocean bottom seismometer data indicates the presence of very low rigidity bodies at the base of young oceanic crust. The data are conversions of compressional waves to shear waves upon interaction with the Moho. This project will map compressional-to-shear reflectivity of the Moho, using an extensive ocean bottom seismograph survey along with simultaneous and independent short-streamer multichannel seismic data. The survey will be conducted on the East Pacific Rise near the overlapping spreading center at 12 degrees 54 minutes north.
