REU: Japan-United States Cooperative Study of the Relationship between Sediment Physical Properties and Subduction Processes in the Nankai Trough

本项目是对西太平洋南开海槽沉积物物理性质与俯冲过程关系的野外和室内研究。该研究为控制活动大陆边缘沉积物中地质构造形成的过程提供了重要的新数据。现场项目的主要技术是先进的多通道地震反射数据采集，包括需要两艘船作业的扩展分布剖面。德克萨斯大学的R/V MOORE将与日本的R/V TANSEA MASU一起使用。这些数据将被共同分析并定义随时间和沉积物变形增加的物理性质变化。该项目还将提供所需的详细控制，以确定未来ODP钻探深孔的位置，以校准地震数据，并直接测量沉积物的地质和流体含量。G. Moore博士（塔尔萨大学）和T. Shipley博士（德克萨斯大学）正在与日本人合作进行这项研究。他们与Dr. D. Karig（康奈尔大学）和他们的合作研究人员一起，组成了一个非常强大的研究团队，在工作的所有组成部分都有经验。这包括野外作业、地震数据分析、大陆边缘地质和构造以及物理性质测量。

This project is a field and laboratory study of the relationship between the sediment physical properties and subduction processes in the Nankai trough in the western Pacific. The study is providing important new data on the processes that control the formation of geological structures in the sediments of active continent margins. The primary technique for the field program is advanced multichannel seismic reflection data acquisition including expanding spread profiles that require two ship operations. The R/V MOORE of the University of Texas will be used together with the R/V TANSEA MASU of Japan. The data will be jointly analyzed and define variations in physical properties with time and increasing deformation of the sediments. The project will also provide the detailed control needed to site a future ODP drilling deep hole for calibration of the seismic data and direct measurements of the geology and fluid content of the sediments. Dr. G. Moore (Univ. Tulsa) and Dr. T. Shipley (Univ. Texas) are collaborating on this study with the Japanese. Together with Dr. D. Karig (Cornell) and their co-investigators, they form a very strong research team with experience in all components of the work. This includes field operations, seismic data analysis, continental margin geology and tectonics, and physical property measurements.
