Processed ship-based Navigation Data from the Nankai Trough Subduction Zone acquired during the Maurice Ewing expedition EW9907 (1999)

This data set was acquired with a ship-based Navigation system during Maurice Ewing expedition EW9907 conducted in 1999 (Chief Scientist: Dr. Nathan Bangs). These data files are of Text File (ASCII) format and include Navigation data and were processed after data collection. Data were acquired as part of the project(s): A 3-D Seismic Investigation of the Aseismic to Seismic Transition along the Eurasian-Phillippine Sea Plate Boundary: U.S.-Japan Cooperative Program, Seismic Velocity, Compaction, and Pore Pressure in Underthrust Sediments, Nankai Subduction Zone, and A 3-D Seismic Investigation of the Sediment-to-Rock Transition and Its Relationship to Nankai Subduction Thrust Seismicity: U.S.-Japan Collaborative Program, and funding was provided by NSF grant(s): OCE02-41375, OCE02-41380, OCE02-41482, OCE97-30637, OCE98-02264, and OCE98-02295.

本数据集系1999年开展的EW9907号Maurice Ewing科考航次（首席科学家：内森·班斯博士）中，依托船载导航系统（ship-based navigation system）采集所得。本次产出的数据文件采用文本文件（ASCII）格式，包含导航数据，且已在数据采集完成后完成预处理。
本数据集的采集隶属于以下三项研究项目：其一为沿欧亚板块-菲律宾海板块边界的无震至发震过渡带三维地震调查：美日合作项目；其二为南海海沟俯冲带逆冲沉积物中的地震波速、压实作用与孔隙压力研究；其三为沉积物-岩石转变带及其与南海海沟俯冲逆冲带地震活动关系的三维地震调查：美日合作项目。
本研究获得美国国家科学基金会（National Science Foundation, NSF）的以下资助项目支持：OCE02-41375、OCE02-41380、OCE02-41482、OCE97-30637、OCE98-02264及OCE98-02295。
