Processed ship-based Navigation Data from the Izu-Bonin-Mariana Subduction Zone acquired during the Wecoma expedition W0404A (2004)

This data set was acquired with a ship-based Navigation system during Wecoma expedition W0404A conducted in 2004 (Chief Scientist: Dr. Douglas Wiens). 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): US-Japan Collaborative Research: Multi-Scale Seismic Imaging of the Mariana Subduction Factory (MARIANA), and funding was provided by NSF grant(s): OCE00-01798, OCE00-01938, and OCE00-02878.本数据集依托船载导航系统（ship-based Navigation system）采集自2004年开展的W0404A号Wecoma科考航次，首席科学家为道格拉斯·威恩斯（Douglas Wiens）博士。本次数据集文件采用文本文件（ASCII）格式，包含导航数据，且已于数据采集完成后完成预处理工作。本数据采集工作作为美日联合研究项目「马里亚纳俯冲带多尺度地震成像（Multi-Scale Seismic Imaging of the Mariana Subduction Factory，简称MARIANA）」的一部分实施，研究资金由美国国家科学基金会（NSF）的OCE00-01798、OCE00-01938及OCE00-02878号资助项目提供支持。
