Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW0309 (2003)

This data set was acquired with a ship-based Atlas Hydrosweep DS2 Multibeam Sonar system and BellAerospace BGM-3 Gravimeter during Maurice Ewing expedition EW0309 conducted in 2003 (Chief Scientist: Dr. JuanPablo Canales). These data files are of MGD77 format and include Gravity Field and Singlebeam Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): Seismicity, Structure, and Fluid Flow of the TAG Hydrothermal System, and funding was provided by NSF grant(s): OCE01-37329.本数据集依托2003年开展的Maurice Ewing航次EW0309（首席科学家为JuanPablo Canales博士），搭载船载Atlas Hydrosweep DS2型多波束测深声呐系统与BellAerospace BGM-3型重力仪采集获取。本次产出的数据文件均采用MGD77格式存储，包含重力场与单波束测深数据，已于数据采集完成后开展标准化数据处理工作。本数据采集工作隶属于“TAG热液系统的地震活动性、结构与流体运移”研究项目，资助方为美国国家科学基金会（National Science Foundation，NSF）的OCE01-37329号项目。
