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.
