This data set was acquired with a ship-based BellAerospace BGM-3 Gravimeter and Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0203 conducted in 2002 (Chief Scientist: Dr. Simon Klemperer). 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): US-Japan Collaborative Research: Multi-Scale Seismic Imaging of the Mariana Subduction Factory, and funding was provided by NSF grant(s): OCE00-01798, OCE00-01938, OCE00-01956, and OCE00-02878.
