Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9904 (1999)

This data set was acquired with a ship-based Geometrics G-886 Magnetometer, BellAerospace BGM-3 Gravimeter, and Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9904 conducted in 1999 (Chief Scientist: Dr. Maya Tolstoy). These data files are of MGD77 format and include Singlebeam Bathymetry, Magnetic Field, and Gravity Field data and were processed after data collection. Data were acquired as part of the project(s): Active Seismic Imaging of Axial Volcano, and funding was provided by NSF grant(s): OCE97-11700 and OCE98-11965.
