Marine Geoscience Data System
EW9407 Bathymetry:Singlebeam, Gravity:Field, Magnetic:Field
Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9407 (1994)
This data set was acquired with a ship-based Varian Inc. V75 Magnetometer, BellAerospace BGM-3 Gravimeter, and Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9407 conducted in 1994 (Chief Scientist: Dr. Anne Meltzer). These data files are of MGD77 format and include Gravity Field, Magnetic Field, and Singlebeam Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): Lithospheric Evolution in Response to Triple Junction Migration: Seismic Images of the Mendocino Triple Junction Region, and funding was provided by NSF grant(s): EAR92-18209, EAR92-18968, EAR92-19598, EAR92-19870, EAR95-26116, EAR95-26258, EAR95-26963, and EAR95-27001.
