Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW0501 (2005)

This data set was acquired with a ship-based BellAerospace BGM-3 Gravimeter and Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0501 conducted in 2005 (Chief Scientist: Dr. Sean Gulick). 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): Imaging and Modeling Impact Generated Deformation at the Chicxulub Crater, Joint US/UK/Mexico Investigation and IODP Site Survey and 3D Tomographic Imaging of the Chicxulub Crater, and funding was provided by NSF grant(s): OCE02-20474 and OCE02-21101.
