EW0501 Navigation:Primary

Shapefile of Processed ship-based Navigation Data acquired during the Maurice Ewing expedition EW0501 (2005)

This data set was acquired with a ship-based Navigation system during Maurice Ewing expedition EW0501 conducted in 2005 (Chief Scientist: Dr. Sean Gulick). These data files are of Shapefile format and include Navigation 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.
