Raw ship-based Multibeam Sonar Data from the Central America Subduction Zone acquired during R/V Maurice Ewing expedition EW0104 (2001)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW0104 conducted in 2001 (Chief Scientist: Dr. Andrew Fisher). These data files are of MBSystem Compatible format and include Acoustic Backscatter and Swath Bathymetry data that have not been processed. These data are included in the GMRT Synthesis, version 1. Data were acquired as part of the project(s): TicoFlux I: The Thermal State of 20-25 Ma Lithosphere Subducting at the Costa Rica Margin, Implications for Hydrogeology, Fluxes, and the Seismogenic Zone, and funding was provided by NSF grant(s): OCE00-01892, OCE00-01941, OCE00-01944, and OCE00-02031. This data was cited by Hutnak et al., 2007.
