Processed ship-based Multibeam Sonar Data (version 2) acquired at the Juan de Fuca Spreading Center during the Atlantis expedition AT18-08 (2011)
This data set was acquired with a ship-based Kongsberg EM122 Multibeam Sonar system during Atlantis expedition AT18-08 conducted in 2011 (Chief Scientist: Dr. William Chadwick). These data files are of MBSystem format and include Sidescan, Swath Bathymetry, and Acoustic Backscatter data and were processed by the GMRT Team using the open source MB-System multibeam sonar processing software as part of the GMRT Synthesis effort. These data are included in the GMRT Synthesis, version 2.3. Data were acquired as part of the project(s): NeMO 2011 - Axial Seamount and Endeavour Segment, Collaborative Research: Monitoring inflation at Axial Seamount, Collaborative Research: Thermal biology of hydrothermal vent paralvinellid worms, Resistivity Probe Deployments at the Endeavour ISS, and Essential upgrades to resistivity instruments, and funding was provided by NSF grant(s): OCE06-23383, OCE06-23554, OCE07-25605, OCE07-26093, OCE07-51868, and OCE08-19004.
