Processed ship-based Multibeam Sonar Data (version 2) acquired near the Lau Back-arc Basin during the Thomas G. Thompson expedition TN236 (2009)

This data set was acquired with a ship-based Kongsberg EM300 Multibeam Sonar system during Thomas G. Thompson expedition TN236 conducted in 2009 (Chief Scientist: Dr. Anna-Louise Reysenbach). These data files are of MBSystem format and include Sidescan, Acoustic Backscatter, and Swath Bathymetry 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 2.0. Data were acquired as part of the project(s): Diversity and distribution of thermoacidophiles at deep-sea hydrothermal vents and Collaborative Research: Using thermocouple arrays to investigate temporal and spatial microbial colonization in actively forming hydrothermal vent deposits, and funding was provided by NSF grant(s): OCE07-28391, OCE07-51839, and OCE07-52469.
