This data set was acquired with a ship-based Kongsberg EM300 Multibeam Sonar system during Thomas G. Thompson expedition TN234 conducted in 2009 (Chief Scientist: Dr. Joseph Resing). These data files are of MBSystem format and include Acoustic Backscatter, Sidescan, 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): Neovolcanic activity in the NE Lau Basin - Cruise Webpage and Northern Lau/Tonga Eruption Rapid Response - MARGINS, and funding was provided by NSF grant(s): OCE09-29411, OCE09-29881, OCE09-30025, and OCE09-34660.
