Processed near-bottom Multibeam Sonar Data (version 2) from the Lau Back-arc Basin acquired with AUV D. Allan B. during the Thomas G. Thompson expedition TN234 (2009)

This data set was acquired with a Reson SeaBat 7125 Multibeam Sonar system on the AUV D. Allan B. during Thomas G. Thompson expedition TN234 conducted in 2009 (Chief Scientist: Dr. Joseph Resing; Investigator(s): Dr. David Clague). These data files are of MBSystem-compatible format and include Sidescan, Acoustic Backscatter, and Swath Bathymetry data and were processed at sea using the open source MB-System multibeam sonar processing software. 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.

本数据集由搭载于自主水下航行器（AUV）D. Allan B.的Reson SeaBat 7125多波束声呐系统采集，采集工作依托2009年执行的Thomas G. Thompson号科考航次TN234完成（首席科学家：Joseph Resing博士；研究人员：David Clague博士）。本次采集的数据文件采用MBsystem兼容格式，涵盖侧扫声呐数据、声学背散射数据与条带测深数据，并在海上科考现场借助开源多波束声呐处理软件MB-System完成数据处理。本数据采集工作隶属于"东北劳盆地新火山活动——航次专题网页"与"北劳/汤加喷发快速响应——MARGINS"项目，相关经费由美国国家科学基金会（NSF）的OCE09-29411、OCE09-29881、OCE09-30025及OCE09-34660号资助项目提供支持。
