Processed Multibeam Sonar Data (version 1) near the Antarctic Peninsula acquired during Nathaniel B. Palmer expedition NBP9904 (1999)

This data set was acquired with a SeaBeam Instruments model 2112 multibeam sonar system during Nathaniel B. Palmer expedition NBP9904 conducted in 1999 (Chief Scientist: Dr. Gary Klinkhammer). These data files include Acoustic Backscatter, Sidescan, Swath Bathymetry data and were processed at sea using the open source MB-System multibeam sonar processing software. These data are included in the GMRT Synthesis, beginning with version 1. Data were acquired as part of the project(s): Multibeam Sea Test; Heat and Chemical Exchange During the Early Stages of Back-Arc Rifting in a Polar Region: Hydrothermal Activity in Bransfield Strait, Antarctica, and funding was provided by the U.S. National Science Foundation.

本数据集由SeaBeam Instruments 2112型多波束声呐系统采集，采集工作于1999年执行的内森尼尔·B·帕尔默（Nathaniel B. Palmer）号科考航次NBP9904期间完成，本次航次首席科学家为加里·克林克哈默（Gary Klinkhammer）博士。本数据集包含声学背散射数据、侧扫数据及条带测深数据，所有数据均通过开源MB-System多波束声呐处理软件完成海上处理。本数据集自第1版起便被纳入GMRT合成数据集。本次数据采集作为以下科研项目的组成部分完成：多波束海上试验；极地地区弧后裂谷早期的热与化学交换：南极布兰斯菲尔德海峡热液活动，项目资助方为美国国家科学基金会（U.S. National Science Foundation）。
