Processed Multibeam Sonar Data (version 2) from Drake Passage acquired during Nathaniel B. Palmer expedition NBP0812 (2008)

This data set was acquired with a Kongsberg model EM120 multibeam sonar system during Nathaniel B. Palmer expedition NBP0812 conducted in 2008 (Chief Scientist: Dr. Teresa Chereskin). These data files include Swath Bathymetry, Sidescan, Acoustic Backscatter 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): Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage, and funding was provided by the U.S. National Science Foundation.

本数据集由康士伯（Kongsberg）EM120型多波束声呐系统采集，采集工作于2008年执行的纳撒尼尔·B·帕尔默（Nathaniel B. Palmer）号科考航次NBP0812期间开展，首席科学家为特雷莎·切雷斯金（Teresa Chereskin）博士。本次数据集包含条带测深（Swath Bathymetry）、侧扫（Sidescan）及声学背散射（Acoustic Backscatter）数据，且已通过开源MB-System多波束声呐处理软件在海上完成数据处理。数据采集作为"德雷克海峡环南极绕极流动力学与输运"（Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage）研究项目的一部分开展，资助方为美国国家科学基金会（U.S. National Science Foundation）。
