Processed Multibeam Sonar Data (version 2) from Drake Passage and the Scotia Sea acquired during Nathaniel B. Palmer expedition NBP0805 (2008)

This data set was acquired with a Kongsberg model EM120 multibeam sonar system during Nathaniel B. Palmer expedition NBP0805 conducted in 2008 (Chief Scientist: Dr. Ian Dalziel). These data files include Sidescan, Swath Bathymetry, 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): Central Scotia Sea floor and the Drake Passage deep ocean current gateway; Glacial radiocarbon contstraints from Drake Passage deep-sea corals, 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，采集工作开展于2008年执行的纳撒尼尔·B·帕尔默（Nathaniel B. Palmer）号考察航次NBP0805（首席科学家：伊恩·达尔齐尔博士）。本次采集的数据文件涵盖侧扫声呐（Sidescan）、条带测深（Swath Bathymetry）及声学背散射（Acoustic Backscatter）数据，并采用开源MB-System多波束声呐处理软件在海上完成数据处理。本数据集的采集隶属于以下项目：斯科舍海中部海底与德雷克海峡深海洋流通道；德雷克海峡深海珊瑚的冰川放射性碳约束研究，且研究经费由美国国家科学基金会（U.S. National Science Foundation）提供资助。
