Processed Multibeam Sonar Data (version 2) from the Drake Passage acquired during Nathaniel B. Palmer expedition NBP1004 (2010)

This data set was acquired with a Kongsberg model EM120 multibeam sonar system during Nathaniel B. Palmer expedition NBP1004 conducted in 2010 (Chief Scientist: Dr. Teresa Chereskin). 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. Data were acquired as part of the project(s): Drake Passage Current and Pressure Recording Inverted Echo Sounders (CPIES), and funding was provided by the U.S. National Science Foundation.

本数据集采用康斯伯格（Kongsberg）EM120型多波束声呐系统采集，采集工作依托2010年执行的内森尼尔·B·帕尔默（Nathaniel B. Palmer）号科考航次NBP1004完成，该航次首席科学家为特蕾莎·切雷斯金（Teresa Chereskin）博士。本次数据文件涵盖声学背散射（Acoustic Backscatter）、侧扫（Sidescan）与条带测深（Swath Bathymetry）三类数据，并依托开源多波束声呐处理软件MB-System完成海上数据处理。本数据集为德雷克海峡海流与压力记录式倒置回声测深仪（Drake Passage Current and Pressure Recording Inverted Echo Sounders，CPIES）项目的组成部分，项目资助方为美国国家科学基金会（U.S. National Science Foundation）。
