Processed ship-based Multibeam Sonar Data (ASCII format) from the Drake Passage acquired during the Nathaniel B. Palmer expedition NBP1107 (2011)

This data set was acquired with a ship-based Kongsberg EM120 Multibeam Sonar system during Nathaniel B. Palmer expedition NBP1107 conducted in 2011 (Chief Scientist: Dr. Teresa Chereskin). These data files are of ASCII format and include Swath Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): Collaborative Research: Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage, and funding was provided by NSF grant(s): ANT06-36493.

本数据集由船载Kongsberg EM120多波束声呐系统（Kongsberg EM120 Multibeam Sonar system）采集自2011年开展的内森尼尔·B·帕尔默号（Nathaniel B. Palmer）考察航次NBP1107，本次航次的首席科学家为特雷莎·切雷斯金（Teresa Chereskin）博士。本数据集文件采用ASCII格式，包含条带测深（Swath Bathymetry）数据，且均在数据采集完成后进行了后期处理。本次数据采集属于科研项目“合作研究：德雷克海峡南极绕极流动力学与输运”的一部分，并获得美国国家科学基金会（National Science Foundation，NSF）ANT06-36493号项目资助。
