Processed Multibeam Sonar Data (version 2) from the Ross Sea acquired during Nathaniel B. Palmer expedition NBP9801 (1998)

This data set was acquired with a SeaBeam Instruments model 2112 multibeam sonar system during Nathaniel B. Palmer expedition NBP9801 conducted in 1998 (Chief Scientist: Dr. John Anderson). These data files include 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): Timing of Retreat of the West Antarctic Ice Sheet, 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，采集工作开展于1998年执行的Nathaniel B. Palmer号科考航次NBP9801，本次航次的首席科学家为约翰·安德森博士。该批数据文件涵盖条带测深（Swath Bathymetry）与声学背散射（Acoustic Backscatter）两类数据，且已在科考作业期间通过开源MB-System多波束声呐处理软件完成数据处理。本数据集的采集隶属于"南极西部冰盖退缩时序"（Timing of Retreat of the West Antarctic Ice Sheet）研究项目，资助资金由美国国家科学基金会（U.S. National Science Foundation）提供。
