Raw ship-based Multibeam Sonar Data acquired during R/V Maurice Ewing expedition EW9903 (1999)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9903 conducted in 1999 (Chief Scientist: Dr. Alistair Harding). These data files are of MBSystem Compatible format and include Acoustic Backscatter and Swath Bathymetry data that have not been processed. Data were acquired as part of the project(s): Structure of Oceanic Crust Formed at 200 mm/yr. Spreading Rate, and funding was provided by NSF grant(s): OCE98-11948 and OCE98-12612.

本数据集采集于1999年执行的莫里斯·尤因（Maurice Ewing）号科考航次EW9903，使用船载Atlas Hydrosweep DS多波束声呐系统完成数据获取，该航次首席科学家为阿利斯泰尔·哈丁博士。本数据集采用MBsystem兼容格式存储，包含未经处理的声学反向散射与条带测深数据。本次数据采集隶属于“以200毫米/年速率扩张形成的洋壳结构”研究项目，资助方为美国国家科学基金会（National Science Foundation, NSF）的两项拨款：OCE98-11948与OCE98-12612。
