Southern Surveyor Voyage SS2011_T04 Multibeam Echosounder Data

Multibeam echosounder data collected on Southern Surveyor voyage SS2011_T04 using the Simrad EM300 multibeam echosounder to acquire high resolution seafloor bathymetry and backscatter information. This voyage took place along the southern coast of Australia, from Fremantle to Hobart during November 2011, roughly following the 1000-metre contour. Ping rate varied according to depth. Data are stored in Simrad *.all raw format at CMAR and Geoscience Australia (GA). There are 230 files totalling 2.4 Gb of raw data in this dataset. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report (as available).

本数据集为“南方勘探者号”（Southern Surveyor）科考航次SS2011_T04期间采集的多波束测深声呐（multibeam echosounder）数据，使用西姆拉德EM300（Simrad EM300）多波束测深声呐获取高分辨率海底地形与反向散射信息。本次航次于2011年11月沿澳大利亚南部海岸开展，航线从弗里曼特尔（Fremantle）延伸至霍巴特（Hobart），大致沿1000米等深线布设。ping率（Ping rate）随水深变化。本数据集的数据以Simrad *.all原始数据格式存储于CMAR与澳大利亚地质调查局（Geoscience Australia, GA），共计230个原始数据文件，总容量达2.4吉字节（Gb）。有关本数据集的补充信息可查阅本次航次的航次报告及/或数据处理报告（如可获取）。
