Southern Surveyor Voyage SS2012_T02 Multibeam Echosounder Data

Multibeam echosounder data collected on Southern Surveyor voyage SS2012_t02 using the Simrad EM300 multibeam echosounder to acquire high resolution seafloor bathymetry and backscatter information. The voyage took place from Brisbane to Lautoka, off the Queensland coast, Great Barrier Reef, Gardner Bank, and South Pacific Ocean from the 2nd May to the 10th May, 2012. Ping rate varied according to depth. Data are stored in Simrad *.all raw format at CMAR and Geoscience Australia (GA). There are 191 files totalling 3.03 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）航次SS2012_t02采集的多波束测深数据，采用西姆拉德EM300型多波束测深仪（multibeam echosounder）获取高分辨率海底地形（seafloor bathymetry）与反向散射（backscatter）信息。该航次于2012年5月2日至5月10日实施，航行路径为从布里斯班前往劳托卡，途经昆士兰州沿岸、大堡礁（Great Barrier Reef）、加德纳浅滩（Gardner Bank）及南太平洋海域。脉冲发射速率（Ping rate）随水深动态调整。数据以Simrad *.all原始格式存储于CMAR与澳大利亚地球科学局（Geoscience Australia, GA）。本数据集共计191个数据文件，原始数据总容量达3.03 GB。有关本数据集的补充信息详见该航次的航次报告及/或数据处理报告（如有公开）。
