Southern Surveyor Voyage SS2009_V05 Multibeam Echosounder Data

Multibeam echosounder data collected on Southern Surveyor voyage ss2009_v05 using the Simrad EM300 multibeam echosounder to acquire high resolution seafloor bathymetry and backscatter information. This voyage took place off NSW during October 2009. Ping rate varied according to depth. Data are stored in Simrad *.all raw format at CMAR and Geoscience Australia (GA). There are 249 files totalling 4.95 GB of raw data in this dataset. Data was collected in auto mode and only one sound velocity profile was updated on the last day of data collection.

本数据集为“南测者号”（Southern Surveyor）科考航次ss2009_v05期间采集的多波束测深声呐（multibeam echosounder）数据，采用Simrad EM300多波束测深声呐系统获取高分辨率海底地形测深与反向散射信息。本次航次于2009年10月在新南威尔士州（New South Wales，NSW）外海开展。声呐脉冲发射频率（ping rate）随水深动态调整。数据以Simrad *.all原始格式存储于CMAR及澳大利亚地质调查局（Geoscience Australia, GA）。本数据集共计249个文件，总原始数据量达4.95吉字节。所有数据以自动模式采集，仅在数据采集最后一日更新了一次声速剖面（sound velocity profile）。
