Southern Surveyor Voyage SS 07/2005 Single beam acoustic data

This data set contains Simrad EK500 single beam echosounder data at 38 and 120 kHz and Simrad EA500 single beam echosounder data at 12 kHz from the Southern Surveyor. The EK500 data is primarily for water column characterisation (fish stocks, microplankton distribution) and on occasions for seabed classification (particularly prior to the EM300 swath mapper being installed), while the EA500 data is primarily for bathymetric readings.本数据集包含来自“Southern Surveyor”号科考船的两类单波束回声测深数据：其一为工作频率38 kHz与120 kHz的Simrad EK500单波束回声测深仪（Simrad EK500 single beam echosounder）数据，其二为工作频率12 kHz的Simrad EA500单波束回声测深仪（Simrad EA500 single beam echosounder）数据。其中，EK500数据主要用于水体特征表征（涵盖鱼类种群、微型浮游生物分布），且在EM300条带测深仪（EM300 swath mapper）安装完成前，偶尔会被用于海底分类；EA500数据则主要用于获取水深测量数据。
