Southern Surveyor Voyage SS 07/2004 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.

本数据集包含源自“南探索者号”（Southern Surveyor）科考船的单波束回声测深数据，具体分为两类：其一为工作频段38 kHz与120 kHz的西姆拉德EK500（Simrad EK500）单波束回声测深数据，其二为工作频段12 kHz的西姆拉德EA500（Simrad EA500）单波束回声测深数据。其中，EK500数据主要用于水体特征表征，涵盖鱼类种群、微型浮游生物分布研究，偶尔也可用于海底分类（尤其在安装EM300条带测深仪之前）；EA500数据则主要用于获取水深测量数据。
