Southern Surveyor Voyage SS 03/93 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“南方调查者”号科考船搭载的两套单波束回声测深数据：其一为工作频率38 kHz与120 kHz的西姆拉德EK500（Simrad EK500）单波束回声测深仪数据，其二为工作频率12 kHz的西姆拉德EA500（Simrad EA500）单波束回声测深仪数据。其中西姆拉德EK500数据主要用于水柱特性表征（涵盖鱼类种群、微型浮游生物分布调查），仅在特定场景下用于海底分类（尤其是在安装EM300条带测绘仪（EM300 swath mapper）之前的阶段）；而西姆拉德EA500数据则主要用于水深测量作业。
