Southern Surveyor Voyage SS 05/94 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.

本数据集包含来自南方调查船（Southern Surveyor）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（Simrad）EK500单波束回声测深仪（single beam echosounder）数据，其二为工作频率12 kHz的西姆拉德（Simrad）EA500单波束回声测深仪数据。其中EK500数据主要用于水柱特征表征，涵盖鱼类种群、微型浮游生物分布研究，偶用于海底分类（尤其在安装EM300条带测深仪之前）；EA500数据则主要用于水深测量。
