Southern Surveyor Voyage SS 05/2006 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“南方调查号”（Southern Surveyor）科考船的两类单波束回声测深数据：其一为38 kHz与120 kHz频段的Simrad EK500单波束回声测深仪数据，其二为12 kHz频段的Simrad EA500单波束回声测深仪数据。其中，EK500数据主要用于水柱特性表征（鱼类种群、微浮游生物分布），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。
