Southern Surveyor Voyage SS 07/97 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“南方调查号”（Southern Surveyor）科考船搭载的Simrad EK500单波束回声测深仪（single beam echosounder，38 kHz与120 kHz频段）及Simrad EA500单波束回声测深仪（single beam echosounder，12 kHz频段）采集的数据。其中，Simrad EK500单波束回声测深仪的数据主要用于水体垂直剖面特征分析，涵盖鱼类种群、微浮游生物分布研究，偶尔可用于海底分类，尤其在EM300条带测深仪（swath mapper）安装前的阶段；而Simrad EA500单波束回声测深仪的数据则主要用于水深测量。
