Southern Surveyor Voyage SS 04/92 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.

本数据集收录了搭载于“南方勘测号”（Southern Surveyor）科考船的两款单波束回声测深仪数据：分别为工作频率38 kHz与120 kHz的Simrad EK500型单波束回声测深仪（Simrad EK500 single beam echosounder）数据，以及工作频率12 kHz的Simrad EA500型单波束回声测深仪（Simrad EA500 single beam echosounder）数据。其中，EK500数据主要用于水体特征表征（涵盖鱼类种群调查、微型浮游生物分布研究），仅在特定场景下（尤其是安装EM300条带测深仪（EM300 swath mapper）之前）用于海底底质分类；而EA500数据则主要用于水深测量。
