MAFF DFR International 3rd Quarter Bottom Trawl Survey Data Set (1992-1997)

Surveys were primarily designed to determine the distribution and abundance of groundfish, to monitor environmental parameters and to obtain information on radiobiological pollution. The grid comprises 73 trawl positions. Temperature and salinity observations are taken at each trawl position. This survey is a continuation of the CEFAS NSGFS survey using a different gear and is part of an ICES co-ordinated programme.

本调查旨在主要确定底栖鱼类分布与丰富度，监测环境参数，并获取关于放射性生物污染的信息。调查网格包括73个拖网站位。在每个拖网站位进行温度和盐度观测。本次调查为CEFAS NSGFS调查的延续，采用不同的工具，并作为ICES协调计划的一部分。
