1997 - 1997 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Survey : CORY 10A/97 (part of North West Groundfish Survey, Qtr 3 (FSS: NWGFS))

This survey was undertaken by Cefas as part of the North West Groundfish Survey, Qtr 3 (FSS: NWGFS); Station, catch, length (all species) and biological data (selected species) for each of the annual surveys in the Irish Sea and Bristol Channel using research vessels and 4m beam trawls. Data mainly used to create indices of abundance in support of EU data regulations and as part of an ICES funded research program. Additional aims include collection of benthic, litter, water temperature and salinity and acoustic data. Survey took place between 15/09/1997 and 06/10/1997 on Corystes Equipment used during this survey : - Beam Trawl 4m steel commercial 3/5 link mat flip up 75mm CE 40mm liner AFT - Pumped Samples Deck Hose Nutrient samples - Vertical Profiler CTD Type 8770 Survey operations were undertaken on 186 stations 207 different species were caught on this survey本调查由英国环境、渔业与水产养殖科学中心（Centre for Environment, Fisheries and Aquaculture Science, Cefas）作为西北底层鱼类第三季度调查（FSS: NWGFS）的一部分开展。 数据集涵盖爱尔兰海与布里斯托尔湾年度各调查站位的捕捞数据、所有物种的体长数据，以及选定物种的生物学数据，本次调查采用科研船与4米桁拖网（4m beam trawl）实施。 该数据集主要用于构建种群丰度指数，以符合欧盟（European Union, EU）数据法规要求，同时作为国际海洋考察理事会（International Council for the Exploration of the Sea, ICES）资助的研究项目的组成部分。本次调查的附加目标还包括采集底栖生物、海洋垃圾、海水温度、盐度与声学数据。 本次调查于1997年9月15日至1997年10月6日期间在“科里斯特斯”号（Corystes）科研船上进行。 本次调查使用的设备如下： - 4米钢制商用桁拖网：采用3/5节网垫翻转型结构，孔径75mm，搭配40mm内衬，船尾作业（AFT） - 甲板软管泵采样本系统、营养盐样本采集装置 - 8770型CTD立式剖面仪（CTD，电导率-温度-深度仪） 本次调查共完成186个站位的采样作业。 本次调查共捕获207个不同物种。
