Abundance and biomass of infaunal species as part of Essential fish habitat surveys, Co. Down Coast (Northern Ireland) 2012-2013.

This dataset contains information on infaunal abundance and biomass from sediment grab samples off the Co. Down coast in Northern Ireland as part of an Essesntial Fish Habitat (EFH) project. Essential Fish Habitat is defined as “those waters & substrata necessary to fish for spawning, breeding, feeding or growth to maturity” and these can help to form a basis for the designation of Marine Protected Areas such as Marine Conservation Zones (MCZs). This survey was carried out on the RV Corystes in 2012 and 2013 off the Co. Down coast using a 0.1m2 day grab. In 2012 there were 88 samples taken. In 2013 there were 48 samples. Infaunal analysis, Particle Size Analysis (PSA) and Carbon & Nitrogen analysis were carried out on all samples.

本数据集收录了北爱尔兰唐郡外海沉积物抓斗采样获取的底栖动物丰度与生物量相关数据，该工作作为重要鱼类栖息地（Essential Fish Habitat, EFH）项目的组成部分开展。重要鱼类栖息地被定义为“鱼类产卵、繁育、觅食以及生长至成熟所需的水域与底质环境”，此类栖息地可为海洋保护区（如海洋养护区（Marine Conservation Zones, MCZs））的划定提供核心依据。本次调查于2012年至2013年间在唐郡外海依托科里斯特斯号（RV Corystes）研究船实施，采样设备为0.1平方米抓斗。2012年共采集样品88份，2013年共采集样品48份。所有样品均完成了底栖动物分析、粒度分析（Particle Size Analysis, PSA）以及碳氮含量分析。
