Abundance and Biomass of infaunal species from grab samples from a benthic assessment for Fair Head tidal energy development site (Fair Head, Co. Antrim), 2014.

This dataset contains information on infaunal abundance & biomass from sediment grab samples and video tows carried out off the coast of Fair Head (Co. Antrim) on the FPV Banríon Uladh (now Queen of Ulster). This survey was carried out to provide a benthic baseline for a potential offshore windfarm development site in May 2014. The main aim of this survey was to undertake a baseline assessment of the species & biotopes found in the area of interest. The survey comprised of 26 video stations and 10 grab stations (3 repeats per station) with 24 samples retained for infaunal analysis- the abundance & biomass was recorded. Particle size analysis (PSA) was also carried out but due to low success rate of grab samples, only 4 samples were appropriate for this analysis. The most abundant infauna found was Ascidiacea.

本数据集涵盖了在安特里姆郡费尔黑德近海、由“阿尔斯特女王号”（FPV Banríon Uladh，现更名Queen of Ulster）开展的沉积物取样器采样与视频拖曳采样所获取的底内生物（infauna）丰度与生物量数据。本次调查于2014年5月开展，旨在为一处潜在海上风电场开发场址建立底栖生物基线数据。本次调查的核心目标为对目标海域内发现的物种与生物群落生境开展基线评估。本次调查共设置26个视频采样站位与10个沉积物取样器采样站位（每个站位设置3次重复采样），其中留存24份样本用于底内生物分析，并记录了其丰度与生物量。本次调查同时开展了粒度分析（Particle Size Analysis, PSA），但由于沉积物取样器采样成功率较低，仅4份样本符合该分析的要求。本次调查发现的丰度最高的底内生物为海鞘纲（Ascidiacea）。
