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.

本数据集涵盖费尔黑德（安特里姆郡）外海FPV Banríon Uladh（现名“乌尔斯特女王号”）作业期间，通过沉积物抓取采样与视频拖曳采样获取的底内生物丰度与生物量相关数据。本次调查于2014年5月实施，旨在为一处潜在海上风电场开发场址建立底栖基线数据。本次调查的核心目标是对目标区域内的物种与生物群落生境开展基线评估。调查共布设26个视频采样站位与10个沉积物抓取采样站位（每个站位设置3次重复采样），最终留存24份样本用于底内生物分析，并记录了对应样本的丰度与生物量。此外还开展了粒度分析（Particle Size Analysis, PSA），但受限于沉积物抓取采样的低成功率，仅4份样本符合该分析的适用要求。本次调查中丰度最高的底内生物类群为海鞘纲（Ascidiacea）。
