Abundance and biomass of benthic infauna from mud grabs in the Irish sea as part of a mud habitat project from 2014-2015

This dataset contains information on infaunal abundance and biomass from sediment grabs from the Western Irish Sea collected in 2014 and 2015 from the RV Corystes. This survey was carried out to assess the presence, extent and the condition of subtidal mud habitats in the Western Irish Sea. A 0.1m2 day grab was used to obtain the sediment and infaunal samples. In total there were 85 grab samples taken and this was also supplemented with underwater video tows of the area for nephrops (Nephrops norvegicus) but this information is not included in this dataset. Particle Size analysis (PSA) of the sediment was also carried out along with Carbon & Nitrogen (C & N) analysis. The most abundant species found was the Bivalve Abra alba and the most frequently recorded species was the Bivalve Abra nitida.

本数据集收录2014至2015年由“科里斯特斯号”（RV Corystes）研究船在爱尔兰海西部采集的底泥抓取样品中的底栖内栖生物丰度与生物量数据。本次调查旨在评估爱尔兰海西部潮下带泥质生境的分布、覆盖范围与健康状况。研究采用0.1平方米的抓斗式采泥器采集底泥与底栖内栖生物样品。本次共获取85份抓斗采样样品，同时辅以该海域的水下视频拖曳调查以获取挪威海螯虾（Nephrops norvegicus）相关数据，但该部分信息未纳入本数据集。研究同步开展了底泥粒度分析（Particle Size Analysis, PSA）与碳氮（C & N）含量测定。本次调查中丰度最高的物种为双壳类（Bivalve）白阿布蛤（Abra alba），而记录频次最高的物种为双壳类光亮阿布蛤（Abra nitida）。
