Infaunal abundance and biomass data from surveys of the East Antrim Maerl bed in 2004

This dataset contains information on infaunal abundance and biomass from sediment grabs in Red Bay, Co. Antrim in 2004 on the RV Lough Foyle. The data from this survey was used to help support the Special Area of Conservation (SAC) site designation for Red Bay, Co. Antrim. A day grab was used to collect the samples, in total there were 20 samples taken and analysed. Particle Size Analysis (PSA) and Carbon & Nitrogen analysis was carried out on the sediments from the grab. The presence and absence of Maerl (alive or dead) was also recorded. The most abundant species found was Calcarea sp. and the most frequently recorded was the polychaete Glycera lapidium.

本数据集收录了2004年于安特里姆郡红湾，在“洛夫福德”号船上进行的沉积物抓取调查中，关于底栖生物丰度和生物量的信息。该调查数据被用于支持对安特里姆郡红湾特别保护区（SAC）的指定。采样采用日抓取法，共计采集并分析了20份样本。对抓取的沉积物进行了粒度分析（PSA）以及碳氮分析。同时，记录了马尾藻（活或死）的存在与否。发现最丰富的物种为Calcarea属，最常记录的物种为多毛类Glycera lapidium。
