A comparison of benthic biodiversity in the North Sea, English Channel and Celtic Seas. Infauna grab sampling 1992-1994

Samples of the benthic macrofauna were collected from MAFF research vessels at
each of 25 intermediate and offshore stations around the English and Welsh
coastlines between 1992 and 1994. This dataset details the infauna present at
each sampling station.

At each location, five sediment samples for macrofaunal analysis were
collected using a 0.1m2 Day grab from the central point of a 500 m grid of
9 stations, the latter being sampled for contaminant analyses only. The five
replicates were collected from within a 100 m range ring, using SEXTANT
software and DGPS position-fixing.

自1992年至1994年间，本数据集详尽记录了从英国及威尔士沿岸25个中继站和海上站所采集的底栖大型无脊椎动物样本。这些样本均来自MAFF（英国农业、渔业与食品部）的研究船只。数据集详细描述了每个采样站点的底栖生物群落情况。在每个采样点，研究人员利用0.1平方米的Day抓斗，从由9个站点构成的500米网格的中心位置采集了五个沉积物样本，用于大型无脊椎动物分析。其余9个站点仅用于污染物分析。五个重复样本均在100米范围的环形区域内采集，并借助SEXTANT软件和DGPS定位技术进行定位。
