Site Description: The transect site is mainly sedimentary in nature, with scattered boulders. To the north of the site is an area dominated by boulders. The lower part of the transect site, where it borders the channel, is mud. The middle and widest section of the transect is dominated by muddy sand and gravel, with occasional lumps of clay. Scattered boulders appear along this section. The upper shore is composed of a thin layer of mud on top of gravel and pebbles. The shore top is composed of small boulders and stones. The small boulders and stones of the shore top are dominated by Pelvetia, Fucus spiralis and green algae (including Prasiola with amphipods and littorinids under the stones. The scattered boulders on the surface of the sediment are covered by Fucus vesiculosus, with some Ascophyllum, as are the boulders to the north of the site. A species search was made among the boulders on the transect, the boulder outcrop to the north, and the boulders and stones at high water. Arenicola casts (about 30 per sq. metre) occurred throughout the length of the transect, and Lanice lived on the middle and lower shore. Cockles were also present. Green algal and brown filamentous algal mats covered the sedimentary intertidal to a large extent. Nephtys and amphipods were found at all levels.
