A bedrock cliff extended from the shore to 0.7m, where there was a overhang and the cliff was slightly undercut. From 0.7m the cliff descended to 2.7m at the gully head and 6.7m at its mouth. The gully walls bore many recesses some of which formed caverns going up to 1.5m into the cliff. The floor of the gully at 2.7m sloped slightly to moderately and was predominantly large boulders. Some medium boulders and a few angular stones, rounded pebbles and patches of clean shell gravel were present. At 6.7m, the gully floor sloped slightly and was composed of medium boulders, angular stones and rounded pebbles, with one or two large boulders. There was no silt on the gully walls. The gully floor had little silt in places at 2.7m and little to moderate silt at 6.7m. Systematic animal surveys were undertaken. Plant community descriptions are based on notes of conspicuous species. Sublittoral Fringe (MSD +2.3m) Encrusting coralline algae were abundant and Alaria esculenta, Laminaria digitata and Laminaria hyperborea, were all recorded as frequent to common. Patella sp. was recorded as common. Upper Infralittoral (MSD 0.7m) The majority of observations at this depth were on the cliff beneath the dense kelp, under a slight overhang. Dense Laminaria hyperborea dominated rock surfaces between 0.7m and 2.3m. At this level Corallina sp. and Meredithia microphylla were recorded as abundant, Cryptopleura ramosa and encrusting coralline algae as common and Desmarestia aculeata was occasional. Crisiidae were common and amongst the turf Corynactis viridis and ?Salmacina dysteri/Filograna implexa were also common. Of note was the presence of Asterina phylactica (common). The sponges Stelligera rigida and Dysidea fragilis were frequent. Also frequent were Caryophyllia smithii, Balanus crenatus and Polyclinidae.
