Ardglass Bay (rock), SE Coast.

[Site list for year 1985]

Survey number: 555 Event number: 19851019/21 Date: 1985-10-19 GPS: 54.26283,-5.60700. Depth: 3.5 to 0.2 m. [ View map ]

Site Description: The site consists of rock ridge outcrops interrupted by small boulders and stones on the lower shore, and by muddy gravel, muddy sand and stones on the upper shore. Much of the rock is sediment covered. The rock ridges on the upper shore are fucoid dominated mainly by Ascophyllum. However, on the lower shore only the areas between the ridges are fucoid dominated, with the ridge tops themselves dominated by barnacles, limpets and Nucella. There was a poor tide on the sampling date. The most prominent sub habitats were a number of wide, shallow rock pools in zone 4, which had a good animal and algal diversity. Zone 5 was partially submerged on arrival, and may be richer than the results indicate. Wading revealed a lower zone of patchy Saccharina latissima (originally recorded as Laminaria saccharina).
