Robin's Rock, Outer Ards.

Survey number: 555 Event number: 19860407/21 Date: 1986-04-07 GPS: 54.47383,-5.43900. Depth: 3.5 to 0.2 m. [ View map ]

Site Description: The transect was taken across a long sandstone platform (not sharp ridges), one of several lying along the seaward edge of a sandy bay. The platform is patellobarnacle dominated along most of its length, but the inner margin is more sheltered, clothed in a dense growth of fucoids, mainly Ascophyllum. Rock pools on the platform support a high algal diversity.
