BioMar survey of Lough Swilly and Mulroy Bay, County Donegal, July 1993  

E of Melmore Head, Mulroy Bay.


Dive number: 930717/03 Date: 17 July 1993

Site Description: An exposed headland near the entrance to Mulroy Bay. The seabed was a plain of course rippled sand with Echinocardium cordatum. The bedrock adjacent to the sand was colonised by Flustra foliacea, Sertularia argentea and Caryophyllia smithii. There were steep narrow gullies with Corynactis viridis growing on the walls and Urticina felina attached to the bottom. The horizontal surfaces had a rich turf of red algae, with Acrosorium uncinatum being the most conspicuous species. The vertical faces of the bedrock had a similar assemblage of species as the walls of the gullies. The kelp park extended to approximately 13 m BCD, however it probably would have gone deeper had suitable substrate been available. Echinus esculentus was abundant amongst the kelp and many of the plants had their fronds missing.
