Mid Island Bay, Strangford Lough.
Survey number: 555 Event number: 19860629/21 Date: 1986-06-29 GPS: 54.45400,-5.54300. Depth: 3.5 to 0.2 m. [ View map ]
Site Description: The transect was taken across one of the long low sandstone ridge outcrops embedded in muddy sand which are typical of Mid Island Bay. The outcrop does not reach down to low water mark, and no part of it extends into the higher intertidal. Consequently only 2 biological zones are present on the outcrop; most of it dominated by Ascophyllum, with a fringe of Fucus serratus. The surface of the outcrop is covered by sediment, mainly mud bound by Rhodothamniella floridula (originally recorded as Audouinella floridula). There are some ridge rock pools and pockets of muddy sand and mud between ridges. There is a small boulder area in the Ascophyllum zone.
