East Lighthouse Platform, Rathlin Island.

[Site list for year 1985]

Survey number: 555 Event number: 19850504/21 Date: 1985-05-04 GPS: 55.30200,-6.16900. Depth: 3.5 to 0.2 m. [ View map ]

Site Description: The site transect is taken across a lower shore igneous platform and upper shore igneous block scree. Between the block scree and the platform and on the platform itself are wide relatively shallow seawater inlets. These are connected to the open sea by narrow necks, and so are not treated as rock pools, but as part of the Laminaria zone. These sheltered inlets have a very good algal species diversity. The rock platforms are densely patellobarnacle, the block scree sparsely patellobarnacle, but within the block scree a small scree 10-15 square metres provides a sheltered sub habitat with typical fucoid zonation pattern. A general collection was made from this area.
