Survey carrried out by the NRA as part of a long term monitoring programme (1974 - 1982 for these sites). Sublittoral sediments were sampled using a 0.1 m^2 Day Grab and two replicates were taken at each site. The data for the 1981 survey has been input as it represents the most recent of the data sets from the monitoring programme with all the sampling information present. Faunal data is available for a 1982 survey but there is no granulometric data or sediment description. All grid references have been approximated using the map provided in the report. For faunal data for the same sites in previous years see report by David Lowthion, 1982. (R2278).
