Description 
Summary

A set of approximately 40 stations, extending from Weston-Super-Mare (in the Bristol Channel) around the coast to the Isle of Wight (English Channel) was investigated each spring. About 20 of those in Devon, Cornwall and Dorset, were looked at each year from 1954 to 1987. The earlier observations were counts of barnacle abundance, then limpets were added. After the 'Torrey Canyon' spill in 1967 the data set was enlarged to cover other abundant organisms, including seaweeds and mussels, but on an intermittent basis and concentrating on the Cornish stations. The data are held in notebooks, but most of them have been transferred to Database 3/Paradox compatible files on PC. The barnacle data only were transferred to a Lotus 123 compatible spreadsheet, and edited averages are held in main-frame computer files. There is a semi-quantitative baseline for some stations dated 1930. A group of stations, five then four, around Plymouth were surveyed for the barnacles in greater detail each autumn from 1951 to 1987; then one station has been continued to date. There is a baseline survey going back to 1934. One station has been entered onto a PC (Word Processor) and this has been published (Southward 1991).
