This project examines the results of intertidal and subtidal survey of invertebrates and biotope map associated with cable to shore route at the site of the London Array offshore wind farm. Surveys of the main biotope boundaries were carried out using a Garmin GPS system with a quoted accuracy of +/- 10m. Preliminary observations on the site were made from public rights of way prior to the survey, and local knowledge was sought in order to identify potential hazards. The survey was carried out on the morning of Tuesday 28th September, on a moderately large spring tide (predicted low water 0.9m for Whitstable 07:20), by a pair of experienced intertidal biologists. Biotopes are here described according to the most recent classification available (Connor et al, 2004). Most older work has used the biotope classification version 97.06 (Connor et al, 1997).
