North West Pen Llyn peninsula benthic lifeforms map.

The survey of the marine environment around the Llyn peninsula was undertaken as part of the BioMar Project which is funded by the European Community through the LIFE Programme. The area of the Llyn peninsula between South Sands at the southern mouth of the Menai Strait, southwards to Trwyn Porth-Dinllaen was surveyed between 31st May and 3 rd June 1995. Acoustic techniques were used along with biological data collected using a Towed video recorder and by scuba diving. A map of the predicted biotope distribution based on the acoustic characteristics of the Seabed was prepared for the survey area.
