The use of waters around Lundy by dolphins and porpoises was measured using summer shore-based watches and passive acoustic surveillance between July 2011 and July 2012. Common dolphins (Delphinus delphis) were the only cetacean species observed during shore-based surveys. C-PODs moored on the Ethel and MV Robert wrecks close to the Lundy coast showed a peak in delphinid vocal activity during August 2011. Passive acoustic detections of harbour porpoises (Phocoena phocoena) were highest during ebb tidal phases and most often associated with the tidal rip at the south of the island. These findings show tidal and monthly influences on odontocete behaviour and highlight the value of continuous, passive acoustic monitoring for these highly mobile marine predators around Lundy.
