For this reason, extensive sighting surveys to assess their distribution, abundance, and habitat preference are needed. In this study, we conducted systematic surveys to document the distribution of the harbor porpoise observed in the English Channel (North Sea, France). The English Channel is an epicontinental sea. It constitutes a relatively narrow link between the Atlantic Ocean and the North Sea and is influenced by strong tides and freshwater inputs, which create well-mixed waters. The harbor porpoise is placed under Appendix II of the European Union Habitats Directive, and an assessment of his status and distribution in the English Channel, very exposed to human activities, is much needed to identify conservation and management strategies.<br><br> Therefore, we conducted surveys following a series of predetermined saw-tooth transect lines to study the distribution of the harbor porpoise (<i>Phocoena phocoena</i>). Boat transect were conducted using a Sealine Stateman 35, equipped with two 230 hp Volvo inboard engine at speed around 10 knots. Surveys were made as many days as possible throughout the season at sea state of Beaufort 3 or less, between March 2009 and September 2011.<br><br> For each animal sighting, the species, angle of sighting, the distance from the boat, the group size and composition, the general behavior and the swimming direction were recorded.
