Behavioral reactions of harbor porpoise to pile-driving noise
Tougaard, Jakob; Kyhn, Line A.; Amundin, Mats; Wennerberg, Daniel; Bordin, Carolina
Advances in Experimental Medicine and Biology (2012)
Pile driving of large steel monopiles in offshore waters has increased rapidly in recent years due to the expanding development of offshore wind energy. In particular, Phocoena phocoena (harbor porpoise)…
Asymmetry and dynamics of a narrow sonar beam in an echolocating harbor porpoise
Koblitz, Jens C.; Wahlberg, Magnus; Stilz, Peter; Madsen, Peter T.; Beedholm, Kristian; Schnitzler, Hans-Ulrich
The Journal of the Acoustical Society of America (2012)
A key component in the operation of a biosonar system is the radiation of sound energy from the sound producing head structures of toothed whales and microbats. The current view…

From echolocation clicks to animal density—Acoustic sampling of harbor porpoises with static dataloggers
Kyhn, Line A.; Tougaard, Jakob; Thomas, Len; Duve, Linda Rosager; Stenback, Joanna; Amundin, Mats; Desportes, Geneviève; Teilmann, Jonas
The Journal of the Acoustical Society of America (2012)
Monitoring abundance and population trends of small odontocetes is notoriously difficult and labor intensive. There is a need to develop alternative methods to the traditional visual line transect surveys, especially…

Larrat, Sylvain; Measures, Lena N.; Lair, Stéphane;
Aquatic Mammals (2012)
(...) Little is known regarding other causes of mortality and population trends of harbor porpoises from the Estuary and Gulf of St. Lawrence. Harbor porpoises have been reported to be…
Swimming patterns of wild harbour porpoises Phocoena phocoena show detection and avoidance of gillnets at very long ranges
Nielsen, T.P.; Wahlberg, M.; Heikkilä, S.; Jensen, M.; Sabinsky, P.; Dabelsteen, T.
Marine Ecology Progress Series (2012)
Harbour porpoises Phocoena phocoena are unintentionally caught in gillnets. Although the effectiveness of by-catch mitigation measures has been evaluated many times, only a few studies have investigated the behavioural patterns…
