Sound is the main means of communication for cetaceans, and studying their vocal behaviour can reveal important information about their activity patterns. As static acoustic monitoring (SAM) of whales, dolphins,…


Listening to echolocation clicks with PODs

Tregenza, Nick; Dawson, Steve; Rayment, Will; Verfuss, Ursula
Modern Acoustics and Signal Processing (2016)

Monitoring echolocation using SAMs—static acoustic monitors—such as T-PODs or, more recently, C-PODs—has provided a wealth of information on the fine-scale distribution and activity of dolphins, porpoises and other toothed whales.…


Effects of offshore pile driving on harbour porpoise abundance in the German Bight

Brandt, Miriam J.; Dragon, Anne-Cécile; Diederichs, Ansgar; Schubert, Alexander; Kosarev, Vladislav; Nehls, Georg; Wahl, Veronika; Michalik, Andreas; Braasch, Alexander; Hinz, Claus; Ketzer, Christian; Todeskino, Dieter; Gauger, Marco; Laczny, Martin; Pipe, Werner
Report for Offshore Forum Windenergie (2016)

This study analyses the effects of the construction of eight offshore wind farms within the German North Sea between 2009 and 2013 on harbour porpoises (Phocoena phocoena). It combines porpoise…


Harbour porpoises in the Aegean Sea, eastern Mediterranean: The species’ presence is confirmed

Cucknell, A.-C.; Frantzis, A.; Boisseau, O.; Romagosa, M.; Ryan, C.; Tonay, A. M.; Alexiadou, P.; Öztürk, A. A.; Moscrop, A.
Marine Biodiversity Records (2016)

Results are presented from the first systematic visual and acoustic line-transect survey for harbour porpoises in the Thracian Sea, northern Aegean Sea. During the vessel survey, undertaken in summer 2013,…


Comparing distribution of harbour porpoises (Phocoena phocoena) derived from satellite telemetry and passive acoustic monitoring

Mikkelsen, Lonnie; Rigét, Frank F.; Kyhn, Line A.; Sveegaard, Signe; Dietz, Rune; Tougaard, Jakob; Carlström, Julia A. K.; Carlén, Ida; Koblitz, Jens C.; Teilmann, Jonas
PLOS ONE (2016)

Cetacean monitoring is essential in determining the status of a population. Different monitoring methods should reflect the real trends in abundance and patterns in distribution, and results should therefore ideally…


Changes in click source levels with distance to targets: Studies of free-ranging white-beaked dolphins Lagenorhynchus albirostris and captive harbour porpoises Phocoena phocoena

Atem, Ana Carolina G.; Rasmussen, Marianne H.; Wahlberg, Magnus; Petersen, Hans C.; Miller, Lee A.;
Bioacoustics (2009)

Probably all odontocetes use echolocation for spatial orientation and detection of prey. We used a four hydrophone “Y” array to record the high frequency clicks from free-ranging White-beaked Dolphins Lagenorhynchus…
