In the southern North Sea, hundreds of mutilated harbour porpoise carcasses (Phocoena phocoena) are found each year on beaches. Recent studies have confirmed that these concern the remains of predation…
Group characteristics, site fidelity, and photo-identification of harbor porpoises, Phocoena phocoena, in Burrows Pass, Fidalgo Island, Washington
Elliser, Cindy R.; MacIver, Katrina H.; Green, Michelle
Marine Mammal Science (2017)
Little is known about harbor porpoises at the individual level or local group structure. Group characteristics, site fidelity, and photo‐identification of harbor porpoises were investigated off Fidalgo Island, Washington State.…
Temporary hearing threshold shift in a harbor porpoise (Phocoena phocoena) after exposure to multiple airgun sounds
Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; von Benda-Beckmann, Alexander M.; Lam, Frans-Peter A.; Jansen, Erwin; de Jong, Christ A. F.; Ainslie, Michael A.
The Journal of the Acoustical Society of America (2017)
In seismic surveys, reflected sounds from airguns are used under water to detect gas and oil below the sea floor. The airguns produce broadband high-amplitude impulsive sounds, which may cause…

Aquatic Mammals (2017)
Harbor porpoises (Phocoena phocoena) were rarely seen in San Francisco Bay prior to 2008 despite numerous marine mammal search efforts beginning in the 1970s. The species inhabited the bay historically…
