High rates of vessel noise disrupt foraging in wild harbour porpoises (Phocoena phocoena)

Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Siebert, Ursula; Galatius, Anders; Dietz, Rune; Madsen, Peter Teglberg
Proceedings of the Royal Society B: Biological Sciences (2018)

Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild,…


Acoustic monitoring reveals the times and tides of harbor porpoise (Phocoena phocoena) distribution off central Oregon, U.S.A.

Holdman, Amanda K.; Haxel, Joseph H.; Klinck, Holger; Torres, Leigh G.
Marine Mammal Science (2018)

Harbor porpoises (Phocoena phocoena) are commonly observed in Oregon's nearshore marine environment yet knowledge of their ecosystem use and behavior remains limited, generating concerns for potential impacts on this species…


Bubble curtains attenuate noise from offshore wind farm construction and reduce temporary habitat loss for harbour porpoises

Dähne, M.; Tougaard, J.; Carstensen, J.; Rose, A.; Nabe-Nielsen, J.
Marine Ecology Progress Series (2017)

Effects of constructing the DanTysk offshore wind farm (German Bight, 80 turbines, 6 m diameter foundations) were studied by passive acoustic monitoring of pile-driving noise and harbour porpoise Phocoena phocoena…


Time and tide: Seasonal, diel and tidal rhythms in Wadden Sea harbour porpoises (Phocoena phocoena)

Zein, Beate; Woelfing, Benno; Dähne, Michael; Schaffeld, Tobias; Ludwig, Stefan; Rye, Jacob Hansen; Baltzer, Johannes; Ruser, Andreas; Siebert, Ursula
PLOS ONE (2019)

Odontocetes have evolved a rich diversity of prey- and habitat-specific foraging strategies, which allows them to feed opportunistically on locally and temporally abundant prey. While habitat-specific foraging strategies have been…

Fang, Liang; Wang, Ding; Li, Yongtao; Cheng, Zhaolong; Pine, Matthew K.; Wang, Kexiong; Li, Songhai
PLOS ONE (2015)

The clicks of Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) from 7 individuals in the tank of Baiji aquarium, 2 individuals in a netted pen at Shishou Tian-e-zhou Reserve and 4…


Harbor porpoise (Phocoena phocoena) reaction to a 3D seismic airgun survey in the North Sea

Sarnocińska, Joanna; Teilmann, Jonas; Balle, Jeppe Dalgaard; van Beest, Floris M.; Delefosse, Matthieu; Tougaard, Jakob
Frontiers in Marine Science (2020)

The most common cetacean in the North Sea is the harbor porpoise (Phocoena phocoena). Underwater noise is increasingly recognized as a source of impact on the marine environment and seismic…
