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…


Porpoises the world over: Diversity in behavior and ecology

Teilmann, Jonas; Sveegaard, Signe
Ethology and Behavioral Ecology of Odontocetes (2019)

Unlike the large number of species of true dolphins, there are only seven porpoise or phocoenid species, inhabiting different habitats and climate zones. They range from ice-covered water in the…


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

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…


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

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,…
