Aquatic Mammals (2015)
The effects of three sonar sound types (peak frequency ca. 25 kHz with high-frequency side bands at 71 and 121 kHz) on the behavior of a harbor porpoise (Phocoena phocoena)…
Going with the flow: Tidal influence on the occurrence of the harbour porpoise (Phocoena phocoena) in the Marsdiep area, The Netherlands
IJsseldijk, Lonneke L.; Camphuysen, Kees C.J.; Nauw, Janine J.; Aarts, Geert
Journal of Sea Research (2015)
One of the most important factors explaining the distribution and behaviour of coastal marine mammals are tides. Tidal forces drive a large number of primary and secondary processes, such as…
Behavioral responses of a harbor porpoise (Phocoena phocoena) to 25.5- to 24.5-kHz sonar down-sweeps with and without side bands
Kastelein, Ronald A.; van den Belt, Ivanka; Gransier, Robin; Johansson, Torbjörn
Aquatic Mammals (2015)
Signals used in naval and long-range fish detection sonar often contain harmonics which may influence the behavior of harbor porpoises (Phocoena phocoena) more than the lower fundamental frequencies, so the…
Updated marine mammal distribution and abundance estimates in British Columbia
Best, B. D.; Fox, C. H.; Williams, R.; Halpin, P. N.; Paquet, P. C.
Journal of Cetacean Research and Management (2015)
Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out…
Cetacean noise criteria revisited in the light of proposed exposure limits for harbour porpoises
Tougaard, Jakob; Wright, Andrew J.; Madsen, Peter T.
Marine Pollution Bulletin (2015)
The impact of underwater noise on marine life calls for identification of exposure criteria to inform mitigation. Here we review recent experimental evidence with focus on the high-frequency cetaceans and…
Assessing the impact of underwater clearance of unexploded ordnance on Harbour porpoises (Phocoena phocoena) in the southern North Sea
von Benda-Beckmann, Alexander M.; Aarts, Geert; Sertlek, H. Özkan; Lucke, Klaus; Verboom, Wim C.; Kastelein, Ronald A.; Ketten, Darlene R.; van Bemmelen, Rob; Lam, Frans-Peter A.; Kirkwood, Roger J.; Ainslie, Michael A.
Aquatic Mammals (2015)
Large amounts of legacy unexploded ordnance (UXO) are still present in the North Sea. UXO are frequently accidentally encountered by fishermen and dredging vessels. Out of concern for human safety…
Quantitative measures of anthropogenic noise on harbor porpoises: Testing the reliability of acoustic tag recordings
Wisniewska, Danuta M.; Teilmann, Jonas; Hermannsen, Line; Johnson, Mark; Miller, Lee A.; Siebert, Ursula; Madsen, Peter Teglberg
The Effects of Noise on Aquatic Life II (2016)
In recent years, several sound and movement recording tags have been developed to sample the acoustic field experienced by cetaceans and their reactions to it. However, little is known about…
Pile driving playback sounds and temporary threshold shift in harbor porpoises (Phocoena phocoena): Effect of exposure duration
Kastelein, Ronald A.; Helder-Hoek, Lean; Covi, Jennifer; Gransier, Robin
The Journal of the Acoustical Society of America (2016)
High intensity underwater sounds may cause temporary hearing threshold shifts (TTSs) in harbor porpoises, the magnitude of which may depend on the exposure duration. After exposure to playbacks of pile…
Exploitation of coastal fish communities by harbour porpoises Phocoena phocoena during nursing periods in German Baltic waters
Pinzone, M.; Michel, L. N.; Gallus, A.; Brundiers, K.; Sturaro, N.; Andreasen, H.; Dähne, M.; Lepoint, G.; Siebert, U.; Das, K.; Benke, H.
Zoology Conference 2017 (2016)
The increased number of juvenile and newborn harbour porpoise strandings along the German Baltic coasts in summer provides evidence for a possible local calving and nursing ground in this area.…
Central nervous system disease and genital disease in harbor porpoises (Phocoena phocoena) are associated with different herpesviruses
van Elk, Cornelis; van de Bildt, Marco; van Run, Peter; de Jong, Anton; Getu, Sarah; Verjans, Georges; Osterhaus, Albert; Kuiken, Thijs
Veterinary Research (2016)
Herpesvirus infection causes disease of variable severity in many species, including cetaceans. However, little is known about herpesvirus infection in harbor porpoises (Phocoena phocoena), despite being widespread in temperate coastal…
