Mammal Study (2019)
Studies on odontocetes (e.g., porpoises) have revealed that these animals may adaptively use vision. The present study examined the contributions of vision to the approaching behavior of the harbor porpoise…
High levels of food intake in harbor porpoises (Phocoena phocoena): Insight into recovery from disturbance
Kastelein, Ronald A.; Helder-Hoek, Lean; Booth, Cormac; Jennings, Nancy; Leopold, Mardik
Aquatic Mammals (2019)
If harbor porpoises (Phocoena phocoena) are impaired in their foraging ability because they need to move away from anthropogenic sound sources, their fitness may be reduced. Understanding how much harbor…
Using reflected clicks to monitor range and depth of Atlantic harbour porpoises
Sanderson, B.; Adams, M.; Redden, A.
The Journal of Ocean Technology (2019)
Detection of the time of arrival of a harbour porpoise click at several synchronized broadband hydrophones, attached to a drifter, provides a method for locating porpoise and assessing any interactions…
Unexpected mid‐winter presence of harbor porpoises (Phocoena phocoena) in Kotzebue Sound, Alaska
Whiting, Alex; Castellote, Manuel; Small, Robert J.; Frost, Kathryn J.; Suydam, Robert
Marine Mammal Science (2019)
...Harbor porpoises have been reported as an uncommon species in Kotzebue Sound during the ice-free months of June through October (Frost & Lowry, 1990), but their presence in Kotzebue Sound…
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…
Modelling fine-scale distribution and relative abundance of harbour porpoises in the Southern Bight of the North Sea using platform-of-opportunity data
Bouveroux, Thibaut; Waggitt, James J.; Belhadjer, Anissa; Cazenave, Pierre W.; Evans, Peter G.H.; Kiszka, Jeremy J.
Journal of the Marine Biological Association of the United Kingdom (2020)
Over the last 25 years, the harbour porpoise (Phocoena phocoena) has made a significant return to the Southern Bight of the North Sea and the English Channel due to a…
Contextual impacts on individual and synchronous breathing rate variations in three captive odontocete groups
Serres, Agathe; Hao, Yujiang; Wang, Ding
Zoo Biology (2020)
Breathing rates are often collected both in the wild and in captivity to inform on cetaceans' internal state. However, few studies have investigated the effect of various factors on this…
Effects of multiple exposures to pile driving noise on harbor porpoise hearing during simulated flights—An evaluation tool
Schaffeld, Tobias; Schnitzler, Joseph G.; Ruser, Andreas; Woelfing, Benno; Baltzer, Johannes; Siebert, Ursula
The Journal of the Acoustical Society of America (2020)
Exploitation of renewable energy from offshore wind farms is substantially increasing worldwide. The majority of wind turbines are bottom mounted, causing high levels of impulsive noise during construction. To prevent…
Modeling of the near to far acoustic fields of an echolocating bottlenose dolphin and harbor porpoise
Wei, Chong; Au, Whitlow W. L.; Ketten, Darlene R.
The Journal of the Acoustical Society of America (2020)
Echolocation signals emitted by odontocetes can be roughly classified into three broad categories: broadband echolocation signals, narrowband high-frequency echolocation signals, and frequency modulated clicks. Previous measurements of broadband echolocation signal…
Harbor porpoises (Phocoena phocoena vomerina) catching and handling large fish on the U.S. west coast
Elliser, Cindy R.; Hessing, Sanne; MacIver, Katrina H.; Webber, Marc A.; Keener, William
Aquatic Mammals (2020)
...This short note documents instances of prey handling and consumption of large fish species along the West Coast of the United States (U.S.), including the Salish Sea (inland waters of…
