Aquatic Mammals (2009)
Finfish aquaculture is a prominent industry in the Bay of Fundy, Canada. The distribution of harbour porpoise (Phocoena phocoena) in the Bay during the summer and fall may be impacted…
Yangtze finless porpoises along the main channel of Poyang Lake, China: Implications for conservation
Dong, Lijun; Wang, Ding; Wang, Kexiong; li, Songhai; Mei, Zhigang; Wang, Shiyong; Akamatsu, Tomonari; Kimura, Satoko
Mar Mam Sci (2014)
Poyang Lake is the largest freshwater lake in China and flows into the Yangtze River. It is a traditional habitat for the endangered Yangtze finless porpoise, which has not been…
Acoustic evidence that harbor porpoises (Phocoena phocoena) avoid bottlenose dolphins (Tursiops truncatus)
Jacobson, Eiren K.; Forney, Karin A.; Harvey, James T.
Mar Mam Sci (2014)
(...) In the present study, we investigated whether this documented conflict between bottlenose dolphins and harbor porpoises in California affected harbor porpoise behavior within the nearshore environment where habitat overlap…
Do man-made structures and water depth affect the diel rhythms in click recordings of harbor porpoises (Phocoena phocoena)?
Brandt, Miriam J.; Hansen, Sophie; Diederichs, Ansgar; Nehls, Georg
Mar Mam Sci (2014)
The construction of industrial offshore structures may lead to colonization by a variety of marine organisms resulting in locally enhanced biodiversity and biomass, which may then affect the habitat use…
Biosonar, dive, and foraging activity of satellite tracked harbor porpoises (Phocoena phocoena)
Linnenschmidt, Meike; Teilmann, Jonas; Akamatsu, Tomonari; Dietz, Rune; Miller, Lee A.
Mar Mam Sci (2012)
This study presents bioacoustic recordings in combination with movements and diving behavior of three free-ranging harbor porpoises (a female and two males) in Danish waters. Each porpoise was equipped with…
Seasonal changes in the local distribution of Yangtze finless porpoises related to fish presence
Kimura, Satoko; Akamatsu, Tomonari; Li, Songhai; Dong, Lijun; Wang, Kexiong; Wang, Ding; Arai, Nobuaki
Marine Mammal Science (2011)
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is an endangered freshwater porpoise subspecies unique to the Yangtze River basin. Seasonal variations in local distribution of the animal, as well as…
Synthetic communication signals influence wild harbour porpoise (Phocoena phocoena) behaviour
Culik, Boris; von Dorrien, Christian; Müller, Vailett; Conrad, Matthias
Bioacoustics (2015)
We used our novel and programmable Porpoise Alarm (PAL, patd.) to synthesize life-like, electronic harbour porpoise communication signals based on those described for captive animals. In the Little Belt, Denmark,…
Report of Vaquita Expedition 2008 and current conservation actions
Jaramillo-Legorreta, Armando M.; Taylor, Barb; Gerrodette, Tim; Rankin, Shannon; Swift, Rene; Rojas-Bracho, Lorenzo
Scientific Committee Meeting Documents (2009)
Two scientific efforts brought the need for immediate actions to conserve vaquita as a high priority for the Mexican government. Passive acoustic techniques (Jaramillo-Legorreta, 2008) revealed a negative trend of…
Diel echolocation activity of harbour porpoises (Phocoena phocoena) around North Sea offshore gas installations
Todd, V. L. G.; Pearse, W. D.; Tregenza, N. C.; Lepper, P. A.; Todd, I. B.
ICES Journal of Marine Science (2009)
Echolocation clicks of harbour porpoises (Phocoena phocoena) were detected with T-PODs, autonomous, passive, acoustic-monitoring devices, deployed from an offshore-exploration-drilling-rig and gas-production-platform complex in the Dogger Bank region of the North…
Noise mitigation during pile driving efficiently reduces disturbance of marine mammals
Nehls, Georg; Rose, Armin; Diederichs, Ansgar; Bellmann, Michael; Pehlke, Hendrik
Advances in Experimental Medicine and Biology (2016)
Acoustic monitoring of harbor porpoises (Phocoena phocoena L., 1758) indicated a strongly reduced disturbance by noise emitted by pile driving for offshore wind turbine foundations insulated by a big bubble…
