ICES Journal of Marine Science (2023)
Offshore wind energy is set to develop rapidly in waters off the east coast of the United States. There is considerable overlap between areas proposed for offshore wind development and…
Arkona offshore wind farm. Passive acoustic monitoring – Field work report.
Sveegaard, S.
(2023)
In July 2022, Aarhus University was contracted by SWECO AB to conduct a one-year baseline study and impact assessment of harbour porpoises as well as noise monitoring within the pre-investigation…
Wild harbour porpoises startle and flee at low received levels from acoustic harassment device
Elmegaard, Siri L.; Teilmann, Jonas; Rojano-Doñate, Laia; Brennecke, Dennis; Mikkelsen, Lonnie; Balle, Jeppe D.; Gosewinkel, Ulrich; Kyhn, Line A.; Tønnesen, Pernille; Wahlberg, Magnus; Ruser, Andreas; Siebert, Ursula; Madsen, Peter Teglberg
Scientific Reports (2023)
Acoustic Harassment Devices (AHD) are widely used to deter marine mammals from aquaculture depredation, and from pile driving operations that may otherwise cause hearing damage. However, little is known about…
Marine mammal sightings around oil and gas installations in the central North Sea
Delefosse, Matthieu; Rahbek, Malene Louise; Roesen, Lars; Clausen, Karin Tubbert
Journal of the Marine Biological Association of the United Kingdom (2017)
Relatively little is known about the distribution and diversity of marine mammals around offshore anthropogenic structures. We present results obtained from incidental sightings of marine mammals around oil and gas…
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…
Marine noise budgets in practice
Merchant, Nathan D.; Faulkner, Rebecca C.; Martinez, Roi
Conservation Letters (2017)
Many countries have made statutory commitments to ensure that underwater noise pollution is at levels which do not harm marine ecosystems. Nevertheless, coordinated action to manage cumulative noise levels is…
Conservation plan for the harbour porpoise Phocoena phocoena in The Netherlands: Towards a favourable conservation status
Camphuysen, Kees C. J.; Siemensma, Marije L.
NIOZ Reports (2011)
- This is a conservation plan for the Harbour Porpoise Phocoena phocoena based on the current seasonal occurrence and abundance of porpoises within waters under Dutch jurisdiction. - The conservation…
Return of harbor porpoises (Phocoena phocoena) to San Francisco Bay
Stern, S. Jonathan; Keener, William; Szczepaniak, Isidore D.; Webber, Marc A.
Aquatic Mammals (2017)
Harbor porpoises (Phocoena phocoena) were rarely seen in San Francisco Bay prior to 2008 despite numerous marine mammal search efforts beginning in the 1970s. The species inhabited the bay historically…
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…

Han, Yong; Sun, Zhiyu; Fang, Hongwei; Bai, Sen; Huang, Lei; He, Guojian
Ecological Modelling (2020)
Poyang Lake, located in the middle and lower reaches of the Yangtze River, is the largest freshwater lake in China and the most important habitat for the Yangtze finless porpoise.…
