Proceedings of Meetings on Acoustics (2012)
Offshore wind farms (OWF) will soon contribute to significant growth in the renewable energy sector. At present just a few OWF have been built. As of 2012, Germany has an…
Brief behavioral response threshold level of a harbor porpoise (Phocoena phocoena) to an impulsive sound
Kastelein, Ronald; Steen, Nele; Gransier, Robin; de Jong, Christ A. F.
Aquatic Mammals (2013)
Underwater impulsive sounds may affect the behavior of harbor porpoises within a certain distance from the sound source. To determine the 50% threshold received sound exposure level (SEL) of an…
Possible causes of a harbour porpoise mass stranding in Danish waters in 2005
Wright, Andrew J.; Maar, Marie; Mohn, Christian; Nabe-Nielsen, Jacob; Siebert, Ursula; Jensen, Lasse Fast; Baagøe, Hans J.; Teilmann, Jonas
PLoS ONE (2013)
An unprecedented 85 harbour porpoises stranded freshly dead along approximately 100 km of Danish coastline from 7–15 April, 2005. This total is considerably above the mean weekly stranding rate for…
Effects of pile-driving on harbour porpoises (Phocoena phocoena) at the first offshore wind farm in Germany
Dähne, Michael; Gilles, Anita; Lucke, Klaus; Peschko, Verena; Adler, Sven; Krügel, Kathrin; Sundermeyer, Janne; Siebert, Ursula
Environ. Res. Lett. (2013)
The first offshore wind farm 'alpha ventus' in the German North Sea was constructed north east of Borkum Reef Ground approximately 45 km north off the German coast in 2008…

Journal of the Marine Biological Association of the United Kingdom (2013)
The Istanbul Strait (Bosphorus) is a part of the Turkish Straits System, connecting the Aegean Sea and the Black Sea. There are three cetacean species in the Strait, namely the…
Determining optimal pinger spacing for harbour porpoise bycatch mitigation
Larsen, F.; Krog, C.; Ritzau Eigaard, O.
Endangered Species Research (2013)
A trial was conducted in the Danish North Sea hake gillnet fishery in July to September 2006 to determine whether the spacing of the Aquatec AQUAmark100 pinger could be increased…
Echolocation by the harbour porpoise: life in coastal waters
Miller, Lee A.; Wahlberg, Magnus
Frontiers in Physiology (2013)
The harbor porpoise is one of the smallest and most widely spread of all toothed whales. They are found abundantly in coastal waters all around the northern hemisphere. They are…
To ping or not to ping: The use of active acoustic devices in mitigating interactions between small cetaceans and gillnet fisheries
Dawson, S. M.; Northridge, S.; Waples, D.; Read, A. J.
Endangered Species Research (2013)
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how…
Brief behavioral response threshold levels of a harbor porpoise (Phocoena phocoena) to five helicopter dipping sonar signals (1.33 to 1.43 kHz)
Kastelein, Ronald; Gransier, Robin; van den Hoogen, Marjan; Hoek, Lean
Aquatic Mammals (2013)
Helicopter Long Range Active Sonar (HELRAS) is deployed from navy helicopters to detect submarines. Its worldwide use by NATO navies is expected to increase due to the increasing need to…
Using pingers to reduce bycatch of small cetaceans in Peru’s small-scale driftnet fishery
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Witt, Matthew J.; Hodgson, David J.; Godley, Brendan J.
Oryx (2013)
There is growing awareness that small-scale fisheries may have large impacts on threatened marine fauna. Bycatch of small cetaceans by the Peruvian small-scale driftnet fleet results in the deaths of…
