This paper describes a rare sighting of an anomalously white harbour porpoise (Phocoena phocoena) in the coastal waters of the outer Moray Firth in north-east Scotland. The recording provides the…
Unusual mortality events of harbor porpoise strandings in North Carolina, 1997–2009
Hohn, Aleta A.; Rotstein, David S.; Byrd, Barbie L.
Journal of Marine Biology (2013)
A marked increase in the frequency of harbor porpoises (Phocoena phocoena) stranded in North Carolina in 2005 was declared as an Unusual Mortality Event (UME). Strandings occurred in January through…
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…
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…
The possible reasons for bottlenose dolphins (Tursiops truncatus) participating in non-predatory aggressive interactions with harbour porpoises (Phocoena phocoena) in Cardigan Bay, Wales
Neale, Leonora
Honour's Thesis - University of Nottingham (2013)
Between 1991 and 2011, 137 harbour porpoises (Phocoena phocoena) died as a result of attacks by bottlenose dolphins (Tursiops truncatus) in Cardigan Bay. The suggested reasons for these non-predatory aggressive…
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…
The stranding anomaly as population indicator: The case of harbour porpoise Phocoena phocoena in North-Western Europe
Peltier, Helene; Baagøe, Hans J.; Camphuysen, Kees C. J.; Czeck, Richard; Dabin, Willy; Daniel, Pierre; Deaville, Rob; Haelters, Jan; Jauniaux, Thierry; Jensen, Lasse F.; Jepson, Paul D.; Keijl, Guido O.; Siebert, Ursula; Van Canneyt, Olivier; Ridoux, Vincent
PLoS ONE (2013)
Ecological indicators for monitoring strategies are expected to combine three major characteristics: ecological significance, statistical credibility and cost-effectiveness. Strategies based on stranding networks rank highly in cost-effectiveness, but their ecological…

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…
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…
