Field recordings of harbour porpoises (Phocoena phocoena) were made in the inner Danish waters with a vertical array of three or four hydrophones. The back-calculated source level ranged from 178…

Studies concerning the echolocation behaviour of odontocetes focus mainly on target detection and discrimination, either in stationary animals or in animals approaching a specific target. We present the first data…
Synchronized video and high-frequency audio recordings of two trained harbour porpoises searching for and capturing live fish were used to study swimming and echolocation behaviour. One animal repeated the tasks…
Herpesviruses infect a wide range of vertebrates, including toothed whales of the order Cetacea. One of the smallest toothed whales is the harbour porpoise (Phocoena phocoena), which is widespread in…
The impact of underwater noise on marine life calls for identification of exposure criteria to inform mitigation. Here we review recent experimental evidence with focus on the high-frequency cetaceans and…
The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given…
Geographic variation in the level of radioactive caesium-137 (137Cs) was examined from the axial muscle of 36 harbour porpoises Phocoena phocoena obtained as bycatch from 5 locations along the coast…
Knowledge about harbour porpoise and bottlenose dolphin occurrence in Cardigan Bay Special Area of Conservation (SAC), Wales, is limited to daylight hours during summer, when conditions are suitable for traditional…
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…
We describe the life history of harbor porpoises in the Gulf of Maine by examining 239 animals killed in gill net fisheries and comparing these findings with the results of…
