Cetacean monitoring is essential in determining the status of a population. Different monitoring methods should reflect the real trends in abundance and patterns in distribution, and results should therefore ideally…
Identification of high-risk areas for harbour porpoise Phocoena phocoena bycatch using remote electronic monitoring and satellite telemetry data
Kindt-Larsen, L.; Berg, C. W.; Tougaard, J.; Sørensen, T. K.; Geitner, K.; Northridge, S.; Sveegaard, S.; Larsen, F.
Marine Ecology Progress Series (2016)
The bycatch of harbour porpoise Phocoena phocoena is an issue of major concern for fisheries management and for porpoise conservation. We used high-resolution spatial and temporal data on porpoise abundance…

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…
Geographic, seasonal, and diurnal surface behavior of harbor porpoises
Teilmann, Jonas; Christiansen, Casper T.; Kjellerup, Sanne; Dietz, Rune; Nachman, Gösta
Mar Mam Sci (2012)
During ship surveys harbor porpoises are only visible when breaking the sea surface to breathe, while during aerial surveys they may be seen down to 2 m below the surface.…
Tissue healing in two harbor porpoises (Phocoena phocoena) following long-term satellite transmitter attachment
Sonne, Christian; Teilmann, Jonas; Wright, Andrew J.; Dietz, Rune; Leifsson, Pall S.
Marine Mammal Science (2011)
(...) The present note evaluates, through postmortem findings, the effect of the attachment of satellite transmitters to the dorsal fin of two wild porpoises that were later lethally bycaught in…
Spatial and temporal distribution of harbour porpoises in relation to their prey
Sveegaard, S.
Doctoral Thesis - Aarhus Universitet (2011)
The population status of harbour porpoises has been of concern for several years due to anthropogenic influences, especially incidental bycatch in gillnet fisheries. Proper management of a wide-ranging species such…
High-density areas for harbor porpoises (Phocoena phocoena) identified by satellite tracking
Sveegaard, Signe; Teilmann, Jonas; Tougaard, Jakob; Dietz, Rune; Mouritsen, Kim N.; Desportes, Geneviève; Siebert, Ursula
Marine Mammal Science (2010)
The population status of harbor porpoises has been of concern for several years, and the establishment of Marine Protected Areas (MPAs) has been suggested as a method to protect the…
Acoustic behaviour of echolocating porpoises during prey capture
DeRuiter, S. L.; Bahr, A.; Blanchet, M.-A.; Hansen, S. F.; Kristensen, J. H.; Madsen, P. T.; Tyack, P. L.; Wahlberg, M.
Journal of Experimental Biology (2009)
Porpoise echolocation has been studied previously, mainly in target detection experiments using stationed animals and steel sphere targets, but little is known about the acoustic behaviour of free-swimming porpoises echolocating…
Rehabilitation and homing behavior of a satellite-tracked harbor porpoise (Phocoena phocoena)
