Scientific Committee Meeting Documents (2015)
The Expert Panel on Vaquita Acoustic Monitoring had its second meeting on April 28, 2015 to analyze the first four seasons (2011-2014) of the acoustic monitoring program. Results indicate an…
Acoustic signals of the pilot whale Globicephala melaena and of the porpoises Delphinus delphis and Phocoena phocoena
Busnel, R.-G.; Dziedzic, A.
Whales, Dolphins, and Porpoises [Proceedings] (1966)
(...) Some of the observations mentioned in this paper have been made at sea, on board the oceanographic vessel Calypso, put at our disposal by a special committee of the…
Pingers cause temporary habitat displacement in the harbour porpoise Phocoena phocoena
Kyhn, L. A.; Jørgensen, P. B.; Carstensen, J.; Bech, N. I.; Tougaard, J.; Dabelsteen, T.; Teilmann, J.
Marine Ecology Progress Series (2015)
Several studies have shown that pingers mitigate porpoise bycatch and thus pinger use is now mandatory in some fisheries—although the long-term effects of pinger exposure on porpoises have not been…
Effects of the Horns Reef Wind Farm on harbour porpoises
Tougaard, J.; Teilmann, J.; Hansen, J. R.
Interim Report to Elsam Engineering A/S for the Harbour Porpoise Monitoring Program (2004)
This report was requested by Elsam Engineering A/S. It consists of a summary of results obtained in 2004 from the ongoing monitoring program of harbour porpoises in and around Horns…
The diel rhythms of biosonar behavior in the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) in the port of the Yangtze River: The correlation between prey availability and boat traffic
Wang, Zhitao; Akamatsu, Tomonari; Wang, Kexiong; Wang, Ding
PLoS ONE (2014)
Information on the habitat use of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is critical for its conservation. The diel biosonar behavior of the porpoise in the port…
Relative abundance of harbour porpoises (Phocoena phocoena) from acoustic and visual surveys of the Baltic Sea and adjacent waters during 2001 and 2002
Gillespie, D.; Berggren, P.; Brown, S.; Kuklik, I.; Lacey, C.; Lewis, T.; Matthews, J.; McLanaghan, R.; Moscrop, A.; Tregenza, N.
Journal of Cetacean Research and Management (2005)
Boat-based acoustic and visual surveys for harbour porpoises (Phocoena phocoena) were conducted during the summers of 2001 and 2002 in order to investigate their distribution and relative abundance in the…
Echolocation detections and digital video surveys provide reliable estimates of the relative density of harbour porpoises
Williamson, Laura D.; Brookes, Kate L.; Scott, Beth E.; Graham, Isla M.; Bradbury, Gareth; Hammond, Philip S.; Thompson, Paul M.
Methods in Ecology and Evolution (2016)
1. Robust estimates of the density or abundance of cetaceans are required to support a wide range of ecological studies and inform management decisions. Considerable effort has been put into…
A visual and acoustic survey for harbour porpoises off North-West Africa: Further evidence of a discrete population
Boisseau, O.; Matthews, J.; Gillespie, D.; Lacey, C.; Moscrop, A.; El Ouamari, N.
African Journal of Marine Science (2007)
The distribution of harbour porpoises Phocoena phocoena in southern Europe and along the Atlantic African coast is poorly understood, with tentative assessments suggesting a discrete West African population with a…
Harbour porpoise (Phocoena phocoena Linnaeus, 1758) entering the Weser river after decades of absence
Wenger, Denise; Koschinski, Sven
Marine Biology Research (2012)
Since 2005, harbour porpoise (Phocoena phocoena) sightings in the lower course of the river Weser have been reported after decades of apparent absence. The aim of this study was to…
Click train patterns of free-ranging harbour porpoises acquired using T-PODs may be useful as indicators of their behaviour
Koschinski, S.; Diederichs, A.; Amundin, M.
Journal of Cetacean Research and Management (2008)
Harbour porpoise signals consist of directional, high frequency stereotypic clicks which can be logged using T-PODs. Variation in interclick intervals (ICIs) can be used to distinguish different acoustic behaviours. So…
