Marine Ecology Progress Series (2002)
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…
The effect of acoustic harassment devices on harbour porpoises (Phocoena phocoena) in the Bay of Fundy, Canada
Johnston, Dave W.
Biological Conservation (2002)
Many salmon aquaculture sites in the Bay of Fundy employ acoustic harassment devices (AHDs) to deter seals from approaching fish pens. These devices may also exclude harbour porpoises (Phocoena phocoena)…
Characteristics of echolocation signals used by a harbour porpoise (Phocoena phocoena) in a target detection experiment
Teilmann, Jonas; Miller, Lee A.; Kirketerp, Tim; Kastelein, Ronald A.; Madsen, Peter T.; Nielsen, Bjarke K.; Au, Whitlow W. L.
Aquatic Mammals (2002)
The characteristics of echolocation signals used by a harbour porpoise (Phocoena phocoena) during a target detection experiment are described. A water-filled steel sphere (either 5.08 or 7.62 cm in diameter)…
An automatic system for detecting and classifying the vocalisations of harbour porpoises
GILLESPIE, DOUGLAS; CHAPPELL, OLIVER
Bioacoustics (2002)
A system for automatically detecting the vocalisations of Harbour Porpoises Phocoena phocoena is described. The system consists of a high frequency hydrophone, an analogue electronics module and software running on…
Ontogenetic allometry and body composition of harbour porpoises (Phocoena phocoena, L.) from the western North Atlantic
McLellan, W. A.; Koopman, H. N.; Rommel, S. A.; Read, A. J.; Potter, C. W.; Nicolas, J. R.; Westgate, A. J.; Pabst, D. A.
J. Zoology (2002)
North Atlantic harbour porpoises Phocoena phocoena (L.) face considerable energetic challenges, as they are relatively small marine mammals with an intense reproductive schedule and a cold-water habitat. Post-natal growth of…
Harbour porpoise interactions with the 2001 selective salmon fisheries in southern British Columbia and license holder reported small cetacean by-catch
Hall, A.; Ellis, G.; Trites, A.W.
Selective Salmon Fisheries Science Program Report (2002)
We estimated the incidental mortality of harbour porpoise (Phocoena phocoena) in selective salmon fisheries in southern British Columbia from reports received from federal fisheries observers (2001) and license holders (1997…
Abundance of harbour porpoise and other cetaceans in the North Sea and adjacent waters
Hammond, P.S.; Berggren, P.; Benke, H.; Borchers, D.L.; Collet, A.; Heide-Jørgensen, M.P.; Heimlich, S.; Hiby, A.R.; Leopold, M.F.; Øien, N.
Journal of Applied Ecology (2002)
1. The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide…
Skin density and its influence on buoyancy in the manatee (Trichechus manatus latirostris), harbor porpoise (Phocoena phocoena), and bottlenose dolphin (Tursiops truncatus)
Kipps, E. K.; Mclellan, W. A.; Rommel, S. A.; Pabst, D. A.
Marine Mammal Sci (2002)
This study investigated how skin contributes to buoyancy control in the Florida manatee (Trichechus manatus latirostris), harbor porpoise (Phocoena phocoena), and bottlenose dolphin (Tursiops truncatus). Manatees are shallow divers and…

Effect of the sound generated by an acoustic harassment device on the relative abundance and distribution of harbor porpoises (Phocoena phocoena) in Retreat Passage, British Columbia
Olesiuk, Peter F.; Nichol, Linda M.; Sowden, Margaret J.; Ford, John K. B.
Marine Mammal Sci (2002)
We describe an experiment conducted to assess the impact of the sound generated by an acoustic harassment device (AHD) on the relative abundance and distribution of harbor porpoises (Phocoena phocoena)…
