Specimens of harbour porpoises, Phocoena phocoena, from both strandings and bycatch in fisheries around the United Kingdom between 1985 and 1994 have been examined. Full autopsies were undertaken on most…
Published and new fresh and museum specimens of Burmeister's porpoise, Phocoena spinipinnis, collected prior to the recent research in Peru, Chile and Argentina, are listed and described. Distribution is from…
Previous double team experiments testing line transect methodology for harbor porpoise indicated that a relatively small proportion of the sightings were actually seen by both teams. Results of an additional…
The seasonal distribution of harbour porpoises in US Atlantic waters is explored by examining aerial sightings made by the CeTAP survey between 1978 and 1988. Sightings rates were very low…
Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
We examined geographic variation in external measurements of Dall’s porpoises, using 269 sexually mature specimens from throughout their range, excluding coastal waters off North America and the northern Okhotsk Sea.…
The site and physiologic mechanism(s) responsible for the generation of odontocete biosonar signals have eluded investigators for decades. To address these issues we subjected postmortem toothed whale heads to interrogation…
The reported decline of the harbour porpoise in the coastal areas of the North Sea after 1940, has also been seen in Dutch waters. Information on the distribution and abundance…
This paper reviews and summarises published and unpublished information on harbour porpoises in Irish waters and presents results of recent research. Harbour porpoises have been recorded from all Irish coasts…
Harbour porpoises (Phocoena phocoena) are notoriously difficult to observe and become very difficult to see in moderate or rough sea conditions. Passive acoustic monitoring provides a complementary study method to…
