Cetacean abundance and distribution in European Atlantic shelf waters to inform conservation and management
TLDR
The entire EU Atlantic continental shelf was surveyed in July 2005 to generate robust estimates of abundance for harbour porpoise and other cetacean species, and abundance in 2005 was similar to that in 2004. Expand
Pile driving zone of responsiveness extends beyond 20 km for harbor porpoises (Phocoena phocoena (L.)).
TLDR
Steel monopile foundations for offshore wind turbines were driven into hard sand in shallow water at Horns Reef, the North Sea, and impulsive sounds generated had high sound pressures and a strong low frequency emphasis but with significant energy up to 100 kHz. Expand
Impacts of offshore wind farm construction on harbour porpoises: acoustic monitoring of echolocation activity using porpoise detectors (T-PODs)
TLDR
Assuming that echolocation activity is related to harbour porpoise density, the analysis shows that their habitat-use changed substantially, with the porpoises leaving the construction area of the offshore wind farm. Expand
The 1988 and 2002 phocine distemper virus epidemics in European harbour seals.
TLDR
New and revised data for the phocine distemper virus (PDV) epidemics that resulted in the deaths of more than 23 000 harbour seals Phoca vitulina in 1988 and 30,000 in 2002 are presented and it is suggested that grey seal populations could act as reservoirs for PDV if infection rates in sympatric species are lower than in harbour seals.

All at sea with animal tracks; methodological and analytical solutions for the resolution of movement
TLDR
This paper considers the advances that deadreckoning can bring to the study of the often cryptic movement and behaviour of marine animals at sea and suggests how movement data derived from these devices can be analysed using indices that allow interpretation over a large variety of temporal and spatial scales.

Behaviour of ringed seals tagged with satellite transmitters in the North Water polynya during fast-ice formation
TLDR
Monitoring of eight ringed seals caught in the fjords of the Thule (Avernarsuaq) area in Northwest Greenland monitored the movements and diving behaviour of animals, finding the "shallow-water" seals dove significantly more frequently to depths of less than 50 m than the "deep-water", whereas the deep-water seals made significantly more dives. Expand
Integrating genetic data and population viability analyses for the identification of harbour seal (Phoca vitulina) populations and management units
TLDR
The study suggests that population genetic inference can offer the same degree of temporal and spatial resolution as ‘nongenetic’ methods and that the combined use of genetic data and PVAs constitutes a promising approach for delineating populations and management units. Expand
Ultra-High Foraging Rates of Harbor Porpoises Make Them Vulnerable to Anthropogenic Disturbance
TLDR
It is reported that porpoises forage nearly continuously day and night, attempting to capture up to 550 small fish prey per hour with a remarkable prey capture success rate of >90%, which means that they must forage almost continually to meet their metabolic demands with such small prey, leaving little margin for compensation.
