The marine ecosystem of Kongsfjorden, Svalbard
Kongsfjorden is a glacial fjord in the Arctic (Svalbard) that is influenced by both Atlantic and Arctic water masses and harbours a mixture of boreal and Arctic flora and fauna. Inputs from largeExpand
A simple new algorithm to filter marine mammal Argos locations
During recent decades satellite telemetry using the Argos system has been used extensively to track many species of marine mammals. However, the aquatic behavior of most of these species results in aExpand
Biomagnification of polybrominated diphenyl ether and hexabromocyclododecane flame retardants in the polar bear food chain in Svalbard, Norway.
This study demonstrates that PBDEs and HBCD have reached measurable concentrations even in the lower trophic levels (invertebrates and fish) in the Arctic and biomagnifies in the polar bear food chain. Expand
Impacts of changing sea-ice conditions on Arctic marine mammals
Arctic sea ice has changed dramatically, especially during the last decade and continued declines in extent and thickness are expected for the decades to come. Some ice-associated marine mammals areExpand
Arctic marine mammal population status, sea ice habitat loss, and conservation recommendations for the 21st century
Recommendations for effective AMM conservation are maintained and improved by local, federal, and international partners; recognize spatial and temporal variability in AMM subpopulation response to climate change; implement monitoring programs with clear goals; mitigate cumulative impacts of increased human activity; and recognize the limits of current protected species legislation.

The importance of tidewater glaciers for marine mammals and seabirds in Svalbard, Norway
Abstract Approximately 60% of Svalbard's land areas are glaciated at the present time. The Archipelago has more than 1100 glaciers (> 1 km2) and 163 of these are “tidewater glaciers” — that isExpand
Stratification, Composition, and Function of Marine Mammal Blubber: The Ecology of Fatty Acids in Marine Mammals
The remarkable dynamics of the middle layer along with the discrete pattern of stratification found in the vertical fatty acid profiles have important implications for methodological sampling design for studies of foraging ecology and toxicology based on analyses of blubber of marine mammals.

Feeding kinematics, suction and hydraulic jetting capabilities in bearded seals (Erignathus barbatus)
Feeding kinematics, suction and hydraulic jetting capabilities of bearded seals support predictions that mouth size, fluid flow speed, and elusiveness of prey consumed are among a suite of traits that determine the specific nature of suction feeding among species. Expand
Summer vocalisations of adult male white whales (Delphinapterus leucas) in Svalbard, Norway
It was found that Svalbard's white whales produced most of the vocalisations that have been documented in other populations, but they also displayed minor vocal novelties and differences. Expand
Serosurvey for Toxoplasma gondii in arctic foxes and possible sources of infection in the high Arctic of Svalbard.
The results suggest that migratory birds, such as the barnacle goose, may be the most important vectors bringing the parasite to Svalbard, and the age-seroprevalence profile in the fox population suggests that their infection levels are enhanced by vertical transmission. Expand
