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 large…
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 a…
The importance of tidewater glaciers for marine mammals and seabirds in Svalbard, Norway
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 are…

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.

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.

Results show that PBDEs have reached the Arctic, with polar cod, ringed seal, polar bear, and beluga whale showing higher PBDE levels and a more complex PBDE pattern than ringed seals, and polar bears contained only PBDE 47 in relatively small amounts.
State of the Climate in 2016
In 2016, the dominant greenhouse gases released into Earth's atmosphere-carbon dioxide, methane, and nitrous oxide-continued to increase and reach new record highs. The 3.5 +/- 0.1 ppm rise in glob…
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.
Eddy overturning of the Antarctic Slope Front controls glacial melting in the Eastern Weddell Sea
 The Eastern Weddell Sea is characterized by narrow continental shelves and Warm Deep Water (WDW) is located in close proximity to the ice shelves in this region. The exchange of WDW across the…
