The Arctic sea ice cover is a sensitive indicator of climate variability and change.

A new study from the Bjerknes Centre explains decadal variations in the oceanic circulation south of Greenland and Iceland. 

A large part of the changes in the warm water flow can be inferred from observations of sea surface height.

A recent study by Bjerknes Centre scientists demonstrates the link between observed fluctuations of atmospheric jet streams and the theoretical concepts that describe why jet streams exist.

The dominating exchange of carbon in the Nordic Seas takes place across the Greenland-Scotland Ridge. Horizontal transport of carbon in the region is almost two orders of magnitude larger than the uptake from the atmosphere in the Nordic Seas.

In a new study published in Ocean Science, Bjerknes Centre scientist Anders Sirevaag and co-authors present results from a 16 day long drift experiment in the central Arctic Ocean in 2008. Compared to the early 1990’s, the measurements from 2008 show that the upper central Arctic contained more freshwater in the summer, but was saltier during winter. This indicates that there has been a transition towards a more seasonal Arctic ice cover, which means that more ice is forming during winter and melting during summer.

A recently published study from the University of Bergen and the Bjerknes Centre indicates that an increase in the strength of the cold northerly winds may increase the transport of warm Atlantic water into the northern sea, and consequently a reduced Arctic sea ice cover.

Model study reveals that future large and episodic volcanic eruptions induce favourable climate condition for more land and oceanic carbon uptake and delay climate change effect.

A new article in Nature Geoscience revises our current understanding of how the dense overflow waters from the Nordic seas are formed.

The world oceans uptake of CO2 will decrease in our century under global warming, but there are big regional differences.
