Intelligent robots as a tool to understand climate changes in the Arctic Ocean

On September 12th 2018, R/V Kronprins Haakon left Longyearbyen on the second cruise in the research project named “the Nansen Legacy”. Its goal, to study oceanographic processes north of Svalbard, in order to understand the effects of changes in the water masses due to inflow of Atlantic water masses.

Atmospheric response to changes in sea ice concentration within the marginal ice zone

In a newly published Nansen Legacy study, scientists Yurii Batrak and Malte Müller from the Norwegian Meterological Institute show how the resolution of the spatial sea ice characteristics in model simulations significantly influences the 12‐hr weather forecast in areas up to 500–1,000 km away from the sea ice edge.

Dramatic shift to Atlantic climate in Arctic warming hotspot

The Arctic is about to shrink, shows a new study, as an important part of the Arctic Ocean shifts over to an Atlantic climate regime. The rapid climate shift occurs in the northern Barents Sea—the Arctic warming hotspot where the surface warming and loss of winter sea ice is largest in the entire Arctic.
