The elusive sea ice edge

Last winter an almost forgotten sight presented itself to all those venturing the Barents Sea: sea ice as far south as Bjørnøya, equaling a sea-ice extent not seen since the eighties and nineties. Are you wondering how this is possible in times of global warming and a diminishing Arctic ice cap?

Polar cod have become larger in the Barents Sea over the last 30 years

Polar cod is a key fish species, transferring energy from zooplankton to larger animals. Polar cod depend on sea ice for spawning and during the early parts of its life. Reduced ice cover may therefore influence the survival and growth of young polar cod directly through e.g. loss of predation refuge, and indirectly by e.g. affecting the abundance and availability of prey.

The Ever Moving Sea Ice

The Arctic sea ice is on the move all year. It expands to its maximum during March and reaches its minimum in September. The variation during the year, and from year to year, depends on wind, weather and ocean currents. But the Arctic is changing.

The Nansen Legacy

Fridtjof Nansen set out to explore the Arctic Ocean with the research vessel Fram 126 years ago. His team of explorers and scientists returned from the ice three years later with new knowledge that changed our concepts and understanding of the Arctic Ocean, and made the Arctic part of Norwegian identity.

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.

Testing Norways new icebreaker

“There are many bits and pieces that need to fall in place with a new vessel like “Kronprins Haakon”, as well as a large research project like the Nansen Legacy, but both the vessel as well as the project are run by many incredibly competent and hard-working persons”, says Nansen Legacy PI Marit Reigstad.

TV Documentary: True North

What is a oceanographic mooring? How do these supplement to the time series in the Arctic? How can these help us understand the changes happening when North Atlantic water that flows into the Arctic is warming, melting the sea ice and changing the delicate arctic ecosystems, currents and water masses?

Follow Nansen Legacy researcher, Arild Sundfjord and other members recover A-TWAIN moorings, adding to future time series and knowledge.
