Recent “Atlantification” of the Arctic is characterized by warmer ocean temperatures and a reduced sea ice cover. The Barents Sea is a “hot spot” for these changes, something which has broad socioeconomic and environmental impacts in the region. However, there is, at present, no complete understanding of what is causing the ocean warming.Read More
Warm Atlantic water (AW) that flows northward along the Svalbard west coast is thought to
transport enough heat to melt regional Arctic sea ice effectively. Despite this common assumption, quantitative requirements necessary for AW to directly melt sea ice fast enough under realistic winter conditions are still poorly constrained.
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?Read More
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.Read More
I am privileged. I have worked in some of the most remote places on this planet, and I have seen forms of life that only few know of, some of which have not yet gotten a name.Read More
Numerical models help us to make sense of complicated data or to test our hypotheses. For this reason, they are increasingly used in studies and analyses supporting fisheries and ecosystemRead More
SIDE EVENTS ARCTIC FRONTIERS Organized by The Nansen Legacy How can knowledge from a science project reach users and policy makers? And how can we increase the competence among scientistsRead More
In times of climate change and retreating sea ice, important research questions are for example: How important are sea ice algae as a food source for organisms such as copepods, krill and fish? Are they affected by the sea ice retreat and if so, how will that affect the functioning of the Arctic ecosystem?Read More
As the polar night lowers over the Arctic, RV Kronprins Haakon is leaving the quay in Longyearbyen, heading towards the Arctic Ocean. For the next two weeks, the researchers and technicians on board will retrieve old and deploy new scientific measuring equipment in the sea area around Svalbard.Read More
The sea ice extent in the Barents Sea was back to normal this winter. A paradox? Actually not. This text was published in Aftenposten (online and print) 23 April 2019.Read More
September onboard the research vessel Lance north of Svalbard. Kristen, our mooring engineer, is happy. There is no sea ice to be seen anywhere – ideal conditions to find the instruments we left here two years ago attached to a rope, anchored to the seafloor, and held upright under water by several buoys.Read More
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.Read More
Changes in the marine environment are causing shifts in ecosystems north of Svalbard.Read More
The UK-based project Changes of the Arctic Ocean Seafloor (ChAOS) joined the last Nansen Legacy research cruise with two scientists from the University of Leeds, UK. Mark Zindorf and Allyson Tessin describe their work and motivation to join the Nansen Legacy cruise.Read More
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.Read More
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.Read More
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.Read More
Hundred and twentyfive years after “Fram” left for its historic Arctic expedition, the new Norwegian research icebreaker “Kronprins Haakon” left Tromsø on August 6, for its first scientific expedition to the Barents Sea. Onboard are 32 Nansen Legacy scientists.Read More
“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.Read More
Studying the Arctic spring requires a suit of different approaches and methods, as Nansen Legacy’s collaborating project Arctic PRIZE is showing in this video.Read More
Nansen Legacy scientists were strongly represented at the 18th Russian-Norwegian Symposium in Murmansk 5-7 June 2018. The topic of the symposium was highly relevant for the Nansen Legacy project, by addressing the influence of ecosystem changes on harvestable resources in high latitudes.Read More
In a new British documentary, Nansen Legacy scientists Katrine Husum and Geir Wing Gabrielsen from the Norwegian Polar Institute are sharing their impressions of the vast changes in the Arctic ecosystem with Lewis Pugh, who swam one kilometer in sub-zero Arctic waters to draw the World’s attention to the fast loss of Arctic sea ice and ice-connected life.Read More
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.Read More
Who will win the battle of the Atlantification and ecological balance of the Arctic? The army from the North or the army from the south?
A new short film has been released by VOX, featuring both scientists Jørgen Berge and Ireen Vieweg, from the Nansen Legacy and research touching the topics of the project.Read More
Emmelie K. L. Aström defended her PhD last Friday 20th April. The day before, she learned that she has been awarded a prestigious VISTA (The Norwegian Academy of Science and Letters) Post-Doctoral position connected to the Nansen Legacy.
Meet her here.Read More
The “Siberian cold” that has been entering Europe for the past weeks is in strong contrast to what is experienced in the rest of the Arctic! This winter is the warmest ever recorded.Read More
