Start of cruise with Research Vessel (R/V) Kronprins Haakon to look at winter processes in the northern Barents Sea and adjacent part of the Arctic Ocean.

When the first Fram-expedition returned to Norway in 1896, after three years frozen into the ice of the Arctic Ocean, a crew of 13 men was enthusiastically welcomed home and celebrated as heroes, above all the young Fridtjof Nansen. Hundred and twenty-five years after Fram, research vessels are exploring the Arctic Ocean on more regular basis, and onboard are men no longer among themselves. Women have become important contributors to the scientific exploration of the Arctic Ocean.

What do you think of when you think of the Arctic ocean? Belugas weaving through ice floes? Or maybe walruses sunbathing on a chilly beach? How about a polar bear hunting for its next seal snack?

Interview with Louise Steffensen Schmidt (The Nansen Legacy), Postdoc at the Department of Geosciences, University of Oslo. Recently, she presented her research work in the lecture: Variability in glacier meltwater runoff to the Barents Sea, at the 3rd Nansen Legacy annual meeting, 10-12 November 2020.

The jet stream is a highway for cyclones, while the sea ice edge has been thought to be a fuel station. Erica Madonnas new study shows that the fuel for cyclones is not simply linked to the location of the ice edge. She explains Barents Sea cyclones as a traffic system.

In science, it is difficult to understand the whole picture when you only have fractions. As a puzzle, the Barents Sea is lacking some of the pieces to be a complete picture that you can hang on the wall.

Scientists in movies and on television are often presented as brilliant people, knowing exactly what they do and what they want to achieve, furthermore, their experiments always succeed. That is, if they fail, they fail spectacularly, becoming mutants, blowing up the world or some such. This post is about real scientists and failing unspectacularly.

Understanding who eats who is important to describe how nutrition and energy move between species in marine ecosystems. The field of research is flourishing like never before thanks to new technology and more advanced methods. These allow us to uncover hitherto unknown connections that occasionally shake up known paradigms in ecology.

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.

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?

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.

We are proud to share a glimpse of our many project activities from 2019. The report highlights of the new scientific knowledge that has started to emerge. It presents some of our research activities, our scientists and recruits.

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.

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 ecosystem

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.

Vladimir Savinov, a researcher at Akvaplan-niva (APN), is among the scientific crew on the R/V Dalnie Zelentsy, a 55 m Russian ship conducting monitoring surveys in the eastern Barents Sea.

By taking into consideration the insulating effect of snow on top of sea ice, researchers improve our weather forecasting capabilities in the Arctic.

The Arctic’s once impenetrable ice cap is melting away, with profound consequences for everything from ocean circulation patterns to fish numbers and diversity. The Nansen Legacy Project, including NTNU biologists,

In July 1873 some nets were put out by whalers in Raudfjorden in Svalbard, to obtain food. They had expected to catch Arctic char but ended up filling the nets with cod.

Norway has always been a polar nation. The search for Arctic marine natural resources gave Norwegians early experience and knowledge of Arctic waters, which were later strengthened and systematically described

While you are still enjoying the warm summer and a rich selection of fruits and berries, a large-scale preparation for winter is happening further North. In the Northern Barents Sea

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.

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.

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.

Central to the fieldwork of the project is the research vessel Kronprins Haakon. It has been built to operate in challenging ice conditions, which means it can go further north and south than

Two interesting PhD positions available in the Human Impact: Pollution task of the Nansen Legacy project, one at UiO and one at UNIS.

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.
