Forskning på bar! Kom og hør om spennende havforskning på Statsraaden Bar

«På kryss og tvers av en av verdens sterkeste havstrømmer med Statsraad Lehmkuhl» – på Statsraaden Bar torsdag den 28.09.2023 kl. 19-20.


Under jordomseilingen «One Ocean Expedition» med Statsraad Lehmkuhl, hadde Nansensenteret ansvaret for etappen mellom Maputo (Mosambik) og Cape Town (Sør-Afrika). Vi hadde med oss seksti studenter som samlet inn og analyserte data fra satellitter og fra instrumenter om bord.

Vi kan si med stor sikkerhet si at vi bare har sett begynnelsen på klimakrisen. Fremtiden vil bli verre. Langt verre.

Surprising findings on the future of warming in the Arctic

The Arctic has been warming rapidly, and Richard Davy from the Nansen Center and Philipp Griewank from the University of Vienna set out to find out how this trend will change throughout this century. 

Our annual report for 2022 is out!

The Nansen Center focuses on advancing knowledge and forecasting changes in the marine environment and climate. If you are interested what our researchers have been working on throughout 2022, take a look at our latest annual report.

Visit by the Indian Minister of Earth Sciences

Extensive collaboration between Norwegian and Indian research institutions has been going on for decades. On Friday, the Indian Minister of Earth Sciences, Hon'ble Kiren Rijiju and Ambassador of India HE Dr. B. Bala Bhaskar visited the Nansen Center and Bjerknes Center and engaged in discussions on future bilateral collaboration on marine, polar and climate research.

Contributing to the Copernicus Marine Services

The Nansen Center leads the Arctic Marine Forecasting Center, which is part of the Marine Services of the European Union’s Earth Observation Programme Copernicus. We provide a range of products, which are freely available on the Copernicus Marine data portal.

Research school on supporting the development of sustainable smart cities

A research school tied to the URSA-MAJOR project will be happening in November. URSA-MAJOR stands for “Urban Sustainability in Action: Multi-disciplinary Approach through Jointly Organised Research Schools”. The project integrates research advances into a holistic educational programme for future stakeholders of Smart Cities. It focuses on the regions of amplified climate change where urban areas are in urgent need to improve their sustainability and resilience.

Monitoring sea ice from space and how to do it

A recent article led by Stein Sandven from the Nansen Center reviews the developments in sea-ice remote sensing over the last decades, benefitting operational ice services and polar climate science.

What’s behind multi-year ice decline in the Arctic?

Researchers at NERSC developed a method to track the evolution of multi-year ice more reliably in our sea-ice model neXtSIM. 

New insights in monitoring the Arctic from space

Two review articles were recently published, both focusing on satellite observation of the Arctic, what we have learned from it, what we still don’t know, and how we will better exploit data from new satellite sensors in the future. 

Forecasting of harmful algae blooms now more reliable

One of the biggest fears of shellfish farmers are tiny algae. Their abundance can now be predicted four weeks in advance.

Global temperatures predicted to reach new extremes in the next five years

Last week, this year’s WMO Global Annual to Decadal Climate Update by the World Meteorological Organization was released. The Nansen Center contributes to these updates by running climate predictions with NorCPM, the Norwegian Climate Prediction Model. This happens through the collaboration within the Bjerknes Climate Prediction Unit.

Your mission is to move a fractal, where do you start?

Yue Ying and his colleagues have proven that their new data assimilation method is able to reliably correct the position of vortices – swirls in water. They have high hopes for its use on features in sea ice like cracks and ridges, improving operational sea-ice forecasting.


Keeping an advanced sea-ice forecast on track with advanced data assimilation

A new study shows that including satellite-based data for sea ice concentration and thickness through data assimilation can make our sea-ice forecasts with neXtSIM more accurate.

One step closer to improved tools for studying the past and measuring the future Arctic Ocean

Researchers from the Nansen Center, Spain, and the UK show in a recent study that they can reduce salinity errors in forecasts and reanalyses of the Arctic Ocean by using salinity data measured from a satellite, and a data assimilation technique.


The One Ocean Expedition is coming to an end

Something extraordinary is happening in Bergen: The One Ocean Week.

A third of the new winter sea ice in the Arctic forms within cracks in the sea-ice cover

Do you know how sea ice grows during winter in the Arctic? This is what a recent study led by Guillaume Boutin at the Nansen Center investigates, focusing on how cracks in the sea-ice cover impact sea-ice growth, using our unique sea-ice model neXtSIM.


One Ocean Expedition – Vi er på vei!

Tirsdag 3. januar la seilskipet Statsraad Lehmkuhl ut på en av de siste etappene av One Ocean Expedition, og nå er Nansensenteret medseiler!

Seilasen går fra Maputo i Mosambik til Cape Town i Sør-Afrika.


I løpet av toktet holder vi kurs i oceanografi for studenter fra hele verden, i samarbeid med den europeiske romfartsorganisasjonen ESA. Info om kurset finner du her.

The Nansen Center and the Nansen Environmental Research Center – India (NERCI) co-organized a two-day international conference in India addressing the future energy systems in cities in southern Asia.

30 years anniversary of the Nansen Centre in St. Petersburg

The Nansen International Environmental and Remote Sensing Centre (NIERSC) in St. Petersburg was founded in 1992 and is celebrating its' 30th anniversary this October.
