Horizon2020 INTAROS movie - Field experiment in the Arctic Ocean

Publication on Tourism in the Marginal Ice Zone

Students participating in the interdisciplinary summer research school The Arctic Ocean and the marginal ice zone (MIZ) - interdisciplinary research, management practices, and policy developments in 2017 have now published their results in Polar Geography.

Global warming transforms the Arctic cloud cover

The Arctic is one of the cloudiest regions on the Earth. White carpet of clouds typically covers the Arctic during three quarters of year. In summertime, clouds reflect sunlight helping to keep the Arctic cool. In winter time, they capture and backscatter heat making the Arctic warmer than it could be under a clear sky.

Strengthening polar research cooperation with The Republic of Korea

The Korean Polar Research Institute (KOPRI) and the Nansen Center have made an amendment to their memorandum of understanding strengthening the bilateral research and educational cooperation in the Arctic Ocean.

Annual report 2018 has been released

The Nansen Center has released its´ annual report for 2018. 

This year we decided to do it differently compared to previous years – to make the report more “tasty” by giving it a new design and format. For the first time the report is now available as an interactive online book. By doing so, it is my hope that the annual report will be more readable and easily accessible for the public. A format we will stick to in the future.


- Forskning er like gøy som jeg trodde

Olav Ramslien fra Knarvik Ungdomsskule hadde før påske arbeidsuke hos Nansensenteret og UiB (BIO/GEO). Olav er veldig glad i realfag og hadde i arbeidsuken lyst til å få et innblikk i hva forskning kan innebære. - Det har vært ekstremt kjekt å jobbe på Nansensenteret, og jeg har fått mange utfordringer å bryne meg på, sier Olav Ramslien etter å ha erfart arbeidsplasser i forskningsmiljøet i Bergen. 

Prime Minister Solberg visited the Nansen Center in Russia

This week The International Arctic Forum takes place in St. Petersburg, Russia. All the Nordic state leaders are participating alongside president Vladimir Putin. The Nansen Center in St. Petersburg (NIERSC) had the pleasure of hosting Prime Minister Erna Solberg together with the Norwegian press at the Russian icebreaker Krasin.

Key indicators of Arctic climate change: 1971–2017

Key observational indicators of climate change in the Arctic, most spanning a 47 year period (1971–2017) demonstrate fundamental changes among nine key elements of the Arctic system. A new study finds that, coherent with increasing air temperature, there is an intensification of the hydrological cycle, evident from increases in humidity, precipitation, river discharge, glacier equilibrium line altitude and land ice wastage. Director at the Nansen Center, Sebastian H.

Towards an advanced observation system for the marine Arctic

The Arctic marine climate system is changing rapidly, which is seen in the warming of the ocean and atmosphere, decline of sea ice cover, increase in river discharge, acidification of the ocean, and changes in marine ecosystems. Socio-economic activities in the coastal and marine Arctic are simultaneously changing. PEEX ("Pan-Eurasian Experiment”) is a research infrastructure program focused on climate and environmental changes in the Northern Eurasian arctic and boreal regions.

Marin temaaften ved Nansensenteret

Over 100 deltakere fra forskningsmiljøene, marin og maritim næring samt klyngeorganisasjoner i Bergen møtte til Marin temaaften ved Nansensenteret.

In memory of legendary Walter Munk

Walter Munk passed away 8th of February at the age of 101. The Legendary Scripps oceanographer defined a field of science, transformed understanding of nature, helped nurture a university into existence, and became a living synonym for oceanography.

Paper: Spatial structure and temporal variability of a surface urban heat island in cold continental climate

Authors: Victoria Miles and Igor Esau at the Nansen CenterAuthors: Victoria Miles and Igor Esau at the Nansen CenterWarm urban climate anomalies are a challenging problem for city’s economy and ecology. This problem is even more pressing in boreal environment with its sensitive ecosystems and considerable anthropogenic urban heat flux. The boreal regions of Eurasia witness both rapid urbanization and accelerated regional warming in the twenty-first century. Still, local climate of boreal cities is only fragmentary studied.

The climatology of the atmospheric boundary layer

Richard Davy: Researcher at the Nansen CenterRichard Davy: Researcher at the Nansen CenterThe new paper from Richard Davy “The climatology of the atmospheric boundary layer in contemporary global climate models” out now in Journal of Climate is the first to quantify the climatology of the atmospheric boundary layer in the full ensemble of climate models in CMIP5 – the climate model inter-comparison project which is widely used for the IPCC reports.


Debatt under Arctic Frontiers: Det grønne skiftet - hva nå?

Arctic Frontiers arrangeres i Tromsø denne uken. På åpningsdagen ble det invitert til debatt om "Det grønne skiftet - hva nå?". I panelet møtte Nansensenterets direktør Sebastian H. Mernild blant annet klimaministeren til debatt.

Her kan du se debatten i opptak (på grunn av tekniske lydutfordringer hos arrangør, er det først lyd fra da debatten startet. Spol derfor frem til 5:25)


Snow and ice changes in the Andes mountains during the last 70 years


The loss rate of Arctic land ice has increased threefold

New GEUS-led study shows the loss rate of Arctic land ice has increased threefold since 1986, from nearly 5000 tons of water per second during the “recent past” (1986–2005) to 14,000 tons per second in the present day (2005–2015).

"This is a solid scientific study that gives a temporal description of how the land ice in the Arctic contributes to the rising sea-level. The numbers are worrying as the loss of land ice from the Arctic has risen to three doubles in the period 1986-2005 to 2005-2015", says one of the authors Sebastian H. Mernild.

Film fra 1993 med fokus på fremtidens klimasituasjon

"Med bud om morgendagens klima" ble filmet under et av toktene i 1992 og produsert ferdig i 1993. I dag er det interessant å se hvilke perspektiver man hadde på klima for 25 år siden. En problemstilling som bare har blitt enda mer aktuell. Filmen er produsert og regissert av Carlo for Nansensenteret.

New podcast episodes

The Bjerknes Center and its partners; the University of Bergen, the Nansen Center, NORCE and the Institute of Marine Research, are collaborating on a new podcast that started earlier this fall. A total of seven episodes have been recorded so far at UiB in Media City Bergen. Currently, the podcasts have been in Norwegian, but soon English-language episodes will be produced. In these, Stephen Outten from the Nansen Center will be a moderator.
