En ny studie publisert i det vitenskapelige tidsskriftet Nature viser at innlandsisen på Grønland smelter syv ganger raskere i dag enn på 1990-tallet.

Future extremes in surface wind and temperature in southwestern Norway

The article Estimates of changes in surface wind and temperature extremes in southwestern Norway using dynamical downscaling method under future climate recently published in Weather and Climate Extremes discusses future projections for extreme wind and temperature events. In this study, former Nansen Center scientist Dr.

Nansen Tutu Centre 10th anniversary symposium, Cape Town, South Africa: Ocean, weather and climate: Science at the service of society

In recognition of the 10th anniversary of the Nansen Tutu Centre for Marine Environment Research, we are organizing a symposium at the Breakwater lodge, situated at the waterfront in Cape Town, South Africa from 10 to 12 of March 2020. It will run in parallel with the Ocean Observation Panel for Climate meeting. The overall symposium theme is Ocean, weather and climate: Science at the service of society.

Can we use semi-qualitative observations to forecast the Arctic sea ice?

Dr Abhishek S. Shah.Dr Abhishek S. Shah.The answer was given during Dr. Abishek Shah´s the doctoral dissertation on 16. September at the Mathematical Institute, University of Bergen. His thesis dealt with the methods of data assimilation that blend observations and a numerical model into a forecasting system as used routinely by for example weather forecasts.

Data Assimilation summer school in Romania

Climate change leads to an increasing need for process understanding, reduced uncertainties, and more reliable data for mitigation and impact studies. This calls for a new generation of researchers that have strong and broad knowledge about the climate system in the fully coupled Earth System. The Norwegian Research School on Changing Climates in the coupled Earth System (CHESS) is a direct response to this demand.

Nansen research school on the climate of the Arctic in St. Petersburg

The international interdisciplinary PhD and Post-Doc research school on Observing and Modelling the Arctic – Climate processes, prediction and projection started today at the Nansen International Environmental and Remote Sensing Center (NIERSC) in St Petersburg.  

Making the 6th IPCC climate assessment report

The UN International Panel on Climate Change (IPCC) assesses the science basis for the ongoing climate changes. In 2017 the IPCC and UN defined the structure of the next climate assessment report (AR6) due to be launched in June 2022. The final report will comprise of three working group contributions on the science basis and a Synthesis report for policy makers to be launched in 2021.

Norwegian research expedition onboard KV Svalbard reached the North Pole

The international Coordinated Arctic Acoustic Thermometry Experiment (CAATEX) on board the Norwegian coast guard icebreaker KV Svalbard reached early today the North Pole. KV Svalbard reached the North Pole 125 years after Fridtjof Nansen tried to drift across the North Pole with his sailing vessel Fram.

Lyd skal ta temperaturen på hele Polhavet

Forskere skal for første gang på 20 år igjen benytte lydsignaler til å kartlegge havtemperaturen på tvers av hele Polhavet. Kystvaktskipet KV Svalbard legger i dag ut på tokt fra Longyearbyen med 18 forskere fra ni institusjoner.

Review paper: Arctic Region Component of the Global Ocean Observing System

An international research community review article has assessed the basis and made commendations for the development and implementation of an Arctic Region Component of the Global Ocean Observing System (ARCGOOS). Scientists from 24 research institutions in seven countries involved in polar research have contributed to this roadmap for an ocean observing system in the Arctic.

Aldri observert mindre sjøis i Arktis i begynnelsen av august

Siden midten av juli i år har det aldri tidligere vært observert mindre total utbredelse av sjøis i Arktis. Fortsatt er det cirka en og en halv måned igjen av smeltesesongen og årets absolutte minimum utbredelse av sjøis i Arktis som inntreffer i midten av september. Den tidligere årsminimumsrekorden inntraff i september i 2012 med en sjøisutbredelse på ca. 4,49 millioner kvadratkilometer.

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.
