Improving the monitoring and forecasting of sea ice, icebergs, and biodiversity in the ocean

The Nansen Center is a partner in two new projects funded by the European Commission's Horizon Europe programme. The projects will enhance existing and develop new products in Copernicus, the European Union's Earth Observation programme.  


Strong Nansen Center presence at the ESA Living Planet Symposium

The European Space Agency (ESA) arranges the Living Planet Symposium (LPS) every third year. It is the biggest Earth observation conference in the world, and it offers fantastic options to present research findings to scientists and data users and discuss the importance of Earth observations in the future. This year’s topic of LPS was “Taking the pulse of our planet from space”, an objective that overlaps with the Nansen Center’s strategy, as remote sensing is one of the legs we stand on.   

International collaboration in the Arctic with the Office of Naval Research, the Norwegian Coast Guard, and Scripps Institution of Oceanography

Last week, the Nansen Center had several prominent guests from the United States, the United Kingdom, and Norway. The reason for the visit was to discuss collaboration efforts and show highlights from the past two decades of collaboration in research, training, and technology between Norway and the USA.

Seven decades of environmental change at deep-sea sponge grounds

A recent study led by Annette Samuelsen investigated environmental change at deep-sea sponge grounds in the North Atlantic. She and her team were able to establish a baseline for water conditions in four different areas through simulations – over 67 years. Such a baseline is important for future studies. Sponges have far-reaching implications for life both in the ocean and on land, and their wellbeing is dependent on their environment.


The Nansen Center is now a member of the University of the Arctic

On Wednesday the 1st of June, the members of the Assembly of the University of the Arctic unanimously voted in favour of accepting the Nansen Center into the network.

What is the University of the Arctic?

A tiny wooden boat made its way from the Arctic Ocean to the coast of Northern Norway

As part of the Float Your Boat outreach project, hundreds of school children in the US and Norway decorated their own boats in 2020 and 2021. These were set out on top of the floating sea ice in the Arctic, and now the first boat from two years ago has finally made its way back to Norway – to Arnøya at the northernmost part of Norway’s coast.

Measuring the sea level along the Norwegian coast from space

PhD candidate Fabio Mangini (UiB/NERSC) recently published his second article, and his findings confirm that satellites can be used to reliably determine regional variations in the sea level in coastal zones of Norway. This is relevant for predicting future changes along coastlines, helping society to mitigate effects of climate change.


Why is the sea level important?

Cleaning up satellite images to make marine activities in the Arctic safer

People have been using the Arctic Ocean for over a century, mainly for shipping goods between the Atlantic and the Pacific Oceans. The northern passages come with dangers though – sea ice poses a significant threat to shipping and other marine activities. In the past decades, technological advances have made it safer to cross these waters, but the ocean and sea-ice conditions in the Arctic remain challenging. A recent study led by Anton Korosov at the Nansen Center is contributing to increase safe navigation in the Arctic.

Making climate models more accurate by improving their tuning

Earth’s climate is a very complex system, and it is not easy to understand with all its components – the main ones being ocean, land, atmosphere, and sea ice. Nevertheless, scientists have been trying for decades to predict future changes in climate with numerical models. These models keep getting better, but all components have systematic errors to some degree. Decreasing errors and thereby predicting the future climate more reliably will benefit society by allowing us to better adapt to climate change.

Commemoration of the 15th Anniversary of Atmospheric and Oceanic Science Letters

The establishment of the Nansen-Zhu International Research Center (NZC) in 2003 at the Institute of Atmospheric Physis, Chinese Academy of Sciences in Beijing has significantly contributed to climate research over almost two decades.

Predicting when and where unusually warm water is travelling from the Gulf Stream to the Arctic

About every 14 years, a significant temperature change is observed in the ocean between Greenland and Svalbard. Why, you wonder? Well, the Gulf Stream transports warm water northwards and on a regular basis, the water is even warmer and saltier than normally. These variations are regular, but can we predict these changes reliably? 

The Nobel Peace prize laureate Archbishop Desmond Tutu died at age of 90.

We have received the sad news that Archbishop Desmond Tutu, the Nobel Peace prize laureate has died at age of 90 (front photo - courtecy Taarifa, October 13 - 2020). A man of extraordinary intellect, integrity and invincibility has passed away.

Can we predict what our climate might be like in the near future?

We can predict the weather about 10 days ahead of time, and climate projections look at how the climate will look like a hundred years from now. In between, we find a new field of science: climate prediction. A new publication describes how good our Norwegian Climate Prediction Model is at predicting the climate for our near future.

The Nansen Center - a brief look back at 35 forward-looking years

Inspired by Fridtjof Nansen's lifelong forward-looking efforts for research, exploration, diplomacy, and humanitarian work, the Nansen Environmental and Remote Sensing Center was established on the 28th of November 1986. The Center aimed to use new measurements from ships, aircraft, satellites, and computer models to obtain new knowledge about the ocean and sea ice. Today, 35 years later, this is still extremely relevant. The few tools that were available back then were new and under constant testing and development.

Why a 1 square km datapoint is better than a 900 square km one

Changes in climate have wide-reaching implications for life on Earth. By looking at the past climate we can understand ongoing processes better. But global datasets covering the past climate have too low resolutions to be useful for small-scale investigations like crop yield modelling – until now!


Nansensenteret – et kort tilbakeblikk på 35 framoverskuende år

Inspirert av Fridtjof Nansens framoverskuende innsats for forskning, utforskning, diplomati og humanitært arbeid, ble Nansen senter for miljø og fjernmåling etablert den 28. november 1986. Senteret ville bruke nye målinger fra skip, fly og satellitter og modeller for å etablere ny kunnskap om havet og sjøisen. I dag, 35 år senere, er dette fortsatt høyst relevant. Verktøyene som den gang var få, nye og under stadig utprøving og utvikling, er nå i daglig bruk og med langt mer nøyaktighet og regnekraft enn det som var mulig i 1986.

Nansen Scientific Society 15 years

The Nansen Scientific Society (NANSI) was founded as an ideal independent foundation under the slogan “Knowledge without borders”. During these 15 years 52 students have been supported with educational or mobility grants, 11 research schools have been co-funded and the overall activities have resulted in 60 scientific publications. The Nansen Center congratulates NANSI with its great achievements for the first 15 years.


The IPCC climate reports' cousin: The CMEMS Ocean State Report!

The IPCC reports are well known and focus on the Earth's climate with all its facets, but have you heard about the ocean equivalent? Changes in the ocean have wide-reaching implications for the climate and life on Earth, so monitoring these changes and being able to make predictions of future changes is crucial.
