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.

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!

 

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.

Smart Ocean 2021 survey cruise with KV Tor

11 students and researchers from NERSC and the University of Bergen participated in a 3-day cruise to Bjørnafjorden south of Bergen and the surrounding area, with the Norwegian Coast Guard vessel KV Tor. The cruise was a part of the SFI Smart Ocean project preparing for a mesoscale observing system using acoustic technology.

 

A summary of improvements to CMEMS' Arctic Monitoring Forecasting Center

Outputs by the Arctic Monitoring Forecasting Center are being used for Norwegian emergency response tools, among many other societally relevant applications. Laurent Bertino (DA research leader) and colleagues from MET Norway and the Institute of Marine Research summarized the changes and improvements made to the forecasting center’s products since it was established in 2015.

21 years of algae blooms observed from space

Edson Silva just published his first article as part of his institutional PhD project - congratulations! Together with five other co-authors from NERSC and one from the University of Bergen (UiB), he studied the annual cycle of phytoplankton/algae blooms in the Nordic Seas by utilizing satellite data from 2000-2020.

What is phytoplankton?

Wind of (climate) change: More frequent extreme winds over Europe in our future

Stephen Outten and a colleague from NORCE recently published a study on extreme winds over Europe for the remainder of this century, affecting more business sectors than you would think.

Marine sediments can tell us about climate change in eastern Africa 2 million years ago

A new publication in Nature shows that a shift in air circulation is responsible for the eastern African climate having changed to dry conditions about two million years ago. The authors studied a marine core to prove their hypothesis. Björn Backeberg is a co-author – he has an adjunct position with NERSC and is affiliated with Deltares in the Netherlands and the Nansen-Tutu Centre for Marine Environmental Research in South Africa.

Monsoon rainfall in India – How well do reanalyses compare to real-world data?

NERSC researcher Tarkeshwar Singh (CDP group) recently published an article with colleagues from India. They investigated the performance of three high-resolution atmospheric reanalyses over the Indian region by comparing the rainfall data with focus on the extreme events.

Automatically detecting fast ice and stamukhi from space

Denis Demchev (OSIRS group) and Valeria Selyuzhenok (Zubrov State Oceanographic Institute, Russia) recently published a study introducing a fully-automated method to track fast ice and stamukhi in Arctic coastal zones. Their method is faster and more objective than manually-produced operational sea-ice charts and can provide near-real time information!

New role for Einar Ólason: Co-leader of Arctic ECRA

Einar Ólason takes over the co-lead of the collaborative programme "Arctic", one of four core activities of the European Climate Research Alliance (ECRA). He supersedes Lars Henrik Smedsrud (GFI/UiB, UNIS, Bjerknes Centre), who held that position since 2014.

Researchers and students working together to collect observations of the ocean and Arctic sea ice

In June, our Acoustic and Oceanography Group organized a research cruise onboard the Norwegian Coast Guard Vessel KV Svalbard. Students and experienced scientists worked side by side to collect sea-ice and oceanographic data. Engagement and involvement are essential to train the new generation of scientists in conducting Arctic field work. 

 

Nansensenteret gratulerer Nobelprisvinner og venn Klaus Hasselmann

Nobelprisen i fysikk 2021 ble tildelt Klaus Hasselmann og Syukuro Manabe for deres bidrag til “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming” og Giorgio Parisi for “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales” (referanse: nobelprize.org)

Nansen Center new Network Partner in the Norwegian-British Chamber of Commerce

The Nansen Center joins partnership with companies and organisations in the Norwegian-British Chamber of Commerce (NBCC).

 

Using reanalysis to detect eddies in the Mediterranean Sea

A new study was published this week in Frontiers in Earth Science, “Ocean Mesoscale Variability: A Case Study on the Mediterranean Sea From a Re-Analysis Perspective”. The study under the lead of Antonio Bonaduce includes Johnny A. Johannessen and Roshin P. Raj from NERSC, as well as colleagues from Italy and Germany.

 

What are mesoscale eddies?

A comprehensive Nansen Center contribution to the latest IPCC report

Works from 19 of our current researchers are used in the most recent IPCC report released on the 9th of August this year.

 

What NERSC will do onboard Statsraad Lehmkuhl during the One Ocean Expedition

Today, on August 20th, the tall ship Statsraad Lehmkuhl departs from Arendal and sets sail for the One Ocean Expedition. The Nansen Center will be part of this incredible journey.

Sixth Assessment Report WG1 contribution by IPCC published today!

Sebastian Mernild, our former director and now pro-rector and professor in climate change and glaciology at the University of Southern Denmark and in an adjunct position with us, is one of the Lead Authors contributing to the report!
