Anthropogenic Heat Islands in the Arctic: Windows to the Future of the Regional Climates, Ecosystems, and Societies

The Arctic is a rapidly changing region where new economic opportunities meet geopolitical interests and the accelerated climate change. These three intertwined components concentrate in the arctic cities – a remote constellation of the cold frontier settlements, some of them as large as 300 thousands dwellers. The Arctic is rapidly urbanizing attracting worker migrants from southern latitudes, sometimes from as far south as Philippines (to Canada) and Tajikistan (to Russia).

New model simulations: Impact of algae content on the albedo and melting of snow on glaciers

The first physical model for the spectral ‘bioalbedo’ of snow, which predicts the spectral reflectance of snow packs contaminated with variable concentrations of red snow algae of varying size and pigment concentrations have been developed. The results have been published in the paper A predictive model for the spectral “bioalbedo” of snow by J.M. Cook (University of Sheffiled) et al., including Nansen Center CEO Prof.

110 polar scientists gathered in Bergen to kick-off the future observation system for the Arctic

The environment in Arctic region is now changing significantly due to increased temperature, thinning and decrease of the sea ice, melting of the Greenland Ice Sheet, thawing permafrost and changes in atmosphere and ocean circulation. Such changes have global as well as regional implications, including e.g.

110 polarforskere samles i Bergen for oppstart av framtidens observasjonssystem for Arktis

INTAROSINTAROS Økt interesse for og aktiviteter i Arktis krever ny forskning for å dekke kunnskapsbehovet om et Arktis i stadig endring.  Arktis er viktig for klima og har økende betydning i mange sammenhenger som næringsutvikling, transport og fiskerier. Observasjoner og målinger er vesentlig for å utvikle ny kunnskap om Arktis.

European needs for adaptation to changing sea level

The white paper Sea level related adaptation needs in Europe addresses the knowledge gaps related to European research and governance facing future changes in the sea level.

Satellite based study on the surface currents in the Indian Ocean

Based on the methods developed in his PhD studies The circulation of the Norwegian Sea - an investigation from space and ocean (2014) Dr. Roshin P. Raj has calculated the ocean surface current velocities in the Northern parts of the Indian Ocean.

New study: Weakening of North Atlantic current can be prevented by reducing carbon emissions

Nansen Center CEO Sebastian Mernild participates in an international study incorporating a comprehensive assessment of Greenland Ice Sheet melting suggesting that the freshwater influx could weaken the Atlantic Meridional Overturning Circulation (AMOC) over the next three centuries.

A new method for constraining the ocean in coupled system model for long reanalysis and climate predictions

Nansen and Bjerknes scientists have for the first time demonstrated the capability - thanks to an advanced data assimilation method - to constrain ocean variability in key regions (e.g. North Atlantic, Equatorial and North Pacific) of a fully coupled Earth system model just using sea surface temperatures. This result opens new possibilities for a long fully coupled reanalysis dating back to 1850 and test thoroughly the skills of decadal predictions by the Norwegian Climate Prediction model. The research team lead by Dr.

Summer School: “Crash Course on Data Assimilation - Theoretical foundations and advanced applications with focus on ensemble methods”

The Nordic Centre of Excellence Ensemble-based data assimilation for environmental monitoring and prediction - EmblA coordinated by the Nansen Center organises a 4-days summer school for PhD-level students and early stage scientists with beginner or no notions of data assimilation.
