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).
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 snowby J.M. Cook (University of Sheffiled) et al., including Nansen Center CEO Prof.
Nansen Center scientists, lead by scientist Dr. Jiping Xie, have published a comprehensive quality assessment of the TOPAZ4 ocean and sea ice model reanalysis for the North Atlantic and Arctic oceans in Ocean Sciences.

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.

INTAROS 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.

Ambassador Nils Ragnar Kamsvaag, secretary Ragnhild Vognild from the Norwegian Embassy and staff and students at NERCI in Cochin.His Excellency Mr Nils Ragnar Kamsvaag ambassador of Norway to India and Mrs Ragnhild Vognild, Secretary at the Norwegian Embassy visited the office of the Nansen Envrionmental Research Centre (NERCI) in Cochin on the 14th December. The visitors were received by Dr. Ajith Joseph, Director, Prof. N. R. Menon, Chairman of Board and Dr. Nandini Menon, Deputy Director.
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.
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.
