VENTILATE: Ventilation and remineralisation in polar and sub-polar regions as indicators for climate change

VENTILATE will evaluate decadal changes  in ventilation of the Nordic Seas (Greenland, Iceland, and Norwegian Seas) and the Arctic Ocean.

The oceans uptake of atmospheric CO2 is connected both to physical and biological processes. This uptake has been very important for the Earths climate, modulating the effect of man-made CO2 since the industrial revolution.

However, with the continuing increase of CO2 in the atmosphere and the observed climate change, it is uncertain how the ocean’s uptake will be affected in the future.

A key knowledge here is the link between the physical processes and the oceanic carbon cycle. To increase our understanding of this link is the overall aim of VENTILATE.

NORTH: NORthern constraints on the Atlantic ThermoHaline circulation

Structure of the Atlantic thermohaline circulation

Den atlantiske termohaline sirkulasjonen kan sies å være Golfstrømmens drivkraft, som en pumpe i den store globale havsirkulasjonen. Når Golfstrømmens forlengelse mot nord driver oppover langs vår kyst, avgir vannet varme til omgivelsene. Det blir avkjølt og tyngre. I De nordiske havene synker vannet ned og returnerer sørover igjen. 

Spørsmålet i dette forskningsprosjektet er enkelt sagt i hvilken grad vi kan si at klimaendringer i De nordiske hav er opphav til globale endringer, eller et resultat av globale endringer.

EuraArc: Impact of Arctic sea ice decline on Eurasian Climate

Link the Arctic sea ice and Eurasian climate

The satellite data over past 30 years indicated that the Arctic sea ice is decling fast. Furthermore, results from the CMIP3 and CMIP5 models showed that the summer Arctic sea ice will disapper at the end of 21st century.

ORGANIC: Overturning ciRculation and its implications for Global cArboN cycle In Coupled models

Overturning Circulation and its imapct on ocean carbon cycle

 

ORGANIC is a fundamental research project integrating mathematic, computational and natural

sciences, and is aimed at advancing our understanding of the climate system and identifying the

uncertainties associated with the future predictions. To do this, ORGANIC applies the Norwegian

Earth System Model (NorESM) to elucidate the variability and main drivers of the ocean conveyor

circulation, a key indicator for climate change. The implications of this variability on the

SNOWGLACE: The Changing Arctic Cryosphere: Snow and Sea Ice Impact On Prediction and Climate Over Europe and Asia

Climate impact of Arctic sea ice and snow cover

Arctic summer sea-ice extent exhibits a sharp declining trend, and the induced atmospheric warming at high latitudes in autumn has potentially important consequences for the climate of Europe and Asia. On the other hand, North America, Europe, and East Asia have experienced anomalously cold winters with record high snowfalls during some recent winters. The autumn snow cover over Eurasia is increasing, while in spring, the snow decline at high northern latitudes is the largest cryospheric change in terms of spatial extent.

NACLIM: North Atlantic Climate: Predictability of the climate in the North Atlantic/European sector

Impact of Arctic sea ice and sea surface temperature

 

NACLIM aims at investigating and quantifying the predictability of the climate in the North Atlantic/European

sector related to North Atlantic/Arctic sea surface temperature (SST) and sea ice variability and change on

seasonal to decadal time scales. SST and sea-ice forcing have a crucial impact on weather and climate in

BlueArc: Impact of ‘Blue Arctic’ on Climate at High Latitudes

Arctic sea ice impact on climate

 

The global warming is enhanced in the Arctic where surface air temperature has increased twice as much as the global average in recent decades, also called Arctic amplification. Arctic warming implies melting of sea ice, but its dynamic-thermodynamic response is neither straightforward

 

or necessarily linear, nor is the response of the atmosphere to sea ice

reductions. Satellite observations (1979 to present) show that the Arctic
