6. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions
Sammanfattning : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. LÄS MER
7. The atmospheric contribution to Arctic sea-ice variability
Sammanfattning : The Arctic sea-ice cover plays an important role for the global climate system. Sea ice and the overlying snow cover reflect up to eight times more of the solar radiation than the underlying ocean. Hence, they are important for the global energy budget, and changes in the sea-ice cover can have a large impact on the Arctic climate and beyond. LÄS MER
8. Nitrate stable isotopes and major ions in snow and ice from Svalbard
Sammanfattning : Increasing atmospheric reactive nitrogen (Nr), as consequence of human activities, has generated accumulation of nitrate (NO3-) in Arctic regions. The Arctic has fragile nitrogen limited ecosystems that can be altered by increases of dry or wet deposition of Nr. LÄS MER
9. Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export
Sammanfattning : The sea ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, along-isopycnal upwelling of warm, carbon-rich circumpolar deep water coincides with the annual growth and melt of Antarctic sea ice that represents one of the worlds largest surface water transformations.

10. Climatology and firn processes in the lower accumulation area of the Greenland ice sheet
Sammanfattning : The Greenland ice sheet is the largest Northern Hemisphere store of fresh water, and it is responding rapidly to the warming climate. In situ observations document the changing ice sheet properties in the lower accumulation area, Southwest Greenland. LÄS MER
