Stability and Variations of Arctic Land Ice - SVALI
Stability and Variations of Arctic Land Ice (NCoE - SVALI) is a Nordic Centre of Excellence (NCoE), which aims to improve our understanding of stability, variations and dynamics of the cryosphere. The centre was appointed in June 2010 by Nordforsk under Top-level research. Department of Geosciences, participate with research projects and in the management of the centre, which is a collaboration between 18 research institutions from all the Nordic countries.

About the group
Global warming causes changes in the cryosphere - that is all frozen water on the Earth's surface (ice, snow, tele, permafrost and ice-covered water). A warmer climate leads to an ever-increasing flow of meltwater and icebergs from glaciers on land into the ocean. This leads to a rising sea level. Also the level of fresh water in the oceans is increasing and affecting ocean circulation and the hydrological cycle in the Arctic.
These changes are happening more rapidly than predicted. In order to be able to foresee future sea level rise, it is necessary to strive for a better understanding of glaciological processes, and to include them in Earth System Models.
Several researchers and PhD students from the Department of Geosciences participate in the research included in SVALI. In addition to this research group described here two other groups have relevant research in the Arctic and cryosphere field, see the research groups:
More about the Nordic Centre of Excellence SVALI
Nordic researchers are uniquely positioned to play a leading role in this research, and NCoE - SVALI will constitute a platform for joint process studies, analyses, sharing of methods, researcher training and outreach activities to spread information about the scientific results.
NCoE - SVALI aims to answer these questions:
- How fast is land ice volume in the Arctic and North-Atlantic area changing, and why?
- Will these processes continue to accelerate?
- What are the consequences for sea-level and ocean circulation
- What are the implications for society?

A total of 18 Nordic partners will study basic processes of remote sensing (GIS), airborne and in-situ measurements, and carry out advanced Earth System modeling, focusing on glaciers in the Arctic and the North Atlantic area. Ultimately, the Centre will form a common foundation for international collaboration of Nordic scientists in cryospheric research.See the full list of partners in SVALI.
