The recent years have seen a number of dramatic changes in the Arctic cryosphere. Some of these changes have exceeded the most aggressive projections, such as the record melt of sea ice in summer 2007, the major melt off around the edges of the Greenland Ice Sheet and extensive and previously unrecognized releases of greenhouse gases from terrestrial permafrost in the off-season and from the shallow sub-sea permafrost on the Siberian-Arctic shelf.
The climatic feedbacks from a changing cryosphere are complex. They vary over space and time, and are generally poorly understood. The NCoE DEFROST seeks to fill critical gaps in concepts and information, and to incorporate this understanding into models that reduce uncertainties.
The NCoE DEFROST will gather internationally recognized experts with the goal of understanding how changes in the cryosphere caused by climate change influence the ecosystem/geosphere processes which directly affect climate.
The centre seeks to bridge existing gaps between climate modelling, cryospheric science, and Arctic ecosystem science. The center will exploit Nordic, world leading capacity and provide a platform for wider international collaboration and high visibility of top-level Nordic research in both European and global contexts.
We have in DEFROST generally contributed as planned to the overall directions set out by our objectives. We have published from the central coordination part in discussions in Nature and have also contributed to the visibility internationally of DEFROST through a recent commentary also in Nature mentioning the important contribution of this Nordic cross-diciplinary Top-Level Research Initiative. Several results from our studies of cryospheric-climate interactions ranging from landbased studies over lakes and rivers through the near coastal realm to sea ice dynamics have already been published in high-impact journals and many more are on the way.
