A new publication in Journal of Glaciology reveals the importance of internal dynamical process in the abrupt changes of the Helheim and other glaciers at Greenland during the last 35 years. Nansen Center and Bjerknes Center scientists Victoria Miles, Martin Miles and Ola M. Johannessen have published the paper Satellite archives reveal abrupt changes in behavior of Helheim Glacier, southeast Greenland.
The project is devoted to improvement of lead fraction retrievals in the Arctic from satellites. These will then be used to study processes such as heat exchange between the ocean and the atmosphere and brine rejection during the ice formation.
Participants: N. Ivanova, P. Rampal, S. Bouillon, E. Ólason (NERSC), I. Fer, L.H Smedsrud (GFI), and M. Ilicak (Uni-Research)
DAMOCLES is an integrated ice-atmosphere-ocean monitoring and forecasting system designed for observing, understanding and quantifying climate changes in the Arctic.
DAMOCLES aims at reducing the uncertainties in our understanding of climate change in the Arctic and their impacts. The Arctic over the last 2-3 decades has warmed more than other regions of the world, and the sea-ice cover has decreased significantly in the same period. A first-order scientific and societal question is whether the Arctic perennial sea-ice will disappear in a few decades (or even faster, as predicted by some state-of-art climate models).
