Session description:

Due to potential impacts and feedback mechanisms on the Earth system dynamics of permafrost carbon, nitrogen (and other nutrients) as well as contaminants have become a focal point in sub-Arctic and Arctic research.

Permafrost deposits, including ground-ice, are vulnerable to active layer deepenig as well as surface subsidence and erosion. These processes may lead to landscape changes that affect both shallow and deep frozen stocks of carbon, nitrogen and contaminants. The remobilization of these may lead to global climate feedbacks and local to regional changes in ecosystem functioning, but it may also have more direct impacts on local communities’. Thus, there is an urgent need to enhance the understanding of the consequences of permafrost thawing and the fate of the liberated former frozen elements of permafrost across spatial and temporal scales.

In this session, we invite studies about permafrost carbon, nutrients and contaminants (may include organic and inorganic contaminants, from natural or anthropogenic sources) in permafrost. We are intesrested in any study that relates to their quantity, properties or their fate in a changing Arctic. This includes a variety of methods like sediment based work, hydrological measurements, remote sensing and modelling, as well as interdisciplinary studies on the stock and fate of carbon, nutrients and contaminates for assessing local, regional, and global impacts.
