LAC is a project funded by NERC, 2013-2016

The Arctic is warming rapidly, and the changes appear to be related to increasing greenhouse gas concentrations.  Currently the Arctic represents a store of carbon, held in peatlands and within the soils and sediments of permafrost-affected landscapes. As the Arctic warms and permafrost thaws carbon is released to the atmosphere, either as carbon dioxide or methane, through biological activity, which constitutes a large potential positive feedback to warming. The LAC (Lakes in the Arctic Carbon cycle) project focuses on how lakes focus carbon cycling in northern landscapes. Our study areas are Greenland, Alaska, and Norway.  The work involves collaboration between Loughboro, Nottingham, UCL and Southampton in the UK, and the University of Alaska, the National Park Service and the US Geological Survey in the US. We will use modern observations of lake carbon dynamics, records from lake-sediment cores, and remote-sensing to assess the role of arctic lakes in the carbon cycle and to upscale patterns of carbon production in different northern regions.

Southampton project participants: Prof. Mary Edwards, Dr. Pete Langdon, Dr. Jadu Dash, Dr. Maarten van Hardenbroek, Emma Hopla (PG doctoral student), Kassandra Reuss-Schmidt (PG Masters student).
