Carbon and exchange from permafrost soils and ecosystems in Siberia

Research in the taiga and tundra ecosystems in eastern Siberia is performed in cooperative projects of the Institute for Biological Problems Cryolithozone (IBPC) of the Siberian Division of the Russian Academy of Sciences in Yakutsk and the Vrije Universiteit (VU) in Amsterdam (Department of Hydrology and Geo-Environmental Sciences) and Wageningen University (Nature Conservation and Plant Ecology).
In a larch/birch forest near Yakutsk (Spasskaya Pad Field Station) and on a tundra site near Chokhurdakh in the Indigirka lowlands (Kytalyk reserve) CO2 and CH4 flux measurements have been made with eddy correlation towers since respectively 2000 and 2003. The aim is to estimate the annual exchange rates and their interannual variability, and to determine the sensitivity to environmental factors and permafrost degradation. Currently, four publications resulting from this research are under review.
Finance for continuation of the research work at Chokurdagh until 2013 has been secured with new research grants from NWO (Dutch Organization of Scientific Research) and Darwin Center. This wil focus specifically on the effects of permafrost degradation on the carbon balance, effects of hydrological changes and vegetation-permafrost interactions. Research cooperation has been established with Japanese (Hokkaido University, Dr Iwahana) and German (AWI, Wetterich) research groups.
In november 2010, Wageningen University, IBPC, VU successfully organized the 5th International Workshop on' C/H2O/Energy balance and climate over boreal and arctic regions with special emphasis on eastern Eurasia', with contributions from Russia, Japan, Europe and USA.

The Willem Barentsz Polar legacy

When Willem Barentsz discovered Spitsbergen in 1596 he could never have imagined that more than 400 years later a Dutch Arctic research station would be established. This is the result of a research cooperation in the shape of the Willem Barentsz Polar Institute (WBPI), an institute for Arctic and Antarctic research. The WBPI wants to be a clear Dutch identity in the international field, enhance the co-operation between Dutch polar researchers and contribute to polar education and outreach activities. The WBPI has given a positive boost to new initiatives from the Netherlands in the polar areas, and serves a contact point of Dutch research in polar areas. More information you will find on our website: For any information you want to communicate with the Dutch polar network, or any questions, please do not hesitate to contact the co-ordinator of the Willem Barentsz Polar Institute, Annette Scheepstra.
