The Vrije Universiteit in Amsterdam (Han Dolman), in collaboration with the Institute for Biological Problems of Cryolithozone of the Siberian Division of the Russian Academy of Sciences in Yakutsk, is performing studies on the carbon and water exchange of larch and tundra ecosystems on permafrost. Measurements are taken by means of micrometeorological techniques above a larch forest in Yakutsk and a tundra site in the Far North near Chokurdakh. The aim is to estimate the annual exchange rates and determine the sensitivity to environmental factors.
