Installation of bottom breathing chambers for Q-Arctic
Global warming is most pronounced in the Arctic region. The release of greenhouse gases from Arctic soils is increasing due to global warming. This may turn the Arctic from a carbon sink to a future source. Two young scientists from Matthias Göckede's research group are studying this topic and plan to install soil respiration chambers in northern Canada for this purpose.
The ERC-funded Q-Arctic Synergy Grant (2011-2027) will develop a next-generation coupled land surface model.
Unfortunately the trip was not under a good star, already before the trip there were visa problems and in the run-up a part of the research group fell ill and then also some on site. Nevertheless, a smaller team was able to install a measuring transect with the support of Canadian colleagues.

Measurement of the fluxes of carbon dioxide, methane and water vapor using a transparent chamber. Here, a dark measurement is performed by covering the chamber with a light-tight hood. A portable LI-7810 gas analyzer and a portable measurement system for accompanying measurements (air temperature, humidity, air pressure in the chamber, photosynthetically active radiation, soil temperatures and soil moistures) are used.
