Water isotope facility

Our water isotope facility comprises a stable isotope analyser for water vapour and liquid water samples and a multiplexed vacuum distillation line.

More information on our water isotope facility can be found here.

We have also recently built a fog collector for water isotope analysis that we will use in our project HydroBeech.

 

Gas lab facility

IMG_1383

Our gas lab facility is comprised of a suite of different laser spectroscopy analysers for measuring stable isotope ratios in CO2, water vapour and liquid water, as well as OCS. We also have different systems for automatic measurements of gas exchange on soil monoliths or single leaves in the lab or on soil plots or branches in the field. The lab is also equipped with three climate-controlled chambers for acclimating soil microcosms or entire plants. You will find more information on our soil gas exchange systems here. More information on our leaf gas exchange systems are also available there.

Field sites

Most of our research is conducted in the field, in multi-instrumented sites to understand the response of terrestrial ecosystems to climate change and extreme climatic events.

Ecosystem modelling

MuSICA_general_diagram

The EcoFun team has also a strong expertise in the modelling of micrometeorological and ecophysiological processes involved in the biogeochemical cycling of energy, water and carbon within soils and vegetation canopies. In particular, the team develops the ecosystem-scale model MuSICA that describes how energy, water, CO2 and other trace gases (ozone, COS, CO2 and water isotopes) are being exchanged within complex canopies comprising multiple species and vegetation layers.
