Nitrous Oxide (N2O) emission from Lake Geneva (LacNOx)
The project in a nutshell:
The LacNOX projects aims to characterize changes in the dissolved N2O along the water column at the LéXPLORE station, especially during metalimnetic CH4 accumulation. To measure both CH4 and N2O, we will conduct both the SubOcean and EXO Sonde profiling. It will allow precisely selecting the depths for discrete water sampling, making use of dissolved N2O, CH4 and O2 profiles, as well as turbidity, nitrate, and ammonia. We will also collect different nutrients and microbial samples, for further investigations related to the biogeochemical mechanisms generating the observed changes. We will also use the experiments to test new N2O and NH4 separating membranes, aiming to improve the SubOcean instrument performances.
