LAKES: Past, present and future of alpine lakes
Institute of Earth Surface Dynamics
Juliette Marot, a Master’s student from the ENTPE, France, works on the impact of the snow water equivalent and snow melt on the heat balance of high altitude lakes. A great but demanding field work but certainly not a problem for Juliette.

In a new paper led by Nico, we show that calcite precipitation, a process that is totally overlooked in carbon cycle studies, can generate as much carbon fluxes as the net ecosystem productivity for Lake Geneva. Results from a super-time resolved dataset collected over two years on LéXPLORE. The paper is in press for STOTEN, fully open access and can be found here.
Using remote sensing and machine learning, Gael could reconstruct the dynamics of whitings on Lake Geneva from the mid XXth century up to now. There is no clear trend in the annual number of whiting days over the latest 70 years. However, whitings appears now sooner, and Spring is now the whiting season, instead of summer.

Isabel won the Limnology Poster Award at the SGM 2022, Nicolas and Gael gave great talks.
Congratulations Everyone
Since September, we welcome in our group Dr Santona Khatun. Santona obtained the Dean’s post-doctoral fellowship for her project on the origin of the metalimnetic methane in Lake Geneva. She is working in both the Lakes’ group and Prof. Berg’s group. She came a long way, over from Bangladesh but she started field work as soon as arrived in Switzerland. Check her profile!
