LAKES: Past, present and future of alpine lakes
Institute of Earth Surface Dynamics
The “floating lab” being assembled on the Eastern shore of Lake Geneva, and ready to get anchored in front of Pully, inside the secured perimeter.
We are all quite eager to start working from the platform.
That was not easy but the full team finally managed to set up a brant new Campbell weather station at lake Muzelle, along with a new and more efficient settlement of the mooring. Some were so happy that they were surprised singing “Il était un petit navire” while rowing on the new boat…. We were also lucky enough to have it played at the “cor de chasse”.
Marttiina Rantala has joined the team earlier this month for a one-year post-doc. She got her project on long-term changes in peri-alpine lakes CO2 funded by the “confederation Suisse”. Welcome Marttiina!
“Tipping points” and “regime shifts” are two qualifiers often used to characterize any abrupt change in an ecosystem state over time. True regime shifts imply non linearity, hysteresis and lack of resilience but not every ecological transition is, hopefully, a regime shift. In the line of Rosalie’s Work, this paper explores how to confidently detect regime shifts from sediment archives.
