The project in a nutshell
A central yet overlooked mechanism of horizontal transport in lakes is the buoyancy-driven nearshore flows (thermal syphons) resulting from night time cooling. This process transports littoral water into the pelagic zone. By shifting oxygen, nutrients and carbon from the littoral to the pelagic waters, such lateral fluxes have major biogeochemical implications.
This project aims at investigating the role of these thermal syphons in a high altitude small lake and a large low land lake. The approach combines extensive in situ observations analyzed with numerical models.
