LAKES: Past, present and future of alpine lakes

Intersted in working on lakes physics or biogeochemistry. Available topics here.

Not one but two new papers on the drivers of planktonic communities in high-altitude lakes! Wonderful works led by Rocco Tiberti and Flavia Dory. Chech here.

Our final paper from CARBOGEN “Calcite precipitation: the forgotten piece of lakes’carbon cycle” ties it all together…. how to link calcite precipitation and lake CO2 emissions. What a journey, what a pleasure to finally get to the bottom of it. The paper comes with a great introduction by Jack Middelburg “Closing the inland water carbon cycle”.

Do not miss the episode “Zooplankton, those animals tricking the lake scientists”… Broadcasted on August 12th 2024…

Santona studied the origin of the methane that accumulates every summer at the thermocline of Lake Geneva. Methane is typically produced in anoxic conditions, in absence of oxygen. It is then puzzling to foind methane building up in the lake water column where oxygen is plentiful. Is this methane transported from the shore, where plenty of methane is produced in the anaerobic sediments? But is this even possible for such a large lake that methane gets transported over tens of kilometers? Instead, is this evidence for oxic methane production, a low-rate but demonstrated set of microbial pathways by which methane can be procuded in the presence of oxygen?
