The project in a nutshell
In this interdisciplinary project, we investigate the dynamic of primary production (PP) in Lake Geneva and other large lakes of Switzerland where phosphorous levels have declined drastically over the past decades. However, the resulting trends and variations of PP in space and time are not well understood. Our goals are (1) to improve and develop methods that quantify PP and demonstrate its spatiotemporal variability, (2) to identify the physical and biogeochemical drivers of PP from daily to annual time scale, and (3) to explain unexpected high PP in Lake Geneva despite decreasing nutrient levels.
