Lake snow – dynamics of the settling particulate matter in Lake Geneva
The project in a nutshell:
Holographic microscopy has become a powerful tool for in situ imaging of microscopic organisms and particles in lake environments. The submersible LISST-Holo2 camera is particularly effective for profiling particles between 25 μm and 2500 μm, enabling the identification of phytoplankton, small zooplankton, as well as organic and inorganic matter. This project aims to investigate the spatio-temporal dynamics of settling particulate matter (lake snow) in Lake Geneva, with a particular focus on understanding how the Rhône River plume influences particle flocculation and sedimentation processes.
