This project aims at synergising state of the art analytical sensing tools to the study of aquatic ecological processes with high spatial and temporal resolution in the field in order to understand planktonic biodiversity-productivity dynamics and their impacts on the local carbon cycle.Our long term vision is to develop a holistic analysis tool for environmental studies in real time. We propose to develop an aquatic ecosystem observatory on the basis of automated scanning flow-cytometry for the analysis of microorganisms in a lake through direct single particle observation after sampling at specific depths. The system will additionally feature on-line analysis of nutrients, micronutrients, and chemical parameters relevant to the carbon cycle, through the development of fluorescent sensing beads that are injected at the point of microorganism aspiration. The Sinergia-team proposes an interactive approach to develop and validate new chemical sensor technology for high-resolution monitoring in the field, which in turn will allow one to directly target key ecological questions: 1) Which variables influence short-term fluctuations in phytoplankton biodiversity and productivity triggering cyanobacterial blooms? 2) How do such shifts in biodiversity and blooms of inedible-toxic cyanobacteria affect the local carbon cycle?
