Phytoplankton are micrscopic marine plants (algae) that float around in the water column. They photosynthesis, so take in CO2 and release O2, just like land plants.
We are interested in the abundance and diversity of phytoplankton in the different mesocosms and whether this changes in conditions of ocean acidification. We are also interested in primary production, formation of particles – such as transparent exopolymer particles (TEPs), comassie-stainable particles (CSPs) – and how active they are. We are interested in the interactions between phytoplankton and viruses, phytoplankton and zooplankton, and phytoplankton and nutrients.
