Projects
Darwin project: Microbial carbon fixation in past and future high CO2 oceans
Carbon acquisition, allocation and processing by plankton in a high CO2-world
Atmospheric CO2 concentrations have already increased from ~280 to > 380 ppm during the Anthropocene and will increase further to 500-1250 ppm at the end of this century depending on the socio-economic scenario. Oceans take up a large part of the excess CO2 with the consequence that surface ocean water acidify. The biological consequences of ocean acidification are largely unknown, but important to investigate, because these changes are essentially irreversible during our lifetimes.
During my PhD, we’ll study the direct and indirect effects of high CO2 and low pH on natural plankton communities. We will make a cross-system analysis of phytoplankton characteristics, including elemental stoichiometry and isotopic composition. We will join in large-scale mesocosm experiments with manipulated CO2 levels and perform laboratory scale incubations with natural communities to investigate synergetic effects between high CO2 and elevated temperature and to study carbon isotope fractionation as a function of CO2. In stable isotope tracer experiments, we will study the transfer of carbon from carbon and nitrogen from primary producers to planktonic consumers as a function of CO2. Material of these studies will be used by our partners to develop and calibrate new proxies for CO2 and pH based on lipid composition of marine microbes.
