- Abstract:
- Charophyte algae develop calcite (CaCO3) incrustations on their stems and oospores as the result of photosynthesis, forming thick deposits of marl in lakes and characteristic oospore fossils (gyrogonites). The stable C and O isotope composition of the calcite provides information on the environment in which the calcite was precipitated but a deeper understanding of the calcification process is needed before they can be fully interpreted. We will test two models of charophyte calcification using microsensors and H14CO3-tracer. The reliability of the Chara calcite C & O stable isotopes as environmental indicators will be determined by monitoring in detail a small Chara lake over a one-year period.
