Understanding And Predicting Coccolithophorid Calcification In A Changing Ocean, Natasha Aisha Gafar Jan 2018

Understanding And Predicting Coccolithophorid Calcification In A Changing Ocean, Natasha Aisha Gafar

Theses

My project builds on previous work to derive a new biologically based model to describe the response of coccolithophorid growth, photosynthesis and calcification to changing carbonate chemistry (pCO2), which, also accounts for the effects of temperature and light. This model, was used to increase understanding of the interacting effects of light, temperature and CO2 on the two key coccolithophores Emiliania huxleyi and Gephyrocapsa oceanica. I also examined how changing light and pCO2 influenced the large coccolithophore Scyphosphaera apsteinii through both experiments and the application of the above model.
