| Other Titles: | Kalzifizierung ausgewählter Coccolithophoridenarten: Strontium Partitionierung, Calcium Isotopenfraktionierung und Abhängigkeit von der Meerwasser Karbonatchemie | Authors: | Langer, Gerald | Supervisor: | Wolf-Gladrow, Dieter | 1. Expert: | Wolf-Gladrow, Dieter | Experts: | Riebesell, Ulf | Abstract: | This thesis investigates the response of two prominent coccolithophores, Coccolithus pelagicus and Calcidiscus leptoporus, to varying carbonate chemistry of seawater with special emphasis on calcification. The second issue of the present work is the assessment of coccolith-based proxies, in particular the Sr/Ca ratio and calcium isotope composition. This part focuses on Emiliania huxleyi. |
