PhD Project
The PhD is supervised by Prof. Dr. Gerold Wefer and Dr. Lydie Dupont
My thesis intended to bridge this gap with a high resolution study on climate and vegetation development in tropical Africa by means of palyonology on marine sediments of Ocean Drilling Site 1078 off the coast of Angola.
High resolution records from tropical regions are scarce and little exists for southern Africa.
Furthermore, a sensitive response of the vegetation in this part of the world is expected.
This thesis aims at a better understanding of abrupt climate changes in connection with the Atlantic overturning circulation and their global consequences.
The combination of pollen, as an indicator of environmental changes on the adjacent continent, and marine dinoflagellate cysts permit data for direct land-ocean correlation (Shi, Dupont et al. 2000).
By studying the Angolan vegetation of several Heinrich events, this PhD-thesis aim to gain insight in the variability and driving forces of the vegetation in Africa south of the equator.
Furthermore, there will be a comparison of the vegetation reconstruction based on the marine pollen record to model output in the form of plant functional types and literature of other high resolution studies of tropical records of the glacial period.
