The objective of the project is the reconstruction of late Quaternary climate and landscape evolution on the Northern Tibetan Plateau. The project aims to contribute multidisciplinary approaches on three selected lake systems of quite different climate influence but with similar catchment characteristics. Different archives along sediment routings (sediment cascades) are studied in order to understand the impact of climate change on various land forming processes within well defined catchments. Research results from the Donggi Cona Basin obtained during the first funding period provide a strong interrelationship between lake catchment processes and the depositional environment during the last 20 ka, of which not all was affected by past monsoon climate. By reconstructing all interdependent processes, we will be able to synthesise land forming processes and their responses to climate forcing. We will provide a systematic chronostratigraphy of manifold aspects of environmental change on the northern Tibetan Plateau, combining different types of terrestrial and lacustrine records. Moreover, multiple analyses from the first period will be merged towards a comprehensive process-response model of environmental changes throughout the last 20 ka BP, applied to a newly developed statistic model by our group. In a second step we will continue research on the Lake Ayakhum farther west by using and improving the same approaches, successfully applied before.
