Sparse palaeoenvironmental data from the north-eastern Tibetan Plateau revealed that thisarea partly contradicts the general pattern of late Quaternary effective moisture change knownfrom other monsooninfluenced areas. Our project aims to investigate the causes andconsequences of regional moisture change on NE Tibetan Plateau. On the basis of severalfieldwork surveys (including a detailed lake basin survey) on the NE Tibetan Plateau andpreliminary palaeoecological data, we have selected three coring sites in the Lake DonggiCona basin (35.3°N; 98.6°E: 4100 m asl.) to explore the circumstances of regional effectivemoisture changes. Within the frame of this application we plan to retrieve three sedimentcores from the lake and prepare the sediment material for further analysis.
