Journal ArticleDOI
An end-member algorithm for deciphering modern detrital processes from lake sediments of Lake Donggi Cona, NE Tibetan Plateau, China
Elisabeth Dietze,Kai Hartmann,Bernhard Diekmann,Janneke IJmker,Frank Lehmkuhl,Stephan Opitz,Georg Stauch,Bernd Wünnemann,Andreas Borchers +8 more
TL;DR: In this article, a flexible end-member modelling algorithm was proposed for the unmixing of grain-size distributions in the lake sediment data set, which is based on eigenspace analysis and considers inherent uncertainties.
Journal ArticleDOI
Holocene vegetation and climate of the Alashan Plateau, NW China, reconstructed from pollen data
TL;DR: In this article, a set of 55 recent pollen spectra from the Alashan Plateau and the Qilian Mountains (Qilianshan), northwestern China has been analyzed.
Journal ArticleDOI
Hydrological evolution during the last 15 kyr in the Tso Kar lake basin (Ladakh, India), derived from geomorphological, sedimentological and palynological records
Bernd Wünnemann,Bernd Wünnemann,Dieter Demske,Pavel E. Tarasov,Bahadur Singh Kotlia,Christian Reinhardt,Jan Bloemendal,Bernhard Diekmann,Kai Hartmann,Joachim Krois,Frank Riedel,Nidhi Arya +11 more
TL;DR: The Tso Kar lake basin in Ladakh, northwestern Himalayas (33°18′N, 78°E, 4527m a.s.a.s) is located close to the modern boundary of effective moisture transport from the Indian summer monsoon as mentioned in this paper.
Journal ArticleDOI
Sediment transport processes across the Tibetan Plateau inferred from robust grain-size end members in lake sediments
Elisabeth Dietze,Fabien Maussion,Marieke Ahlborn,Bernhard Diekmann,Kai Hartmann,Karoline Henkel,Thomas Kasper,Gregori Lockot,Stephan Opitz,Torsten Haberzettl +9 more
TL;DR: In this article, the main detrital processes that contribute to lacustrine sedimentation across the Tibetan Plateau using grain-size end-member modelling analysis are distinguished at different sites from similarly likely endmember model runs.
Journal ArticleDOI
Hydrological changes and Holocene climate variations in NW China, inferred from lake sediments of Juyanze palaeolake by factor analyses
Kai Hartmann,Bernd Wünnemann +1 more
TL;DR: In this article, the authors used principal component analysis (PCA) to extract the three system variables runoff, lake level/water budget and salinity as the major factors which have influenced the lake history during a highly variable Holocene climate.
