Hydrogen isotope ratios (2H/1H or δ2H) were measured in lipid biomarkers from algal, plant and microbial sources in sediment cores from a lake and a peat bog on the small, sparsely-inhabited Washington Island (4°43′N, 160°25′W) to assess centr

Empirical evidence suggested that the altitudinal dependence of hydrogen isotope ratios of leaf wax n -alkanes ( δ D wax ) can be used to estimate paleoaltitudinal changes. However, the application of δ D wax -based paleoaltimetry remains difficult

Summary Over the past decades, δ 18 O and δ 2 H analyses of lacustrine sediments became an invaluable tool in paleohydrology and paleolimnology for reconstructing the isotopic composition of past lake water and precipitation. However, based on δ 1

We measured dD values of long chain n-alkanes isolated from 30 surface soil samples along two elevation transects on the Tibetan Plateau differing in precipitation regime and water source. The East Asian Monsoon precipitation dominates the wetter reg

Compound-specific δD values of sedimentary n-alkanes from Nam Co were compared with oxygen isotope values from three different ice cores of the Tibetan Plateau and other climate proxies including temperature and solar radiation. This enabled estimat

This paper discusses the range of lake level changes, using hydro-acoustic techniques and sediment core data for Lake Nam Co in Central Tibet (China). This second largest Tibetan lake is situated at an elevation of 4718 m a.s.l. Lake level changes wi

For Lake Nam Co, south-central Tibetan Plateau, geomorphological features and hydrological characteristics have been compiled to provide an overview of the landscape character. Information is based on primary data, collected during field campaigns in

The hydrogen isotopic composition (δD) of leaf water used for biosynthesis of n-alkanes can be modified by climate. Therefore, the δD can be considered as potential paleoclimatic proxy to explore. We compared measured δD values of alkanes (n-C25 t

Compound-specific hydrogen isotope ratio values of lacustrine n-alkanes from two contrasting ecosystems, the semi-arid to arid Nam Co, Central Tibet and the humid Holzmaar, Germany, were compared in order to assess whether or not these environmental
