Warm and wet, cool and dry? : molecular paleohydrology based on biomarker δD and δ18O across Central Europe since the Late…

A warmer climate is often described as a wetter climate, as warmer air can hold more moisture, leading to increased precipitation. However, the simple notion of “warm and wet” or “cool and dry” can be misleading, as seasonal changes in precipitation and evaporation are important for ecosystems. In Central…

Environmental controls on the distribution of GDGT molecules in Lake Höglwörth, Southern Germany

Tetraether lipids, such as glycerol dialkyl glycerol tetraethers (GDGTs), are an increasingly used proxy for reconstructing paleoclimatic and paleoenvironmental dynamics. On a global scale, environmental drivers controlling the distribution of GDGTs in lake systems have been described extensively. However,…

A 1100-year multi-proxy palaeoenvironmental record from Lake Höglwörth, Bavaria, Germany

Abstract Anthropogenic activities have exerted strong influence on ecosystems worldwide, particularly since 1950 CE. The local impact of past human activities often started much earlier and deserves detailed study. Here, we present an environmental record from a 278 cm long sedimentary core from Lake…

Summer paleohydrology during the Late Glacial and Early Holocene based on δ 2 H and δ 18 O from Bichlersee, Bavaria

Abstract Isotope-based records provide valuable information on past climate changes. However, it is not always trivial to disentangle past changes in the isotopic composition of precipitation from possible changes in evaporative enrichment, and seasonality may need to be considered. Here, we analyzed…

Mid to Late Holocene moisture evolution of semi-arid Mongolia and its anti-phase relationship with monsoonal Asia

The spatial and temporal interaction of the Westerlies and the Asian Summer Monsoon (ASM) are often suggested to drive the Holocene moisture evolution of semi-arid Mongolia and Central Asia, but so far, it has remained a controversial topic of debate. In this context, we established a high-resolution…
