Abstract
Summary
To follow climate change in sediment cores it is important to now how quick a biomarker reacts to climate change. Here we investigated a sediment core from Lake Van retrieved during an ICDP campaign in 2021. We compare compound specific hydrogen isotopes measurements on biomarkers, i.e. long-chain n-alkanes and alkenones to understand which biomarker reacts first to, in this case, the water cycle (precipitation, evaporation) in the Eastern Turkey area.
