Anhäuser et al. (2014) explored the potential of δDeuterium analysis on bulk sediment and oospores from Characeae. The analysis of oospores will be soon extended in a cooperation with the Max Planck Institute for Chemistry, Mainz. Bandowe et al. (2014) were the first to do PAH analysis on ELSA sediments, mainly to develop a methodology to analyze past fire. Isotopes of sugar in the sediments of Gemündener Maar have been used by Hepp et al. (2016, 2019) to address a reconstruction of paleohumidity. Alkanes and GDGT paleotemperatures have been measured for 500 samples of the ELSA-20-Stack and will be presented by Martínez-García et al. in late 2021.
