Einzmann, Teresa; Schroll, Moritz; Kleint, Jan Frederik; Greule, Markus; Keppler, Frank, 2022, "Application of concentration and 2-dimensional stable isotope measurements of methane to constrain sources and sinks in a seasonally stratified freshwater lake [data]", https://doi.org/10.11588/data/KLFDVF, heiDATA, V1, UNF:6:v5med6vrABS01PP8hfg5JQ== [fileUNF]
Methane (CH4) emissions from aquatic systems have recently been comprised to account for up to 50 % of global CH4 emissions, with lakes representing one of the largest CH4 source within this pool. However, there is large uncertainty associated with CH4 emissions from freshwater e... |

Wieland, Anna; Greule, Markus; Roemer, Philipp; Esper, Jan; Keppler, Frank, 2022, "Climate signals in stable carbon and hydrogen isotopes of lignin methoxy groups from southern German beech trees [data]", https://doi.org/10.11588/data/ZCMVUY, heiDATA, V1, UNF:6:U4nXcHYDxhl9ro8YQIcHsA== [fileUNF]
Stable hydrogen and carbon isotope ratios of wood lignin methoxy groups (δ13CLM and δ2HLM values) have been shown to be reliable proxies of past temperature variations. Previous studies showed that δ2HLM values even work in temperate environments where classical tree-ring width a... |
