Klintzsch, Thomas; Geisinger, Hannah; Wieland, Anna; Langer, Gerald; Nehrke, Gernot; Bizic, Mina; Greule, Markus; Lenhart, Katharina; Borsch, Christian; Schroll, Moritz; Keppler, Frank, 2023, "Stable Carbon Isotope Signature of Methane Released from Phytoplankton [Research Data]", https://doi.org/10.11588/data/YYLEKU, heiDATA, V1, UNF:6:CUTgXYoCIx59M/OKIgTRvQ== [fileUNF]
Aquatic ecosystems play an important role in global methane cycling and many field studies have reported methane supersaturation in the oxic surface mixed layer (SML) of the ocean and in the epilimnion of lakes. The origin of methane formed under oxic condition is hotly debated a... |

Schneider, Marcus, 2023, "Gesteinsgebundene Gase in den Salzlagerstätten des Werra-Fulda-Kalireviers: Relevanz für die Lagerstättensicherheit und Einblick in die Bildung von Klimagasen und ozonzerstörenden Verbindungen bei Intraplattenvulkanismus [Forschungsdaten]", https://doi.org/10.11588/data/G6P9MK, heiDATA, V1, UNF:6:enOdBCCWPLeEEV7xTfiiGQ== [fileUNF]
The long mining history of the Werra-Fulda potash district is characterized by highly frequent gas-induced rocks burst during the extraction of potassium and magnesium salts. The gas was trapped by magmatic alterations of the Permian salt deposit during the Miocene Rhön volcanism... |

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... |
