Stable Carbon Isotope Signature of Methane Released from Phytoplankton [Research Data]
Jun 7, 2023
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...

Application of concentration and 2-dimensional stable isotope measurements of methane to constrain sources and sinks in a seasonally stratified freshwater lake [data]

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...

Climate signals in stable carbon and hydrogen isotopes of lignin methoxy groups from southern German beech trees [data]

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...

Making plant methane formation visible – insights from application of 13C-labelled dimethyl sulfoxide [Research Data]

Methane (CH4) formation by vegetation has been studied intensively over the last 15 years. However, reported CH4 emissions vary by several orders of magnitude, thus making global estimates difficult. Moreover, the mechanism(s) for CH4 formation by plants is (are) largely unknown....

Methane cycling in a eutrophic lake characterised by multiple stable isotope and flux measurements [data]

Recent estimations demonstrate that methane (CH4) emissions from aquatic systems are responsible for up to half of global CH4 emissions. Lakes represent one of the largest CH4 sources, and emissions are predicted to increase due to global warming. However, there is a large uncert...
