Schroll, Moritz, 2022, "Methane cycling in a eutrophic lake characterised by multiple stable isotope and flux measurements [data]", https://doi.org/10.11588/data/MU3CON, heiDATA, V1, UNF:6:uMXNN9yPRjWKSRIzJA3uuA== [fileUNF]
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... |

Klintzsch, Thomas; Keppler, Frank, 2019, "Methane production by three widespread marine phytoplankton species: release rates, precursor compounds, and potential relevance for the environment [Dataset]", https://doi.org/10.11588/data/9N1LSR, heiDATA, V1, UNF:6:dxf+QSeRKu9v6uPyAUhX8Q== [fileUNF]
We investigated marine algae as a source of methane (CH4) in oxic surface waters of oceans. The widespread haptophytes Emiliania huxleyi, Phaeocystis globosa and Chrysochromulina sp. were investigated. We performed CH4 production and stable carbon isotope measurements and provide... |
