Schroll, Moritz; Lenhart, Katharina; Greiner, Steffen; Keppler, Frank, 2022, "Making plant methane formation visible – insights from application of 13C-labelled dimethyl sulfoxide [Research Data]", https://doi.org/10.11588/data/VJFIBD, heiDATA, V1, UNF:6:1Pzn25XuesxTt+Ygdeo4vg== [fileUNF]
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.... |

This repository contains data, figures and tables created for the paper "Mapping physical access to healthcare for older adults in sub-Saharan Africa: A cross-sectional analysis with implications for the COVID-19 response", which is currently under review and available as preprin... |
Ludwig, Christina; Hecht, Robert; Lautenbach, Sven; Schorcht, Martin; Zipf, Alexander, 2020, "Mapping Public Urban Green Spaces based on OpenStreetMap and Sentinel-2 imagery using Belief Functions: Data and Source Code", https://doi.org/10.11588/data/UYSAA5, heiDATA, V1, UNF:6:+pceldpLQoaQQqPk4/t1VQ== [fileUNF]
Public urban green spaces are important for the urban quality of life. Still, comprehensive open data sets on urban green spaces are not available for most cities. As open and globally available data sets the potential of Sentinel-2 satellite imagery and OpenStreetMap (OSM) data... |

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... |
