Predictions of planets for 586 exosystems and a method for predicting planets in multi-planetary exosystems
(, 2019)We have applied a model of planetary system formation in the field of a standing sound wave (the ‘SSW-Model’) to the prediction of planets in 586 multi-planetary exosystems (384 biplanetary, 127 tri-planetary and 75 ... -
Ideas and perspectives: hydrothermally driven redistribution and sequestration of early Archaean biomass – the “hydrothermal pump hypothesis”
(Biogeosciences, 2018)Archaean hydrothermal chert veins commonly contain abundant organic carbon of uncertain origin (abiotic vs. biotic). In this study, we analysed kerogen contained in a hydrothermal chert vein from the ca. 3.5 Ga ... -
The Suitability of Pozzolan as Admixing Aggregate for Fe0-Based Filters
(Water, 2018)Continuous gravity-fed column experiments using the methylene blue (MB) discoloration method were performed to characterize the suitability of a pozzolan (PZ) specimen as alternative admixing aggregate for metallic iron ... -
Climate effects on vegetation vitality at the treeline of boreal forests of Mongolia
(Biogeosciences, 2018)In northern Mongolia, at the southern boundary of the Siberian boreal forest belt, the distribution of steppe and forest is generally linked to climate and topography, making this region highly sensitive to climate change ... -
Snowmobile impacts on snowpack physical and mechanical properties
(The Cryosphere, 2018)Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different ... -
Land Surface Temperature Variation Due to Changes in Elevation in Northwest Vietnam
(Climate, 2018)Land surface temperature (LST) is one of the most important variables for applications relating to the physics of land surface processes. LST rapidly changes in both space and time, and knowledge of LST and its spatiotemporal ... -

(TERRA NOSTRA - Schriften der GeoUnion Alfred-Wegener-Stiftung;2018,1)MTE13 is a showcase for the most up-to-date and groundbreaking research on Mesozoic terrestrial ecosystems and organisms. Presentations cover a wide variety of Mesozoic life, from protists to mammals, and Mesozoic ... -
A fossil species of the enigmatic early polypod fern genus Cystodium (Cystodiaceae) in Cretaceous amber from Myanmar.
(Scientific reports, 2017-11-06)The monospecific fern genus Cystodium (Cystodiaceae; Polypodiales) occurs exclusively in the tropical forests of the Malay Archipelago, the Admiralty Islands, the Louisiade Archipelago, and the Solomon Islands. Divergence ... -
Fast methane diffusion at the interface of two clathrate structures.
(Nature communications, 2017-10-20)Methane hydrates naturally form on Earth and in the interiors of some icy bodies of the Universe, and are also expected to play a paramount role in future energy and environmental technologies. Here we report experimental ... -
Tracing the oxygen isotope composition of the upper Earth's atmosphere using cosmic spherules
(Nature communications, 2017-06-01)Molten I-type cosmic spherules formed by heating, oxidation and melting of extraterrestrial Fe,Ni metal alloys. The entire oxygen in these spherules sources from the atmosphere. Therefore, I-type cosmic spherules are ... -
