Active anaerobic methane oxidation and sulfur disproportionation in the deep terrestrial subsurface
Rizlan Bernier-Latmani, Manon Frutschi, Emma Bell, Chen Qian
Microbial life is widespread in the terrestrial subsurface and present down to several kilometers depth, but the energy sources that fuel metabolism in deep oligotrophic and anoxic environments remain unclear. In the deep crystalline bedrock of the Fennosc ...
2022Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland
Jana Freiin von Freyberg, Ilja van Meerveld
When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...
2021The modern analogue of a Cretaceous coral with a calcitic skeleton
Anders Meibom, Jaroslaw Hubert Stolarski
It was argued that, in contrast to all known modern scleractinian corals that form aragonite skeletons, the original mineralogy of the Cretaceous "Coelosmilia" (ca. 70-65 Ma) was calcite during a period when the Mg2+/Ca2+ ratio of the seawater was presumab ...
2019Sub-Ocean: Subsea Dissolved Methane Measurements Using an Embedded Laser Spectrometer Technology
The causes of the ∼80 ppmv increase of atmospheric carbon dioxide (CO2) during the last glacial.interglacial climatic transition remain debated. We analyzed the parallel evolution of CO2 and its stable carbon isotopic ratio (δ13CO2) in the European Project ...
American Geophysical Union (AGU)2018Solar-Driven High-Temperature Electrolysis Reactor for Fuel Processing
Solar-driven high-temperature electrolysis (HTE) and thermochemical cycles (TCC) are two promising pathways for fuel processing and energy storage, which are considered in this thesis. The goals of this thesis are: i) offering engineering guidelines at sys ...
EPFL2018Burial-induced oxygen-isotope re-equilibration of fossil foraminifera explains ocean paleotemperature paradoxes
Oxygen-isotope compositions of fossilised planktonic and benthic foraminifera tests are used as proxies for surface-and deep-ocean paleotemperatures, providing a continuous benthic record for the past 115 Ma. However, visually imperceptible processes can a ...
Springer Nature2017Aragonitic scleractinian corals in the Cretaceous calcitic sea.
Anders Meibom, Jaroslaw Hubert Stolarski, Stéphane Laurent Escrig
Changes in seawater chemistry have affected the evolution of calcifying marine organisms, including their skeletal polymorph (calcite versus aragonite), which is believed to have been strongly influenced by the Mg/Ca ratio at the time these animals first e ...
Geological Soc Amer, Inc2016Mixed strain-displacement finite elements for landslide and avalanche release prediction
Determination of the initial detaching volume is one of the major challenges in snow avalanche and debris flow forecast. Soil liquefaction due to loss of cohesion results in landslides, whereas quasi-brittle failure triggers the release of snow avalanches. ...
2015Unusual Micrometric Calcite–Aragonite Interface in the Abalone Shell Haliotis (Mollusca, Gastropoda)
Species of Haliotis ~abalone! show high variety in structure and mineralogy of the shell. One of the European species ~Haliotis tuberculata! in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
