Deepening the Late Quaternary's Deep Ocean Carbon Mysteries
(
- Geophysical Research Letters
, 2022-07-06)
Changes to the carbon content of the deep ocean, the largest reservoir in the surficial carbon cycle, are capable of altering atmospheric carbon dioxide concentrations and thereby Earth's climate. While the role of the ...
MAGEMin, an Efficient Gibbs Energy Minimizer: Application to Igneous Systems
(
- Geochemistry, Geophysics, Geosystems
, 2022-07-18)
Prediction of stable mineral equilibria in the Earth's lithosphere is critical to unravel the tectonomagmatic history of exposed geological sections. While the recent advances in geodynamic modeling allow us to explore the ...
Robust approaches for model‐free small‐angle scattering data analysis
(
- Journal of Applied Crystallography
, 2022-05-28)
The small‐angle neutron scattering data of nanostructured magnetic samples contain information regarding their chemical and magnetic properties. Often, the first step to access characteristic magnetic and structural length ...
Temporal evolution of headwall erosion rates derived from cosmogenic nuclide concentrations in the medial moraines of Glacier d'Otemma, Switzerland
(
- Earth Surface Processes and Landforms
, 2022-05-03)
Climate change affects the stability and erosion of high‐alpine rock walls above glaciers (headwalls) that deliver debris to glacier surfaces. Since supraglacial debris in the ablation zone alters the melt behaviour of the ...
Benthic Carbon Remineralization and Iron Cycling in Relation to Sea Ice Cover Along the Eastern Continental Shelf of the Antarctic Peninsula
(
- Journal of Geophysical Research: Oceans
, 2022-06-28)
Rapid and profound climatic and environmental changes have been predicted for the Antarctic Peninsula with so far unknown impact on the biogeochemistry of the continental shelves. In this study, we investigate benthic ...
Microbially promoted calcite precipitation in the pelagic redoxcline: Elucidating the formation of the turbid layer
(
- Geobiology
, 2022-05-05)
Large bell‐shaped calcite formations called “Hells Bells” were discovered underwater in the stratified cenote El Zapote on the Yucatán Peninsula, Mexico. Together with these extraordinary speleothems, divers found a white, ...
High‐resolution facies analysis of a coastal sabkha in the eastern Gulf of Salwa (Qatar): A spatio‐temporal reconstruction
(
- Sedimentology
, 2021-10-12)
Abstract
Sabkhas are key landforms along the southern coast of the Arabian Gulf and represent modern analogues for depositional and diagenetic processes controlling properties and quality of ancient hydrocarbon‐bearing ...
Formation of fused aggregates under long‐term microgravity conditions aboard the ISS with implications for early solar system particle aggregation
(
- Meteoritics & Planetary Science
, 2022-04-21)
In order to gain further insights into early solar system aggregation processes, we carried out an experiment on board the International Space Station, which allowed us to study the behavior of dust particles exposed to ...
Crystallographic analysis of the lattice metric (CALM) from single electron backscatter diffraction or transmission Kikuchi diffraction patterns
(
- Journal of Applied Crystallography
, 2021-05-28)
A new software is presented for the determination of crystal lattice parameters from the positions and widths of Kikuchi bands in a diffraction pattern. Starting with a single wide‐angle Kikuchi pattern of arbitrary ...
Deformation, CPO, and Elastic Anisotropy in Low‐Grade Metamorphic Serpentinites, Atlantis Massif Oceanic Core Complex
(
- Geophysical Research Letters
, 2021-04-28)
Crystallographic preferred orientation (CPO) and the associated seismic anisotropy of serpentinites are important factors for the understanding of tectonic settings involving hydrated Earth´s mantle, for example, at ...
