Microphysical Pathways Active Within Thunderstorms and Their Sensitivity to CCN Concentration and Wind Shear
; (Journal of Geophysical Research: Atmospheres, 2023-03-01)
The impact of cloud condensation nuclei (CCN) concentration on microphysical processes within thunderstorms and the resulting surface precipitation is not fully understood yet. In this work, an analysis of the microphysical ... -
Microplastics as a sedimentary component in reef systems: A case study from the Java Sea
; ; ; (Sedimentology, 2021-06-12)
Microplastic pollution has been reported from coral reef systems all over the tropics. Exposure to microplastics has several negative impacts on coral health, such as bleaching, tissue necrosis, or an impairment of the ... -
Microseismicity and Lava Flows Hint at Magmato‐Tectonic Processes Near the Southern Tip of the Fonualei Rift and Spreading Center in the Lau Basin
; Cremanns, M.; ; ; ; (Journal of Geophysical Research: Solid Earth, 2021-04-27)
Spreading centers in the proximity of back‐rolling subduction zones constitute an ideal natural laboratory to investigate the interaction of magmatism and tectonism during the early evolution of back‐arc basins. Using ... -
Microsites and early litter decomposition patterns in the soil and forest canopy at regional scale
; ; (Biogeochemistry, 2020-10-13)
Plant litter decomposition is a key ecological process that is mostly studied at the forest floor. However, decomposition generally starts in the canopy. In this study, we evaluated the effect of litter composition and ... -
Microstructural analysis of the RWTH-1 cores in thinsections

Microstructural criteria for synseismic loading and postseismic creep in the uppermost plastosphere - an example from the Sesia Zone, Western Alps
(Univ. Bochum, 2002)
Anhand des Modellfalls der Sesia Zone in den West-Alpen werden mikrostrukturelle Kriterien für syn- und postseismische Deformation in der oberen Plastosphäre in Folge eines großen Erdbebens in der überlagernden Schizosphäre ... -
Microstructural evidence of impact-induced crystalplastic deformation and postshock annealing of quartz
; Spray, John G. (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
During impact, rocks at the surface and accessible depths encounter extreme conditions. The hydrostatic component of the shock wave-associatedstress, the so-called shock pressure, canreach several tens of GPa in the central ... -
Microstructures of fibrous halite veins
; Pennock, Gill; Schléder, Zsolt; Burliga, Stansilaw; (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Halite veins hosted in clastic sedimentary rocks are frequently observed next to evaporite layers. Their microstructure can be enhanced by gamma irradiation and etching, which can be used to infer the deformation mechanism of ... -
Mid-chain branched alkanoic acids from "living fossil" demosponges: a link to ancient sedimentary lipids?

Mid-chain branched alkanoic acids from "living fossil" demosponges: a link to ancient sedimentary lipids?
; Jenisch, Angela; ; Löwenberg, Antje; ; Michaelis, Walter (Organic geochemistry, 1999)
The lipid assemblages of the "living fossil" stromatoporoid Astrosclera willeyana (Great Barrier Reet) and the demosponge Agelas aroides (Mediterranean Sea) were investigated. Large amounts of branched carboxylic acids ... -
Mid-infrared reflectance spectroscopy of aubrite components
; ; ; Sohn, Martin; ; ; ; Helbert, Joern (Meteoritics & Planetary Science, 2020)
Aubrites Peña Blanca Spring and Norton County were studied in the mid-infrared reflectance as part of a database for the MERTIS (Mercury Radiometer and Thermal Infrared Spectrometer) instrument on the ESA/JAXA BepiColombo ... -
Mid-infrared spectroscopy of alkali feldspar samples for space application
; ; ; ; ; (Mineralogy and Petrology, 2020-07-30)
Feldspars are major components of terrestrial planetary surfaces. For future space application and the setup of a comprehensive reference database, Na- and K-rich alkali feldspars, NaAlSi3O8 – KAlSi3O8, have been investigated ... -
Middle and Late Devonian paleogeography of the eastern Anti-Atlas (Morocco)
(International Journal of Earth Sciences, 2021-04-17)
The eastern Anti-Atlas of Morocco represents one of the most completely exposed and perfectly documented biostratigraphic records of the entire Devonian worldwide. Paleogeographically it is clearly differentiated into ... -
Middle Miocene Climate and Stable Oxygen Isotopes in Europe Based on Numerical Modeling
; ; ; ; ; ; ; ; ; ; (Paleoceanography and Paleoclimatology, 2022-10-24)
The Middle Miocene (15.99–11.65 Ma) of Europe witnessed major climatic, environmental, and vegetational change, yet we are lacking detailed reconstructions of Middle Miocene temperature and precipitation patterns over ... -
