Mechanical Modeling of Pre‐Eruptive Magma Propagation Scenarios at Calderas
(Journal of Geophysical Research: Solid Earth, 2023-02-24)Simulating magma propagation pathways requires both a well‐calibrated model for the stress state of the volcano and models for dike advance within such a stress field. Here, we establish a framework for calculating ... -
Mechanism for Deep Crustal Seismicity: Insight From Modeling of Deformation Processes at the Main Ethiopian Rift
(Geochemistry, Geophysics, Geosystems, 2020)We combine numerical modeling of lithospheric extension with analysis of seismic moment release and earthquake b-value in order to elucidate the mechanism for deep crustal seismicity and seismic swarms in the Main Ethiopian ... -
Mechanism of uranium fixation by zero valent iron: the importance of co-precipitation
(Uranium in the aquatic environment, 2002)The coprecipitation of U (VI) with iron corrosion products from aqueous solutions by zero valent iron was investigated. The evidence of coprecipitation was demonstrated by conducting experiments with well characterized ... -
Mechanism of uranium removal from the aqueous solution by elemental iron
(Journal of hazardous materials, 2006)The effectiveness of elemental iron (Fe0) to remove uranium (U) from the aqueous phase has been demonstrated. While the mitigation effect is sure, discrepancies in the removal mechanism have been reported. The objective ... -

Mediate relation between electrical and thermal conductivity of soil
(Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2020-08-03)Thermal conductivity is a key parameter for many soil applications, especially for dimensioning shallow and very shallow geothermal systems based on the possible heat extraction rate and for modelling heat transfer processes ... -
Mediterranean wetland conservation in the context of climate and land cover change
(Regional Environmental Change, 2020-06-02)Wetlands are known to support diverse and unique species assemblages. Globally, but particularly in the Mediterranean basin, they are threatened by climate change and natural habitat loss. Despite an alarming decline of ... -
Medium Energy Electron Flux in Earth's Outer Radiation Belt (MERLIN): A Machine Learning Model
(Space Weather, 2020-10-30)The radiation belts of the Earth, filled with energetic electrons, comprise complex and dynamic systems that pose a significant threat to satellite operation. While various models of electron flux both for low and relativistic ... -
Meeresspiegeldaten aus landschafts— und siedlungsgeschichtlichen Untersuchungen auf Pellworm (Nordfriesische Inseln)
(E&G – Quaternary Science Journal; Vol.30, No. 1)Es wird über archäologische, geographische und geologische Arbeiten zur Landschafts- und Besiedlungsgeschichte des südlichen nordfriesischen Wattenmeeres berichtet. Bei der Untersuchung von mittelalterlichen und frühneuzeitlichen ... -
Mega-monsoon variability during the late Triassic: Re-assessing the role of orbital forcing in the deposition of playa sediments in the Germanic Basin
(Sedimentology, 2019)The formation of the supercontinent Pangaea during the Permo–Triassic gave rise to an extreme monsoonal climate (often termed ‘mega-monsoon’) that has been documented by numerous palaeo-records. However, considerable debate ... -
Mega‐scale glacial lineations formed by ice shelf grounding in the Canadian Beaufort Sea during multiple glaciations
(Earth Surface Processes and Landforms, 2021-05-05)Mega‐scale glacial lineations formed by the raking of ice shelves across the seafloor have been reported from multiple polar regions. Here, we present the first evidence of continental slope situated buried lineations in ... -
Melt Production and Ejection From Lunar Intermediate‐Sized Impact Craters: Where Is the Molten Material Deposited?
(Journal of Geophysical Research: Planets, 2022-08-06)Differently aged impact melt in lunar samples is key to unveiling the early bombardment history of the Moon. Due to the mixing of melt products ejected from distant craters, the interpretations of the origin of lunar samples ... -
Melting Alpine Water Towers Aggravate Downstream Low Flows: A Stress‐Test Storyline Approach
(Earth's Future, 2023-03-27)Droughts can lead to extreme low flow situations in rivers, with resulting severe impacts. Upstream snow and ice melt in many of the world's mountain water towers can alleviate the hydrological consequences of drought, yet ... -
Melting Behavior of Rimed and Unrimed Snowflakes Investigated With Statistics of Triple‐Frequency Doppler Radar Observations
(Journal of Geophysical Research: Atmospheres, 2022-05-04)Comparing the reflectivity flux at the top and bottom of the melting layer (ML) reveals the overall effect of the microphysical processes occurring within the ML on the particle population. If melting is the only process ... -
Membrane Bioreactor–Treated Domestic Wastewater for Sustainable Reuse in the Lake Victoria Region
(Integrated Environmental Assessment and Management, 2020)Lake Victoria is a shared water resource between Kenya, Uganda, and Tanzania, which is the second largest freshwater lake in the world. It has long since suffered from the consequences of overexploitation of its resources, ... -
Menatanthus mosbruggeri gen. nov. et sp. nov. – A flower with in situ pollen tetrads from the Paleocene maar lake of Menat (Puy-de-Dôme, France)
(Palaeobiodiversity and Palaeoenvironments, 2020-11-16)The Paleocene Fossil-Lagerstätte Menat in France is well known for its wealth of outstandingly well preserved fossil insects and plants. Despite being known for more than a century, the palaeoflora, which is regarded as ... -
