M2 Internal-Tide Generation in STORMTIDE2
; (Journal of Geophysical Research: Oceans, 2020)
Internal-tide generation has been quantified using both pressure work and energy conversion. When calculating the pressure work from simulated or observed data, the internal-tide pressure has to be decomposed from the full ... -
Machine learning based identification of dominant controls on runoff dynamics
; Schumann, Andreas H. (Hydrological Processes, 2020-03-16)
Hydrological models used for flood prediction in ungauged catchments are commonly fitted to regionally transferred data. The key issue of this procedure is to identify hydrologically similar catchments. Therefore, the ... -
Machine learning for scattering data: strategies, perspectives and applications to surface scattering
(Journal of Applied Crystallography, 2023-01-24)Machine learning (ML) has received enormous attention in science and beyond. Discussed here are the status, opportunities, challenges and limitations of ML as applied to X‐ray and neutron scattering techniques, with an ... -
Machine Learning‐Based Prediction of Spatiotemporal Uncertainties in Global Wind Velocity Reanalyses
; Saynisch‐Wagner, Jan; Thomas, Maik (Journal of Advances in Modeling Earth Systems, 2020-05-13)
The characterization of uncertainties in geophysical quantities is an important task with widespread applications for time series prediction, numerical modeling, and data assimilation. In this context, machine learning is ... -
Macrofauna as a major driver of bentho‐pelagic exchange in the southern North Sea
; van Beusekom, Justus E. E.; Eisele, Annika; Emeis, Kay‐Christian; Friedrich, Jana; Kröncke, Ingrid; Logemann, Ella Lu; Meyer, Julia; Naderipour, Céline; Schückel, Ulrike; Wrede, Alexa; Zettler, Michael L. (Limnology and Oceanography, 2021-05-06)
The contribution of sediments to nutrient cycling of the coastal North Sea is strongly controlled by the intensity of fluxes across the sediment water interface. Pore‐water advection is one major exchange mechanism that ... -
Macroporosity and Grain Density of Rubble Pile Asteroid (162173) Ryugu
; ; ; ; ; Sakatani, Naoya; ; ; ; Honda, Chikatoshi (Journal of Geophysical Research: Planets, 2020-12-04)
Rubble pile asteroids such as (162173) Ryugu have large bulk porosities, which are believed to result from void spaces in between the constituent boulders (macroporosity) as well as void spaces within the boulders themselves ... -
Mafic explosive volcanism at Llaima Volcano: 3D x-ray microtomography reconstruction of pyroclasts to constrain shallow conduit processes
; ; ;; (Bulletin of Volcanology, 2021-12-06)
Mafic volcanic activity is dominated by effusive to mildly explosive eruptions. Plinian and ignimbrite-forming mafic eruptions, while rare, are also possible; however, the conditions that promote such explosivity are still ... -
Mafic Late Miocene–Quaternary volcanic rocks in the Kamchatka back arc region: implications for subduction geometry and slab history at the Pacific–Aleutian junction
Volynets, Anna; Churikova, Tatiana;; Gordeychik, Boris; Layer, Paul (Contributions to Mineralogy and PetrologyContributions to Mineralogy and Petrology, 2009)
New 40Ar/39Ar and published 14C ages constrain voluminous mafic volcanism of the Kamchatka back-arc to Miocene (3–6 Ma) and Late Pleistocene to Holocene (<1 Ma) times. Trace elements and isotopic compositions show that ... -
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 ... -
Magma chamber evolution prior to the Campanian Ignimbrite and Neapolitan Yellow Tuff eruptions (Campi Flegrei, Italy)

Magmatic Activity and Dynamics of Melt Supply of Volcanic Centers of Ultraslow Spreading Ridges: Hints From Local Earthquake Tomography at the Knipovich Ridge
; ; (Geochemistry, Geophysics, Geosystems, 2022-10-07)
Along ultraslow spreading ridges melt is distributed unequally, but melt focusing guides melt away from amagmatic segments toward volcanic centers. An interplay of tectonism and magmatism is thought to control melt ascent, ... -
Magmatic and Sedimentary Structure beneath the Klyuchevskoy Volcanic Group, Kamchatka, From Ambient Noise Tomography
; ; ; ; ; ; Luehr, Birger; ; Abkadyrov, Ilyas; Droznin, Dima; Gordeev, Evgeny (Journal of Geophysical Research: Solid Earth, 2020-03-14)
The Klyuchevskoy Volcanic Group is a cluster of the world's most active subduction volcanoes, situated on the Kamchatka Peninsula, Russia. The volcanoes lie in an unusual off‐arc position within the Central Kamchatka ... -
Magmatic and volcanological evolution of the Desertas rift zone (Madeira Archipelago, NE Atlantic)

Magnetic coupling of the solar photosphere and chromosphere
(Univ. Freiburg (Breisgau), 2008)The solar surface outside sunspots and active regions, i.e., the quiet Sun, shows the ubiquitous pattern of granulation in the photosphere. The quiet solar photosphere harbors small-scale magnetic structures inside and ... -
