Numerical determination of pressure‐dependent effective thermal conductivity in Berea sandstone
(Geophysical Prospecting, 2021-11-12)In this paper, the methods of digital rock physics are applied to determine pressure‐dependent effective thermal conductivity in rock samples. Simulations are performed with an in‐house three‐dimensional finite volume code. ... -
Numerical impacts on tracer transport: A proposed intercomparison test of Atmospheric General Circulation Models
(Quarterly Journal of the Royal Meteorological Society, 2020-09-07)The transport of trace gases by the atmospheric circulation plays an important role in the climate system and its response to external forcing. Transport presents a challenge for Atmospheric General Circulation Models ... -
Numerical investigation of the turbulent ISM
(Univ. Bochum, 2007)In this work we introduced basic turbulence theory into the framework of the interstellar medium. In many cases turbulence simulations are applied to the interstellar medium (ISM) merely because it is a medium, where ... -
Numerical Modeling of Structurally Controlled Ore Formation in Magmatic‐Hydrothermal Systems
(Geochemistry, Geophysics, Geosystems, 2022-08-11)Faults and fractures can be permeable pathways for focused fluid flow in structurally controlled ore‐forming hydrothermal systems. However, quantifying their role in fluid flow on the scale of several kilometers with ... -
Numerical simulation of magma ascent by dykes and crust formation at spreading centres
(Univ. Hamburg, 2005)Mittelozeanische Rücken finden sich in allen größeren Ozeanbecken der Erde. Sie besitzen die weltweit höchste Produktionsrate an Extrusiv- und Intrusivgesteinen. Bildung ozeanischer Kruste und Vulkanismus an divergenten ... -
Numerical simulations of neutron star - black hole mergers
(Univ. Potsdam, 2006)Collisions of black holes and neutron stars, named mixed binaries in the following, are interesting because of at least two reasons. Firstly, it is expected that they emit a large amount of energy as gravitational waves, ... -
Numerical Study of the Exchange Flow of the Persian Gulf Using an Extended Total Exchange Flow Analysis Framework
(Journal of Geophysical Research: Oceans, 2020)The Total Exchange Flow analysis framework computes consistent bulk values quantifying the estuarine exchange flow using salinity coordinates since salinity is the main contributor to density in estuaries and the salinity ... -
Numerically stable form factor of any polygon and polyhedron
(Journal of Applied Crystallography, 2021-03-25)Coordinate‐free expressions for the form factors of arbitrary polygons and polyhedra are derived using the divergence theorem and Stokes's theorem. Apparent singularities, all removable, are discussed in detail. Cancellation ... -
Numerische Simulationen des Ausbreitungsverhaltens von Wärmeträgerfluid-Inhaltsstoffen aus Erdwärmesonden in Trinkwassereinzugsgebieten
(Grundwasser, 2020-06-19)Aufgrund deutlich erhöhter Wärmebedarfsdichten urbaner Räume besteht in besonderem Maße hier die Möglichkeit und Erfordernis, durch eine nachhaltige Wärmeversorgung und saisonale Wärmespeicherung im geologischen Untergrund ... -
Nutrient and Silicon Isotope Dynamics in the Laptev Sea and Implications for Nutrient Availability in the Transpolar Drift
(Global Biogeochemical Cycles, 2022-09-23)Realistic prediction of the near‐future response of Arctic Ocean primary productivity to ongoing warming and sea ice loss requires a mechanistic understanding of the processes controlling nutrient bioavailability. To ... -
Nutrient co‐limitation in the subtropical Northwest Pacific
(Limnology and Oceanography Letters, 2021-08-17)Nutrients limiting phytoplankton growth in the ocean are a critical control on ocean productivity and can underpin predicted responses to climate change. The extensive western subtropical North Pacific is assumed to be ... -
Nutrient regulation of late spring phytoplankton blooms in the midlatitude North Atlantic
(Limnology and Oceanography, 2019)The duration and magnitude of the North Atlantic spring bloom impacts both higher trophic levels and oceanic carbon sequestration. Nutrient exhaustion offers a general explanation for bloom termination, but detail on which ... -
Nutzungsgeschichte, Zustand und Revitalisierung der Moore im Erzgebirge
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 32; 2002)Abstract: According to historical geological maps, the bogs on the German side of the Erzgebirge occupied approx. 6000 hectares at the end of the 19th century. Firstly, for the initial steps of a much needed, up-to-date ... -
Oberbodenabtrag: eine Methode zur großflächigen funktionellen Wiederherstellung von Niedermoorlebensräumen? – Ergebnisse einer Machbarkeitsstudie
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 45; 2015)Abstract: A pilot study was realized in 2013/2014 to investigate the restoration of degraded percolation mires by a large-scale top soil removal. Objectives and results of the study are presented. The project area is ... -
Oberer Rupelton, Schleichsand (Rupel) und Cyrenenmergel (tiefes Chatt) im Mainzer Becken - Können sie mikropaläontologisch definiert werden?
(Mainzer geowissenschaftliche Mitteilungen; 17. 1988)Die mikropaläontologische Bearbeitung einiger Bohrprofile im Mainzer Becken hat gezeigt, daß die Abfolge Oberer Rupelton-Schleichsand-Cyrenenmergel auf der Grundlage der bisherigen Annahmen nicht überall gliederbar ist. ... -
Oberflächenstruktur von Torf und Wasserbewegung auf der Oberfläche
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 48; 2018)Moorflächen sind auf den Kontinenten überall vorhanden. Aus Mooren lässt sich durch Entwässerung und Trocknung leicht der hochporöse Torfgewinnen. Torf ist ein natürliches und ungiftiges Rohmaterial, das wegen seiner ... -

Oblique Gravity Wave Propagation During Sudden Stratospheric Warmings
(Journal of Geophysical Research: Atmospheres, 2020)Gravity waves (GWs) are important for coupling the mesosphere to the lower atmosphere during sudden stratospheric warmings (SSWs). Here, a minor SSW is internally generated in a simulation with the upper-atmosphere ...
