Novel methodological approaches in loess research – interrogating biomarkers and compound-specific stable isotopes
Zech, Michael;
; Buggle, Björn; (E&G – Quaternary Science Journal; Vol.60, No. 1)
Löss-Paläoboden Sequenzen sind wichtige terrestrische Archive für die Rekonstruktion der quartären Landschafts- und Klimageschichte. Die Entwicklung neuer, quantitativerer Paläoklima-Proxies könnte in den kommenden Jahren ... -
Novel Quantification of Shallow Sediment Compaction by GPS Interferometric Reflectometry and Implications for Flood Susceptibility
; ; ; (Geophysical Research Letters, 2020)
Estimates of flood susceptibility and land loss in the world's coastal regions depend on our knowledge of sea level rise (SLR) from increases in ocean mass and volume, as well as knowledge of vertical land motion. Conventional ... -
Nowcasting and Predicting the Kp Index Using Historical Values and Real-Time Observations
; ; (Space Weather, 2019)
Current algorithms for the real-time prediction of the Kp index use a combination of models empirically driven by solar wind measurements at the L1 Lagrange point and historical values of the index. In this study, we explore ... -
NPP-ID: Non-Pollen Palynomorph Image Database as a research and educational platform
; ; ; (Vegetation History and Archaeobotany, 2021-08-30)
Non-pollen palynomorphs (NPPs) form a large group of biological objects found in palynological slides besides pollen grains. This includes various remains of algae and fungi, shells, resting stages and eggs of invertebrates, ... -
Number of Chamber Measurement Locations for Accurate Quantification of Landscape‐Scale Greenhouse Gas Fluxes: Importance of Land Use, Seasonality, and Greenhouse Gas Type
; ; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-09-23)
Accurate quantification of landscape soil greenhouse gas (GHG) exchange from chamber measurements is challenging due to the high spatial‐temporal variability of fluxes, which results in large uncertainties in upscaled ... -
Numerical analysis of gravity and magnetic fields prior to structural modelling
; (2021)
The work presented here is part of ongoing studies in the AlpArray initiative and the priority program "MB-4D" regarding the modelling of the lithosphere in the Ligurian Sea (northwestern Mediterranean Sea). It will be ... -
Numerical analysis of the interaction between rockbolts and rock mass for coal mine drifts in Vietnam
(Univ. Freiberg (Sachsen), 2008)Since decades rockbolts are widely used as a support measure in mining and civil engineering. The presented literature review under special consideration of the situation in underground Vietnamese coal mines has revealed ... -
Numerical analysis of transport in dynamical systems
(Univ. Paderborn, 2005)Transport processes play an important role in many natural phenomena. Prominent examples are the chaotic advection of fluid particles in geophysical flows or the transport of asteroids and comets in the solar system. Similar ... -
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
; ; Lauritzen, Peter H. (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 ... -

; ; ; ; ; ; ; ; ; (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 ...
