Mittelquartäre Klimaverhältnisse und Reliefentwicklung im semiariden Becken von Vera (Südostspanien)
(E&G – Quaternary Science Journal; Vol.42, No. 1)Im nördlichen Teil des Beckens von Vera treten als älteste quartäre Formen villafrancazeitliche beckenrandnahe Schwemmfächer und Glacisakkumulationen auf, die an der Basis Travertine enthalten, deren ESR-Altersabschätzung ... -
Mittelsteinzeitliche Fundplätze im Spree-Dahme-Winkel (Ein Beitrag zur Kenntnis des Brandenburgischen Mesolithikums)
(E&G – Quaternary Science Journal; Vol.09, No. 1)Langjährige Geländebegehungen in der Nordwest-Ecke des Kreises Beeskow-Storkow haben in dieser urgeschichtlich bisher nur wenig erschlossenen Gegend zahlreiche mesolithische Fundplätze ergeben. Die Hauptmasse des durch die ... -
Mittlere Gebirgsdurchlässigkeiten der hydrogeologischen Einheiten im Großraum Grünstadt, Rheinland-Pfalz
(Mainzer geowissenschaftliche Mitteilungen; 41. 2013)
Veränderungen der Grundwasserverhältnisse im Großraum Grünstadt sind der Auslöser für aktuelle hydrogeologische Untersuchungen der oberen Wasserbehörde. in diesem zusammenhang wurden auf der Basis von Altdaten aus dem ... -
Mixed Layer Depth Promotes Trophic Amplification on a Seasonal Scale
; ; ; ; ; ; (Geophysical Research Letters, 2022-06-16)
The Humboldt Upwelling System is of global interest due to its importance to fisheries, though the origin of its high productivity remains elusive. In regional physical‐biogeochemical model simulations, the seasonal amplitude ... -
Mobile Lebensformgruppen Südost-Arabiens im Wandel - Die Küstenprovinz Al Bāţinah im erdölfördernden Sultanat Oman
(Selbstverlag des Geographischen Instituts der Freien Universität Berlin, 1981)Die von SCHULZ (1976; 1979; 1980) für den Wandel in den kleinen Staaten des Golfs entworfene übergreifende These kann für diese Studie als Arbeitshypothese dahingehend formuliert werden, dass (1) auch eine begrenzte ... -
Mobilisation of Arsenic in the low-flow regime of groundwaters in Bangladesh
(Freiberg Online Geosciences; Vol. 20.2009) -
Model building and imaging with reflection data
(Univ. Hamburg, 2002)The purpose of the first part of this dissertation was to develop a migration algorithm for converted waves, and a tomographic method for estimating an interval shear wave velocity model. The developed algorithm is based ... -
Model simulation of seasonal growth of Fucus vesiculosus in its benthic community
; ; ; ; (Limnology and Oceanography: Methods, 2020)
Numerical models are a suitable tool to quantify impacts of predicted climate change on complex ecosystems but are rarely used to study effects on benthic macroalgal communities. Fucus vesiculosus L. is a habitat-forming ... -
Modeling and inversion in weakly anisotropic media
(Univ. Hamburg, 2004)Mit der Annahme schwacher Anisotropie vereinfachen sich die Lösungen der Modellierung und Inversion anisotroper Medien. Üblicherweise werden Perturbation-Methoden zur Beschreibung der Wellen-Ausbreitung in schwach anisotropen ... -
MODELING AND SIMULATION OF IRON/SAND FILTERS
Kamga, Fulbert Togue;; Woafo, Paul (Revue des sciences de l'eau, 2012)
This article develops a mathematical model of Iron (Fe0) /sand filter taking into account the loss of porosity during the filtration process. The mass transport advection-dispersion equation is derived to predict, through ... -
Modeling atmospheres of classical novae in X-rays with PHOENIX
(Univ. Hamburg, 2005)PHOENIX has been used to calculate model atmospheres of classical novae in the X-ray spectral range. The models account for an expanding, one-dimensional spherically symmetric medium in full non-local thermodynamic ... -
Modeling cloud properties over the 79 N Glacier (Nioghalvfjerdsfjorden, NE Greenland) for an intense summer melt period in 2019
; ; (Quarterly Journal of the Royal Meteorological Society, 2022-11-04)
Long believed to be insignificant, melt activity on the Northeast Greenland Ice Stream (NEGIS) has increased in recent years. Summertime Arctic clouds have the potential to strongly affect surface melt processes by regulating ... -
Modeling Fluid Reinjection Into an Enhanced Geothermal System
; (Geophysical Research Letters, 2020)
Abstract The manuscript analyzes the stimulation for an Enhanced Geothermal System development in Acoculco, Mexico. Using an analytical penny-shaped hydraulic fracture model covering different propagation regimes, we ... -
Modeling light curves of type Ia supernovae
(Univ. Hamburg, 2009)The main topic of this work is the introduction of time dependence into PHOENIX. This has been achieved for both the radiation field and the matter in the SN Ia model atmosphere. First, time dependence in the radiative ... -
Modeling Lithospheric Thickness Along the Conjugate South Atlantic Passive Margins Implies Asymmetric Rift Initiation
; ; ; ; ; (Tectonics, 2022-09-20)
The lithospheric architecture of passive margins is crucial for understanding the tectonic processes that caused the breakup of Gondwana. We highlight the evolution of the South Atlantic passive margins by a simple thermal ... -
Modeling Net Ecosystem Exchange for Grassland in Central Kazakhstan by Combining Remote Sensing and Field Data
(Remote Sensing, 2009)Carbon sequestration was estimated in a semi-arid grassland region in Central Kazakhstan using an approach that integrates remote sensing, field measurements and meteorological data. Carbon fluxes for each pixel of 1 × ... -
Modeling ocean-induced rapid Earth rotation variations: an update
; ; ; (Journal of Geodesy, 2021-09-07)
We revisit the problem of modeling the ocean’s contribution to rapid, non-tidal Earth rotation variations at periods of 2–120 days. Estimates of oceanic angular momentum (OAM, 2007–2011) are drawn from a suite of established ... -
Modeling of methane migration from gas wellbores into shallow groundwater at basin scale
; ; (Environmental Earth Sciences, 2020-09-18)
Methane contamination of drinking water resources is one of the major concerns associated with unconventional gas development. This study assesses the potential contamination of shallow groundwater via methane migration ... -
