(Selbstverlag Fachbereich Geowissenschaften, FU Berlin, 1994)In der vorliegenden Arbeit werden Untersuchungen zur Verteilung des elektrischen Widerstandes in den südlichen zentralen Anden vorgestellt. Gestützt auf eine breite Datenbasis konnten mit Hilfe von ein- und überwiegend ... -
Modelling and interpretation of global lithospheric magnetic anomalies
(GFZ, Helmholtz-Zentrum, 2003)After a gap of nearly two decades since the Magsat mission in 1980, the dedicated low-orbit potential field mission CHAMP is now in the third of its seven year mission. Already, the new magnetic total intensity and vector ... -
Modelling and parametrization of the convective flow over leads in sea ice and comparison with airborne observations
(Quarterly Journal of the Royal Meteorological Society, 2021-02-07)A non‐eddy‐resolving microscale model is applied to simulate convection over three different leads (elongated channels in sea ice), which were observed by aircraft over the Arctic Marginal Ice Zone in 2013. The study aims ... -
Modelling cometary meteoroid stream traverses of the Martian Moons eXploration (MMX) spacecraft en route to Phobos
(Earth, Planets and Space, 2021-04-16)The Martian Moons Exploration (MMX) spacecraft is a JAXA mission to Mars and its moons Phobos and Deimos. MMX will be equipped with the Circum-Martian Dust Monitor (CMDM) which is a newly developed light-weight (650g) large ... -
Modelling forest lines and forest distribution patterns with remote sensing data in a mountainous region of semi-arid Central Asia
(Biogeosciences Discussions, 2014)Satellite images and digital elevation models provide an excellent database to analyze forest distribution patterns and forest limits in the mountain regions of semiarid central Asia on the regional scale. For the ... -
Modelling future lahars controlled by different volcanic eruption scenarios at Cotopaxi (Ecuador) calibrated with the massively destructive 1877 lahar
(Earth Surface Processes and Landforms, 2021-02-05)Lahars are among the most hazardous mass flow processes on earth and have caused up to 23 000 casualties in single events in the recent past. The Cotopaxi volcano, 60 km southeast of Quito, has a well‐documented history ... -
Modelling groundwater salinisation in irrigated coastal areas - from solute recycling concepts to quantitative risk assessment
(Univ. Neuchâtel, 2005)The main objective of this thesis is the quantitative investigation of groundwater salinisation induced by solute recycling from irrigation, and its implications for the overall salinisation in coastal settings. Since the ... -
Modelling of sediment supply from torrent catchments in the Western Alps using the sediment contributing area (SCA) approach
(Earth Surface Processes and Landforms, 2021-02-08)The production of coarse sediment in mountain landscapes depends mainly on the type and activity of geomorphic processes and topographic and natural conditions (e.g. vegetation cover) of these catchments. The supply of ... -
Modelling of surface waves in poroelastic saturated materials by means of a two component continuum - lecture notes ; CISM course: surface waves in geomechanics, Undine, September 2004
(WIAS, Berlin2004)These lecture notes are devoted to an overview of the modelling and the numerical analysis of surface waves in two-component saturated poroelastic media. This is an extension to the part of the lecture notes by K. Wilmanski ... -
Modelling the Earth's magnetic field of magnetospheric origin from CHAMP data
(Scientific Technical Report / Geoforschungszentrum Potsdam; 2004, 06)As observed on the Earth's surface, the magnetic field can be separated into three components: The "Main Field", the "Crustal Field"; and the "External Magnetic Field". This work concentrates on the magnetospheric current ... -
Modelling the marine carbonate pump and its implications on the atmospheric CO2 concentration
(Univ. Bremen, 2001)The marine carbonate pump includes the production of calcium carbonate, CaCO3 by marine organisms and its subsequent transport to depth. The balance between carbonate production in surface waters and dissolution and ... -
