Untersuchungen zur Geschwindigkeitsstruktur im unteren Erdmantel und im Bereich der Kern-Mantei-Grenze unterhalb des Pazifiks mit Scherwellen
(Institut für Meteorologie und Geophysik, Johann Wolfgang Goethe-Universität Frankfurt am Main, 1990)
In der vorliegenden Arbeit werden anomale Laufzeitdifferenzen zwischen den Mantel- und Kernphasen S, Sdiff, SKS und SKKS mit lateralen Geschwindigkeitsperturbationen gegenüber dem Standarderdmodell PREM erklärt. Das ...
Structure and evolution of the northern part of the Northeast German Basin revealed from seismic interpretation and 3D structural modelling
(Univ. Hamburg, 2007)
During several marine geophysical data acquisition cruises in the western Baltic Sea, for the Baltseis and NeoBaltic projects, a dense grid of 2D high-resolution multichannel seismics and to some extend gravity and magnetic ...
Surface properties of asteroids from mid-infrared observations and thermophysical modeling
(Univ. Berlin, 2007)
The subject of this work is the physical characterization of asteroids, with an emphasis on the thermal inertia of near-Earth asteroids (NEAs). Thermal inertia governs the Yarkovsky effect, a non-gravitational force which ...
Doppler radar monitoring of lava dome processes at Merapi Volcano, Indonesia
(Univ. Hamburg, 2007)
Merapi volcano in Central Java, Indonesia, is considered one of the most dangerous volcanoes worldwide. Due to the high viscosity of its magma, the lava emerging at the top the volcano cannot flow silently down the flanks ...
Microfabrics of ultra-high pressure metamorphic rocks in the Dora Maira Massif, Western Alps
(Univ. Bochum, 2007)
Ziel der Arbeit ist sowohl eine Lokalisierung der rezent aktiven seismogenen Zonen in diesem Gebiet sowie eine Deutung dieser Seismizität und ihrer Charakteristik im Kontext der regionalen Seismotektonik. Die seismische ...
The H_1n+3 + H2 isotopic system
(Univ. Köln, 2008)
Dense cold molecular clouds reckoned to be stellar nurseries are the scene of an extreme molecular deuteration. Despite the cosmic D/H ratio of 10^{-5}, molecular species in prestellar cores are observed to contain nearly ...
Retrieval of surface emissivity of sea ice and temperature profiles over sea ice from passive microwave radiometers
(Univ. Bremen, 2007)
Sea ice, surface emissivity, emitting layer temperature, temperature profile, microwave radiometry. - Polar regions play a key role in the global climate. The information on atmospheric parameters in these regions is sparse. ...
Low-temperature thermochronology
(Univ. Freiberg, 2008)
Die Spaltspuren-Datierung als wesentliche Methode aus dem Bereich der Niedrigtemperatur-Thermochronologie basiert auf der Zählung und Messung geätzter Spuren unter dem Mikroskop. Für eine akkurate Altersbestimmung ist daher ...
Crustal structure modelling and interpretation of the East Greenland continental margin between 72°N and 77°N
(Univ. Bremen, 2008)
Integrated studies of conjugate margins provide important constraints for the sequence of events of synrift tectonic and magmatic processes. The northeast Greenland margin is investigated based on seismic refraction data ...
Experimental constraints on silicate perovskite forming reactions and elastic properties
(Univ. Bayreuth, 2008)
