Dead Sea Pollen Reveal the Paleoenvironment of the Southern Levant during 147–89 ka from the Paleobotanical Perspective
(2017-12-06)
This study analyzes pollen, non-pollen-palynomorphs, and charcoal from the deep-drilled Dead Sea 5017-1A sediment cores. It reconstructs a high-resolution vegetation and environment history of the southern Levant at 147–89 ...
On the probabilistic evaluation of decadal and paleoclimate model predictions
(2017-11-27)
The development of climate prediction systems for years to decades is an area of current research, as these time scales are important e.g. for the planning horizon of decision-makers. Those prediction systems can be improved ...
Fluid driven processes in the crust – the formation of anorthositic dykes in the Troodos ophiolite (Cyprus)
(2017-10-12)
Anorthositic dykes related with the Upper Cretaceous Troodos ophiolite are described for the first time. An entire anorthosite dyke swarm appears within the Limassol Forest Complex, crosscutting the supply channels of late ...
Abbildende Spektroskopie erosionsrelevanter Bodenparameter in Agrarökosystemen
(2013-01-23)
Die Vielzahl der Funktionen, die der Boden in einem Ökosystem übernimmt, verleiht ihm einen hohen Stellenwert im Mensch-Umwelt-System. Der Boden landwirtschaftlicher Nutzflächen ist im Besonderen eine elementare Säule der ...
Entwicklung eines automatisierten Wolkendetektions- und Wolkenklassifizierungsverfahrens mit Hilfe von Support Vector Machines angewendet auf METEOSAT-SEVIRI-Daten für den Raum Deutschland
(2013-03-20)
Wolken stellen im Klimasystem der Erde einen zentralen Faktor dar, nicht nur in Bezug auf die Niederschlagsverteilung, sondern auch in Verbindung mit Effekten auf Strahlungsvorgänge innerhalb der Atmosphäre. Eine genaue ...
Modeling hydrological processes in a semi-arid mountainous catchment at the regional scale
(2013-04-02)
In the Upper Drâa Valley (14,988 km2) on the southern slopes of the Moroccan High Atlas Mountains, a highly variable precipitation and large evaporation losses cause major water availability problems. The combined ...
Statistical Quality Assurance and Peer Review in Primary Data Publication
(2013-01-23)
Publication of results is an elementary part of scientific work. Started in in 17th century with the traditional scientific publications several new forms emerged in recent years, triggered by the digital ...
Modeling the spatio-temporal evolution of fracture networks and fluid-rock interactions in GPU: Applications to lithospheric geodynamics
(2013-04-16)
In this thesis, I present the theory and modeling of poro-elasto-plastic rheology coupled to a non-linear diffusion equation with a step increase in permeability at the onset of slip. This theoretical model is implemented ...
Atmospheric Downscaling using Multi-Objective Genetic Programming
(2017-10-10)
Numerical models are used to simulate and to understand the interplay of physical processes in the atmosphere, and to generate weather predictions and climate projections. However, due to the high computational cost of ...
Generating high resolution precipitation conditional on rainfall observations and satellite data
(2017-09-15)
This study is part of the high resolution reanalysis project proposed for Germany and Europe (Bollmeyer et. al., 2014) within the framework of the Hans Ertel Centre for Weather Research (HErZ). The reanalysis for Germany ...
