Der Ausstieg aus der Atomenergie und die Energiebilanz Deutschlands

Reinhard F. Huettl & Franz Ossing
Germany’s political decision to refrain from the further use of nuclear energy by the year 2022 has far reaching implications for this highly industrialized nation. Not only the production of electricity but the whole energy supply system is subject to this most ambitious reorganization of Germany’s energy structure. Industry as well as private households, i.e. production as well as consumption behaviour will have to face a profound change. In their report to the Chancellor of...

Eingeschlossene Ressource. Methan in natuerlichen Gashydraten

Judith Maria Schicks, Manja Luzi & Erik Spangenberg
The presence of natural gas hydrates at all active and passive continental margins has been proven. Their global occurrence as well as the fact that huge amounts of methane and other lighter hydrocarbons are stored as natural gas hydrates has led to the idea of using hydrate bearing sediments as an energy resource. However, natural gas hydrates remain stable as long as they are in mechanical, thermal and chemical equilibrium with their environment. Thus, for...

Quick-look gravity field analysis of formation scenarios selection

Optimized Gravity Field Determination from Future Satellite Missions

B. Elsaka & J. Kusche
Various concepts for future satellite-gravimetric missions are investigated within the German joint research project »Concepts for future gravity field satellite missions«, funded by the German Geotechnologies program »Observation of the Earth system from space« ofthe German Federal Ministry of Education and Research (BMBF). One of the project goals is todefine and assess different scenarios of satellite formation flight (SFF) configurations byimplementing full-scale simulations. To this end, we create simulated measurements for these satellite configurations, compute...

Geothermisch angetriebene Dampfkraftprozesse : Analyse und Prozessvergleich binärer Kraftwerke

Silke Köhler
Die tiefe Geothermie in Deutschland erschließt Reservoirs in 3 bis 5 km Tiefe mitTemperaturen von 100 °C bis 200°C. Für die Wandlung dieser Niedertemperaturwärme in elektrische Energie kommen voraussichtlich nur Kraftwerke mit Sekundärkreislauf in Frage.Die zwei zur Zeit verfügbaren Systeme, der Organic Rankine Cycle (ORC) und der Kalina-Prozess werden analysiert und bewertet. Die aus den Wasserdampfprozessen bekannten Methoden zur Verbesserung des Wirkungsgrades werden hinsichtlich ihrer Übertragbarkeit geprüft, alternative Möglichkeiten der Verbesserung untersucht und daraus praktikable...

Deformation, erosion and natural resources in continental collision zones : insight from scaled sandbox simulations

Silvan Hoth
Bivergent wedges result from the interaction between deformation, flexure and surface processes. Based on 2D sandbox simulations in conjunction with PIV, this study investigates the influence of these processes on the spatio-temporal evolution of strain-partitioning within, and the associated surface uplift of, bivergent wedges. To facilitate interpretation and to successfully communicate results, two new display types, i.e., the surface uplift and the evolution of deformation map are introduced.

Manteldynamik, magmatische Prozesse und das Aufbrechen der Kontinente

Robert B. Trumbull, Jakob K. Keiding, Ilya Veksler & Rolf L. Romer
The separation of Africa and South America about 130 million years ago was accompanied by huge volumes of magma derived from the mantle. Erosion has removed many of the surficial lavas but dolerite dyke swarms beneath them are preserved. These dykes are under study to determine the composition of magmas, the age of magmatism, and the direction of extensional stress in the crust. Here, we compare two dolerite dyke swarms from the southern African margin...

Seismische Datengewinnung – moderne Messsysteme verbessern die Abbildung des tiefen Untergrunds

Christian Haberland & Trond Ryberg
Most of our knowledge of the Earth’s interior results from seismological observations. The measurements are based on the fact that different rock types show different physical properties, and that seismic waves (e.g., from earthquakes or explosions) travelling through the Earth can be observed at the surface and be used to infer the internal architecture. Early seismological observations revealed the layered structure of the Earth, and today scientists are working on imaging the regional and local...

Die tiefe Erde im Labor

Sergio Speziale, Hans J. Reichmann & Hauke Marquardt
Seismological and other geophysical observations from the surface show that the internal structure of our planet consists of concentric layers: the crust (on which we live), the mantle and a metallic core. However, even the deepest drill holes can access less than 1 percent of the Earth depth for chemical/physical measurements or sampling. A multidisciplinary approach combining geophysics, geochemistry, petrology and geodynamic modeling is required in order learn more about the deep Earth. Mineral physics...

Ultrahochdruck-Eklogite aus dem nordwestlichen Himalaya: eine Studie zu den Druck-Temperatur-Zeit-Bedingungen ihrer Exhumation

Franziska Wilke
Using petrology, isotope geochemistry and thermochronology, continental rocks were investigated that have been subducted and metamorphosed under ultra high-pressure (UHP) conditions. The metamorphic conditions during burial and exhumation of eclogites, schists and gneisses from the tectonically and climatically influenced north-western Himalaya, from the Kaghan Valley in Pakistan, were analysed, and ages and rates of exhumation determined. A multi-stage exhumation path is evident. It is shown that the UHP rocks initially experienced very rapid exhumation of...

Wie steht es um die Gletscher in Zentralasien? Ein Lagebericht auf der Grundlage satelliten- und bodengestuetzter Messungen

Daniel Farinotti, Andreas Güntner, Franz Barthelmes, Sergiy Vorogushyn & Doris Duethmann
Glaciers play an important role in the water cycle of many regions of the world, especially in dry regions such as Central Asia. Glaciers can store water over decades and transfer winter precipitation into the summer months by releasing the accumulated snow and ice as melt water. The question about the state of the glaciers within a region is therefore intrinsically linked to questions about water availability and food security. We assess the current state...
