Global and regional climate are profoundly influenced by patterns of ocean circulation, which in turn is modulated by the distribution of continents and seafloor topography. Motions of the continents over millions of years shift and reshape the ocean basins, causing ocean currents to change. Dramatic changes can occur when continents break apart opening ‘seaways’ that control seawater flow between major ocean basins.
Grabenbrüche bieten ein einzigartiges Fenster in das geodynamische System unseres Planeten und die Prozesse, welche die Erdoberfläche formen. Das Projekt CRYSTALS trägt zu grundlegendem Verständnis der kontinentalen Riftdynamik und der Entstehung passive Kontinentalränder bei. In unseren Modellierungen verwenden neueste numerische Methoden und folgen einem multi-skaligen Modelldesign.
Many fundamental evolutionary cycles on Earth - including the dispersal of supercontinents and the global carbon cycle - are driven by our planet's dynamic engine, plate tectonics. Geodynamic processes hold important implications for climate science since CO2 is released from Earth’s interior into the atmosphere. In order to link plate tectonics and complex lithospheric deformation to the global carbon cycle we combine plate tectonic reconstruction with numerical carbon cycle simulation. This allows quantifying the tectonic evolution of plate boundaries as well as tectonic CO2 release rates through deep time with profound implications for long-term climate simulations.
RHUM-RUM (Réunion Hotspot and Upper Mantle - Réunions Unterer Mantel) is a French-German passive seismic experiment designed to image a classical oceanic mantle plume – or lack of plume – from crust to core beneath Réunion Island. The results enable insights into the material and heat flow in the Earth's deep interior and provide a geodynamic context for the still controversially debated deep mantle plumes.
Since the Great Sumatra 2004 Boxing Day earthquake and tsunami GFZ provides research and methodologic development in the fields of tsunami hazard assessment and early warning. Section 2.5 Geodynamic Modeling supports these activities with numerical modeling of tsunami generation, propagation and coastal impact within both deterministic and probabilistic frameworks. Our Section also participates in the development of the innovative GNSS-based technology for tsunami early warning.
