The focus of this theme is on understanding the fundamental physical and chemical processes that govern interaction between the deep Earth, surface and atmosphere.
In order to unravel the complexities of these interactions we exploit the rich geological record of past events and use direct and remote sensing observations of modern processes and a wide range of modelling.
The feedbacks and forcings which couple the deep Earth to Earth’s surface include mantle circulation and melting, and volcanoes and tectonics which mediate the interface between the solid Earth and the biosphere/ hydrosphere/ atmosphere.
(i) Deep Earth Dynamics examines how the processes deep in the Earth have created our current surface environment. Deep Earth processes and plate tectonics underpin the global earthquake cycle and mantle circulation leads to large‐scale changes in Earth’s surface topography. Influences also extend to long-term changes in carbon dioxide in the atmosphere.
(ii) Surface Geodynamics involves the study of the interacting physical, chemical, and biotic processes that operate at or near the surface of the Earth. It considers how both deep and surface processes impacts the physical chemical and biological mass transfers on land and under the sea.
