Earth's magnetic field

by

Project Summary
The magnetic field measured by satellites has 3 distinct sources: the dynamo in the liquid core, magnetised rocks near the Earth’s surface, and the external, solar terrestrial environment. It is difficult to separate out the large-scale field (originates in the earth’s core) from the small-scale, permanent field (originates in the earth’s crust). This project aims to develop physical theories for the origin of each field to aid separation, accompanied by comparison with satellite data and iterative improvements. It is envisaged that this project will extend our knowledge of the core field to unprecedented fine resolution while establishing the larger scales of the crustal field.  … Read more…

The global fracture zone and magnetic lineation data base project

by

Project Summary
Plate kinematic models derive from the detailed identifications of conjugate magnetic isochron picks and fracture zones (FZ). These data form the foundation of all relative marine plate tectonic reconstructions and codify our understanding of Earth’s surface evolution since the Mesozoic. Furthermore, FZ traces have extensive uses in many other marine geophysical investigations such as studying the origins of transform fault offsets, identifying seamounts and isolating abyssal hill roughness within fracture zone provinces, examining predictions from competing thermal models of the lithosphere, and much more. Kinematic models also require temporal information and this dimension is provided by identification of key magnetic isochron boundaries from total field magnetic anomalies collected along ship tracks. … Read more…

Planet scale reorganisations of the plate-mantle system

by

Project Summary
Global climate change and shrinking resources have heightened our sense of dependence on the earth as a dynamic and complex system. This project aims to provide a unifying context for enhancing our understanding and appreciation of the workings of the inner earth and, in particular, its complex system behaviour during major tectonic events. … Read more…
