Project Title: Understanding small-scale heterogeneities through Earth's mantle and crust

Supervisors: Dr S Rost, and Professor G Stuart

Funding: NERC CASE

Start date: October 2010

Project Outline

The general structure of the Earth is already known from seismic studies which average global properties. Smaller, localised structures generate low amplitude signals in seismic records so are more difficult to separate from background noise and hence are not well constrained. Using collections of seismometers or arrays to enhance weak seismic signals I intend to locate small-scale structures which deviate from the global average model of the Earth and determine their relations to larger-scale features. Knowledge of these local structures and their interaction with regional features will help to increase our understanding of mantle dynamics and chemistry.

My present focus is on heterogeneities at the Core-Mantle Boundary, the interface separating the liquid iron core from the overlying solid, silicate mantle. The chemical, thermal, and mechanical contrasts in this region may have significant impact on the mantle convection and Earth's magnetic field.
