Geophysics, Geodynamics and Tectonics
I am a geophysicist studying the link between phenomena we can observe at the surface, such as faulting and volcanism, and large scale convective processes which take place deep within Earth's interior.
I use seismic reflection imaging, along with other geophysical methods, to unravel the connections between mantle convection, plate spreading, and surficial ups and downs in the oceans and fringing continental margins. I am also interested in the formation of oceanic crust where plate spreading is accommodated along low-angle detachment faults, which may play a major role in the formation of oceanic basins.
Prior to my PhD I spent four years in the hydrocarbon industry, where I worked on various exploration and development projects in North Africa, Trinidad & Tobago and the UK Continental Shelf.
Above: Seismic reflection profile, ~1200 km in length, spanning the entire North Atlantic Ocean from Greenland margin in the west (left) to European margin in the east (right). Mid-oceanic spreading axis at centre. V-shaped ridges of thickened crust imaged beneath sediments. These V-shaped ridges contain a continuous record of mantle plume activity over the past 50 million years. Red line = filtered satellite gravity anomaly. From Parnell-Turner et al.
