Dynamic Earth

cloudResearch in this area includes a range of work on the evolution of rifted margins with a current focus on an international collaborative project involving 3-D seismic profiling of the Iberian margin. The work has important implications for the role of deeply ingressing water, through serpentinization, in guiding the structural history of margins.

Research on spatial and temporal scales of mantle convection, supported by the Irish government, focuses on Cenozoic evolution of the north Atlantic. This links to global climate via both modulation of deep-water flow around Iceland and uplift-associated dissociation of gas hydrate. The development of techniques for detecting and quantifying gas hydrates and emissions of methane has been a key part of shallow geophysical investigations on continental slopes over the past two decades. This includes major participation in European programmes as well as NERC support.

Prize-winning research on igneous emplacement mechanisms integrates study of field relationships and magnetic fabrics, and has broadened to make novel uses of 3-D seismic information.
