Climate Change and Earth-Ocean-Atmosphere Systems
Katherine Daniels’ research looks at the processes of injection and transportation of geological fluids within the crust. The mechanism of magma transport through cold lithosphere and crust, and the distance over which it travels, controls the presence and type of resultant surface volcanism as well as the rate of spreading of the crust. At depths close to the Earth’s surface, magma is transported in dykes by the fracturing of the surrounding rock; an efficient method of transporting hot material through a cold environment.
Katherine works on applying numerical modelling techniques to study dyke injection processes beneath rifted margins or active volcanoes, and benchmarks her models using field observations and laboratory analogue models. Katherine can often be found in the laboratory, injecting fluids such as water or oil into solids like gelatine or glycerin to replicate and learn about natural geological processes.
Aside from volcanology, Katherine is also interested in the migration of CO2 within oil reservoirs, and in understanding the contribution of CO2-dissolution into the surrounding formation brines, on the reactions with the reservoir rocks and the resultant changes in porosity and permeability.
