Gavin Foster

I am a Lecturer in Ocean and Earth Science at the University of Southampton. My research is principally concerned with using novel isotopic techniques to gain insights into how and why the Earth’s climate has changed over geological timescales. Much of my research efforts are currently focused on using boron isotopes in the calcareous shells of foraminifera to reconstruct the state of the oceanic carbonate system in the geological past. In particular I am interested in the mechanisms responsible for the CO2 changes that accompanied the waxing and waning of the ice-sheets throughout the Pleistocene, and the role of CO2 in the gradual (and sometimes rapid) deterioration of climate through the Cenozoic.

I am the Principal Investigator of the Descent into the Icehouse project and I’m responsible for the overall co-ordination and management of the project. My main research role is to aid Eleni Anagnostou (PDRA at Soton) to measure the boron isotopic composition of foraminifera from Tanzania (and other deep ocean sites) in my boron-laboratory at the University of Southampton.
