Chloe Walker-Trivett
Postgraduate Researcher
Geology
My PhD was embedded within the deep-time global change research group at the University of Exeter, jointly funded by the NERC GW4+ DTP and the British Geological Survey. My PhD research was in palaeoclimate reconstruction, looking specifically at Oceanic Anoxic Events (OAEs) in the mid-Cretaceous in marine sedimentary basins offshore SW Australia. I have now completed my doctorate (viva passed Dec. 2024), and recently started a PostDoc position at the Geological Survey of Denmark and Greenland (GEUS).
OAEs are associated with a major upheaval in the global carbon cycle, changes to ocean chemistry and oxygen availability, and associated increases in biotic turnover. To better understand both regional and global OAEs, I used stable isotope and radiogenic geochemistry, organic geochemistry, and micropalaeontological investigations to reconstruct carbon cycle perturbations, sediment provenance, sea surface temperature changes, biological responses and productivity changes.
