Ms Chloe Walker-Trivett
Areas of research:
I am embedded within the Deep time global change research group at the University of Exeter and jointly funded by the NERC GW4+ DTP and BGS. For my current PhD research, I am examining oceanographic and biotic changes in Australia during Oceanic Anoxic Event 2 (Cretaceous – Cenomanian/Turonian boundary) by:
- Reconstructing changes in sea surface temperature before, during and after OAE 2 using GDGTs and the TEX86 proxy – looking for overall warming during the period, as well as possible short term cooling events.
- Examining local oceanic productivity throughout the Cretaceous (with a special focus on OAE 2) using dinoflagellate cist assemblages, considering both oceanic upwelling and nutrient delivery from terrestrial sources.
- Processing pollen grains and spores to reconstruct terrestrial vegetation changes in the region during OAE 2, and subsequently, changes in the hydrological cycle at this time.
