An introduction to my PhD

My Research: "Carbon Cycling and Mass Extinctions"

My work involves trying to understand how the global carbon cycle responded and recovered from a major perturbation, namely the Permian-Triassic Mass Extinction. Occurring ~250 Ma and resulting in the loss of 90% of marine life the extinction event involved a large disruption of the carbon cycle. This is evidenced in the Carbon Isotope record for the Early Triassic which fails to return to 'normal' for around 5 Myrs after the extinction itself. The Early Triassic is characterised by major positive and negative carbon isotope excursions. My focus at the moment is to reconstruct redox changes across the Arabian Peninsula and trying to understand how these changes may impact carbon cycling.
