The aim of my project is to evaluate the role of nutrient cycling and organic carbon production in driving intervals of widespread organic carbon burial. Several of such intervals in the Mesozoic have been associated with rapid globarming, perturbations to floral and faunal diversity and the expansion of low-oxygen marine environments and were responsible for the formation of a significant proportion of known marine hydrocarbon reserves. The combined use of isotope-based nutrient tracers (Cd, Zn) and established geochemical proxies has the potential to provide information on nutrient cycling and primary productivity rates of past oceans and will therefore be applied to a range of sites and intervals.
