I, Amelia Davies, work on carbonate clumped isotope thermometry. Our project specifically focuses on using the novel dual (∆47 -∆48)  carbonate clumped isotope technique to reconstruct paleotemperature and palaeolatitudinal temperature gradients across periods of contrasting atmospheric pCO2. Dual carbonate clumped isotope thermometry allows us to identify and potentially correct for kinetically mediated disequilibrium in clumped isotopic composition facilitating more robust paleotemperature reconstruction across a wide range of fossil carbonates.
