Dr Savannah Worne

Stable isotope research assistant
BGS Keyworth

Savannah is a Stable Isotope Research Assistant within the BGS Geochemistry department, focusing on preparing and analysing a range of samples for organic carbon and nitrogen isotopes (using the new Elementar precision mass spectrometer). Prior to joining BGS, Savannah was a PhD student at the University of Nottingham, where her thesis research centred on creating a high resolution reconstruction of sea ice, nutrient cycling and ocean-atmosphere CO2 dynamics in the Bering Sea over the last one million years, using geochemical and micropalaeontological records from a deep-ocean sediment core taken by the Integrated Ocean Drilling Program (IODP).
