Radiocarbon Science Leader, GNS Science

Presentation Title: Dramatic lockdown fossil fuel carbon dioxide decrease detected by citizen science supported radiocarbon observations

Jocelyn Turnbull holds joint appointments at GNS Science, New Zealand the University of Colorado, USA. Dr Turnbull started her career as a radiocarbon technician and lab manager, and then obtained her PhD on Development and Environmental Applications of Atmospheric 14CO2 Measurement from the University of Colorado at Boulder in 2006. She spent time establishing a global radiocarbon modelling capability at the Laboratoire des Sciences du Climat et de l’Environnement, before moving to the NOAA Global Monitoring Laboratory in Boulder, USA, where she was primarily involved in establishing urban greenhouse gas observational methodologies. In 2011, she returned home to New Zealand where she leads the GNS Science Rafter Radiocarbon Laboratory, which maintains expertise in a wide range of radiocarbon applications, supporting earth science research in New Zealand and around the world. Jocelyn’s research investigates the modern carbon cycle, particularly the source and fate of fossil fuel derived CO2, She uses radiocarbon and related tracers to understand the sources and sinks of greenhouse gases at the local, urban and regional scales. Current projects include: CarbonWatch-NZ evaluating New Zealand’s natural and anthropogenic carbon budget; INFLUX, the Indianapolis Flux Project evaluating urban greenhouse gas emissions; and SOAR, Southern Ocean Atmospheric Radiocarbon, investigating Southern Ocean carbon exchange. She is co-chair of the World Meteorological Organisation’s IG3IS initiative, connecting atmospheric greenhouse gas observations to local, national and international climate policy.
