Gideon is a geochemist working to understand the ocean, the carbon cycle, and the long-term operation of the climate system.
His research falls into two main areas:
- making novel measurements on natural archives to quantify climate processes important for future change, such as:
- sea level
- rainfall patterns
- permafrost stability.
- the chemistry of the modern ocean, including study of:
- the carbon cycle
- nutrient metals
- tracers used to assess ocean processes.
Gideon helped initiate the international programme which has revolutionised knowledge of the chemical cycling of metals in the ocean, and was co-chair of this programme for its first decade.
He is a Professor at the Department of Earth Sciences (of which he was Head for 2013 to 2017) at the University of Oxford. He also holds a senior research fellowship at University College Oxford, and an associate position at Columbia University, USA.
Gideon was elected as a Fellow of the Royal Society in 2013, now serves on the Royal Society Science Policy Committee, and has contributed to recent policy work in subjects including ocean resources and greenhouse gas removal.
