Professor Robert Upstill-Goddard
Professor of Marine Biogeochemistry


My early research was in the role of sediment–water exchange in estuarine chemistry and the estuarine reactivity of the rare earth elements (REEs) but I subsequently developed an interest in climatically active trace-gas cycling and air–sea exchange. I was part of a small team at The Marine Biological Association of the UK (later Plymouth Marine Laboratory) and the University of East Anglia that developed the so-called ‘dual-tracer technique’ for estimating gas transfer velocities at sea using sulphur hexafluoride and helium-3, a method now regarded as the ‘gold standard’ for measuring air–sea gas exchange rates on short timescales. My current work includes evaluating the environmental controls of air–sea gas transfer, especially the role of surfactants and the microbiology of the sea-surface microlayer, and the biogeochemical cycling and air–sea exchange of methane and nitrous oxide in estuaries and mangroves, on coastal shelves, and in the open ocean. I also maintain an interest in the role of terrestrial dissolved organic matter in marine trace gas and ‘available nitrogen’ photo-production. I have served on a number of UK and EU Committees, contributed to the European Nitrogen Assessment and the CARBOEUROPE report on greenhouse gas emissions from the European Coastal Zone, and I co-edited proceedings of the International Symposium on Greenhouse Gas and Carbon Balances in Mangrove Coastal Ecosystems, 2005.

Research Interests

I lead the Ocean Research group. Our research is currently supported by NERC and The Leverhulme Trust and with the aid of this funding we are addressing the following questions:

How important are marine systems, especially coastal systems, to the global cycles of climatically active trace gases such as carbon dioxide, nitrous oxide, methane, and volatile sulphur?

What factors control the air-sea gas exchange process and can we parameterise them in a robust way?

What roles do bacteria at the sea surface (the Bacterioneuston) play in air-sea trace gas exchange?

What is the role played by surfactants in air-sea trace gas exchange, and can these surfactants be identified and quantified?

How reactive is Chromophoric Dissolved Organic Matter (CDOM) in coastal waters and what are the implications of this reactivity for global biogeochemical cycles?

To help try to answer these questions we have a number of ongoing research projects:
