Newsnight Statement
Research Interests
Global biogeochemical cycles, climate, and the interactions between them. In particular, processes influencing atmospheric carbon dioxide, (both natural variations in the past and the sinks for anthropogenic CO2) and atmospheric oxygen. Transport and ventilation of the modern and paleo-oceans.
Biography
For my early career, I studied the evolution of Earth's and other planets' atmospheres before moving to the marine laboratories at Plymouth and becoming more ocean-oriented. I worked there from 1981-1996 before moving to UEA. I developed tracer techniques that can be used to perform a new class of large-scale experiments in the ocean, and in collaborative experiments through the 1990s I used these techniques directly to observe the slow rates of mixing in the open ocean, and to show by release experiments that iron is a critical limiting nutrient for plankton. My group at UEA works on observations of the ocean carbon system and ocean physics using tracers, funded by EU and NERC grants. We also use a variety of models to investigate the processes affecting atmospheric carbon dioxide and oxygen concentrations through time. I was elected FRS in 2003 and awarded the EGU's Nansen Medal for "fundamental contributions to the understanding of the integrated oceanic system" in 2004.
