Andrew James Watson FRS (born 1952) is a British marine and atmospheric scientist and an expert in processes affecting atmospheric carbon dioxide and oxygen concentrations. He was formerly a Professor of biogeochemistry in the School of Environmental Sciences at the University of East Anglia, in 2013 he moved to a position as Professor at the College of Life and Environmental Sciences at the University of Exeter.
Earth sciences
Watson graduated with a first class BSc in physics from
Anthropic Principle to evolution on Earth,[3]
suggesting that long-term regulation of the Earth’s temperature and environment may be a necessary pre-requisite to allow sufficient time for the evolution of complex life and intelligence, rather than an intrinsic property of the biosphere as Lovelock proposed.
Tracing ocean waters
While at the
sulphur hexafluoride and perfluorodecalin.[4] He and colleagues applied these to measure the slow mixing vertical rates in the ocean,[5] and to trace the movement of patches of surface water.[6] He also applied the technology to enable iron fertilization experiments.[7] More than a dozen such experiments have now been carried out[8]
and have proved that iron is an essential limiting nutrient in important areas of the world ocean.
Popular science
Watson published the popular book Revolutions that Made the EarthPhilomena Cunk.[10]
