John Marshall is an oceanographer interested in climate and the general circulation of the atmosphere and oceans, which he studies through the development of mathematical and numerical models of key physical and biogeochemical processes. His research has focused on important, and usually difficult, problems of ocean circulation involving interactions between motions on different scales, using theory, laboratory experiments, observations and new innovative approaches to global ocean modeling pioneered by his group at MIT.Current research interests include: ocean convection and subduction, stirring and mixing in the ocean, eddy dynamics and the Antarctic Circumpolar Current, the role of the ocean in climate, climate dynamics, aquaplanets. He is Director of MIT's Climate Modeling Initiative.
