The Marine and Atmospheric Sciences Group is distinctive in its breadth: arguably what sets it apart from other groups in the UK is its encompassing of physical, chemical and biological oceanography along with the physics and chemistry of the atmosphere. This broad portfolio has enabled world-leading research both within each discipline and also across disciplines and at the fluid interface. For example a long-running strength has been atmosphere-ocean interactions (both physical and chemical) and coupled atmosphere-ocean processes. Our research focuses on both global and regional topics in marine and atmospheric chemistry, as well as in global and regional (e.g. polar and maritime continent) oceanography and meteorology.
