The Centre for Ocean and Atmospheric Sciences at UEA combines a unique selection of scientists studying the physics and chemistry of the atmosphere as well as the physics, chemistry and biology of the oceans and the important links between the atmosphere and oceans.  We have close links with the Climatic Research Unit (CRU) and the Tyndall centre at UEA as well. COAS is funded by the Natural Environment research Council, The Leverhulme Trust, The Royal Society, the European Research Council and several other funders including international funders such as the US National Science Foundation, the German Deutsche Forschungsgemeinschaft and Bundesministerium fuer Bildung und Forschung.

The following list contains examples of the areas covered by our recent and ongoing work, more details can be found in the profiles of the individual members of COAS.
