SOLAS Seminar VI: Halogen chemistry: from ocean to stratosphere

 

Ocean biogeochemistry has long been recognised to impact the composition of the atmosphere, halogens being an excellent example. Recently, atmospheric halogen chemistry has received renewed attention for its role in climate cooling and ozone destruction. This SOLAS seminar will try to dress a "vertical" picture of halogens: from their biogeochemical cycling associated with dissolved organic matter in the oceans to modelling the connection between ocean and atmospheres (for iodine in particular) and their influence up to the lower stratosphere where they act as ozone depleting catalysts.
