DESCRIPTION:The two-way exchange of trace gases and particles from the oce
 an to the atmosphere can have profound impacts on the chemistry and physic
 s of the atmosphere. It emerged a decade or so ago that ocean-sourced atmo
 spheric halogen gases have a pervasive impact on tropospheric chemistry\, 
 and more recent work is establishing the role of surface iodine chemistry 
 in enhancing the deposition of surface ozone.  Sea salt aerosol produced f
 rom physical processes over the ocean surface can interact with gases to i
 mpact a range of atmospheric processes\, including the cycling of reactive
  nitrogen oxides.  This presentation will highlight the importance of air-
 sea exchanges for global atmospheric cycling and discusses the discovery o
 f novel chemistry at the surface of the ocean and on marine aerosol\, whic
 h helps us better understand these impacts.\n
