[1] Iodine containing species have been measured in the
particle phase (PM2.5) and the gas phase during a ship
campaign between January and February 2007 in the South
Atlantic marine boundary layer (MBL). Methyl iodide
(CH3I) in the gas phase and soluble iodine species, i.e.
iodide, iodate and an unidentified organic iodine species
(UOI), in PM2.5 were measured. Temporal variations of
gaseous and particulate iodine species were investigated.
The exposure of the sampled air masses to phytoplankton
along the backtrajectories was studied using a lagrangian
transport model and satellite observations of oceanic
