Assessing the effect of marine isoprene and ship emissions on ozone, using modelling and measurements from the South Atlantic Ocean
Ship-borne measurements have been made in air over the remote South Atlantic and Southern Oceans in January-March 2007. This cruise encountered a large-scale natural phytoplankton bloom emitting reactive hydrocarbons (e. g. isoprene); and a high seas squid fishing fleet emitting NOx (NO and NO2). Us...

Ship-borne measurements have been made in air over the remote South Atlantic and Southern Oceans in January-March 2007. This cruise encountered a large-scale natural phytoplankton bloom emitting reactive hydrocarbons (e. g. isoprene); and a high seas squid fishing fleet emitting NOx (NO and NO2). Using an atmospheric chemistry box model constrained by in-situ measurements, it is shown that enhanced ozone production ensues from such juxtaposed marine biogenic and anthropogenic emissions. The relative impact of shipping and phytoplankton emissions on ozone was examined on a global scale using the EMAC model. Ozone in the marine boundary layer was found to be over ten times more sensitive to NOx emissions from ships, than to marine isoprene in the region south of 45 degrees. Although marine isoprene emissions make little impact on the global ozone budget, co-located ship and phytoplankton emissions may explain the increasing ozone reported for the 40-60 degrees S southern Atlantic region. |
