ACSOE-EAE

The Eastern Atlantic Experiment was a part of the Marine Aerosol and Gas Exchange (MAGE) component of the Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) project. The aims of the experiment were: To quantify input of DMS into a parcel of air To examine the oxidation of DMS and its reaction with nitrogen species with time To investigate the formation of new particles as a result of these transformations To discriminate between the natural and anthropogenic fractions of sulphur and nitrogen using isotopic measurements The experiment included two campaigns in the spring seasons of 1996 and 1997, each of which incorporated three elements: A land-based site at Mace Head (at the seaward end of Galway Bay) A research vessel operating off the west coast of Ireland (RRS Challenger) Research aircraft overflights to link shipborne and land-based measurements The primary measurements made during the campaigns were concentrations of DMS in the atmosphere and the water column, but a wide range of additional measurements were made including: Atmospheric ozone and nitrogen species Atmospheric particulates and their chemistry Atmospheric nitrogen and sulphur isotopic composition Oceanic temperature, salinity, attenuance and chlorophyll Meteorology The fieldwork was supported by modelling work with a zero-dimensional time-dependent photochemical box model of an air mass in the marine boundary layer.
