Definition
- The North Atlantic Experiment was a pert 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 investigate the mechanisms producing climatically important gases in seawater. To investigate how the rates of climatically important gas production vary with biological and physiochemical parameters. To assess whether measured gaseous emissions can be used in models to identify the major atmospheric transformation processes. To investigate how the plankton community responds to atmospheric deposition of nutrients in terms of growth rates and production of climaticallyThe experiment was based around an RRS Discovery cruise in June and early July 1998 that followed the development of a bloom in a patch of water marked with SF6. Associated aircraft overflights to investigate the physical and chemical evolution of particles in the marine boundary layer were planned but were not possible. A wide range of oceanographic, meteorological and atmospheric parameters were measured during the cruise. 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. important trace gases and their precursors.
