ASGAMAGE

ASGAMAGE Air Sea GAs Marine Aerosol and Gas Exchange (ASGAMAGE) was an EU MAST-3 project with ship time contributed by the NERC ACSOE project as part of its MAGE component. The objectives of ASGAMAGE were: To find relationships between the transport coefficients for the gas fluxes and any relevant geophysical parameters. To test new methods and new equipment for the measurement of air-sea fluxes of CO2, DMS and other gases. To intercompare different methods and systems to measure the transfer velocity of trace gases over the sea. To find out whether and, if at all, under what conditions there can be a significant vertical gradients in the carbon dioxide concentration in the upper metres of the water column The field experiments were carried out in May and October 1996 at and around the Meetpost Noordwijk research platform (9 km off the Dutch coast). During the second period the UK research vessel RRS Challenger operated in the vicinity of the platform. The instrument platform was heavily instrumented collecting oceanographic, atmospheric and meteorological parameters thus: The instruments on the west boom were concerned with the measurement of gas transfer velocities using the eddy correlation technique. The Challenger cruise was primarily concerned with the field measurement of air-sea gas transfer velocities using double (SF6/3He) and triple(SF6/3He/bacterial spores) tracers and the collection of basic oceanographic and meteorological data.
