ASGAMAGE is an acronym that is the contraction of ASGAS–EX (for Air Sea Gas Exchange project) and MAGE.

The ASGAMAGE project started on March 1, 1996 and lasted until March 1, 1999. The scientific objectives were to:

  • Find relationships between the transport coefficients for the gas fluxes and any relevant geophysical parameters;
  • Test new methods and new equipment for the measurement of air–sea fluxes of CO2, DMS and other gases;
  • Intercompare different methods and systems to measure the transfer velocity of trace gases over the sea; and
  • Find out whether and, if at all, under what conditions there can be a significant vertical gradient in the CO2 concentration in the upper meters of the water column.

ASGAMAGE consisted of two experimental periods, with the first taking place from May 6 to June 7, 1996. It involved taking measurements at and around the Meetpost Noordwijk (MPN), a research platform 9 km off the Dutch coast. The second period, taking place from Oct. 7 to Nov. 8, 1996, involved more measurements at MPN and a cruise of the RRS Challenger. The measurement activities were primarily aimed at a determination of air–sea gas transfer coefficients with the differential tracer method being made simultaneously with micrometeorological experiments.
