Keywords:

  • air–sea gas, partial pressure representing gaseous mixture composition;
  • dissolved gases in seawater, and importance;
  • gas solubility in seawater, factors controlling its uptake by oceans;
  • air–sea interface concentration difference, gradient and diffusive flux;
  • modeling gas transfer adequately, for transfer velocities to be determined;
  • SFM in oceanography, adequate first-order of complex processes;
  • stagnant boundary layer model, gas transferred by molecular diffusion;
  • oceans as a source for gases to atmosphere, and as sink for others;
  • direct measurement of air–sea gas exchange, generally difficult;
  • CFM or CFCs, net atmosphere to ocean transfer, as deep water tracers
