| Research Abstract |
In the global warming, carbon dioxide(CO2) plays an important role and its transport through air-sea interface should be quantitatively evaluated. We have developed on-board eddy-covariance system including energy and trace gas fluxes. Air-sea CO2 flux is leas than an order of magnitude smaller than vegetation over land and should be evaluated very accurately. Eddy-covariance measurement of DMS flux is also tried as well as successful vertical profile method.
