Despite of the many processes that affect gas exchange at the air-sea interface, up to now wind velocity is typically the only factor that is used to estimate gas transfer velocity. On the other hand, it is so hard to directly measure the gas transfer at the air-sea interface. Because of this difficulty, large uncertainties still remain on gas transfer velocity. Using molecular dynamics simulation, the seawater property and the motions of CO2, O2, N2, Ar, and Kr in the diffusive layer beneath the air-sea interface are investigated. Then, their diffusion coefficients at different temperatures are calculated. The detail of CO2 behaviors is discussed as well. The molecular dynamics simulation will be a new theoretical tool for calculating the gas transfer velocity in the future.
