The fluxes of green house gases such as CoィイD12ィエD1 at the air-sea interface and the gas exchange mechanism were studied by means of the following 5 methods. They are geochemical balances analysis of at mospheric concentrations, concentration differences at the air-sea interface, temporal changes in the water column inventories and changes recorded in the marine sediments. The most important result obtained is the effect of bubbles. The bubbles not only enhance the gas transfer velocities but also make it extremely large for soluble gases. This enhancement is due to the dissolution of by the hydrostatic pressure.

用以下5种方法研究了绿色温室气体如Co γ D12 γ D1在海-气界面上的通量及其气体交换机理。它们是大气层浓度的地球化学平衡分析、海气界面浓度差异、水柱清单的时间变化和海洋沉积物记录的变化。得到的最重要的结果是气泡的影响。气泡不仅提高了气体传输速度，而且使其对于可溶性气体而言非常大。这种增强是由于静水压力的溶解。
