Different from the solution/physical pump, biological pump and continental shelf pump of carbon cycle in oceans, a new pump named “surface microlayer (SML) pump” is developed based on data obtained from marine investigations and lab study. The SML pump has: (1) left-right dissymmetry of “pH-depth” curve; (2) the non-linearity of “concentration-depth” curve; and (3) difference of affect-ing confine of the SML pump. The issue of “source” or “sink” of atmospheric CO2 in the Yellow Sea and South China Sea is discussed. 展开更多
