Multilayer Study Of Carbon Dioxide System In The Surface Waters Of The Yellow Sea, South China Sea And Qingdao Coast

The ocean is a very important connection in global carbon cycles, which plays a leading role in carbon exchange and transfer between the lithosphere, seabed sediment, biosphere and atmosphere. Nowadays, the study on the transfer and end-result of carbon dioxide including the ocean's ability in absorbing and transferring the atmospheric carbon dioxide, the cycle mechanism of carbon dioxide in oceans et al. has been an important content in many international marine scientific research plans, such as JGOFS, LOICZ and IGBP, especially in the Surface Ocean and Lower Atmosphere Study (SOLAS).The sea surface microlayer (SML) is a thin layer situated between the sea and atmosphere, which is the inevitable way of material exchange in the sea-air interface. Because of its unique physical, chemical and biological properties, the SML have an important and direct effect on biogeochemical cycles in ocean, material fluxes in sea-air interface and global climates. But systematical multilayer studies on carbon dioxide system of the"SML - SSL - SL"in the surface waters are scarcely reported by now. In this article the SML is introduced to the carbon dioxide cycle in sea-air interface of the marginal sea in China for the first time. In addition, the key study is put upon the carbon dioxide system including DIC, Alk, pH and pCO2 in SML, SSL, SL of the sea surface waters to look for the principal regularity of carbon cycle in the sea-air interface and the role of SML. On the basis of the experimental results obtained from the sea research, a new model of global carbon cycle is hoped to set up finally.This work includes: (1) The SML is introduced to the carbon dioxide cycle in sea-air interface of the marginal sea in China for the first time. In addition,...
