Abstract
- This paper aims to provide an overview of regional carbon fluxes and budgets in the marginal seas adjacent to China. The “China Seas” includes primarily the South China Sea, East China Sea, Yellow Sea, and the Bohai Sea. Emphasis is given to CO<subscript>2</subscript> fluxes across the air-sea interface and their controls. The net flux of CO<subscript>2</subscript> degassing from the China Seas is estimated to be 9.5±53 Tg C yr<superscript>−1</superscript>. The total riverine carbon flux through estuaries to the China Seas is estimated as 59.6±6.4 Tg C yr<superscript>−1</superscript>. Chinese estuaries annually emit 0.74±0.02 Tg C as CO<subscript>2</subscript> to the atmosphere. Additionally, there is a very large net carbon influx from the Western Pacific to the China Seas, amounting to ∼2.5 Pg C yr<superscript>−1</superscript>. As a first-order estimate, the total export flux of particulate organic carbon from the upper ocean of the China Seas is 240±80 Tg C yr<superscript>−1</superscript>. This review also attempts to examine current knowledge gaps to promote a better understanding of the carbon cycle in this important region. [ABSTRACT FROM AUTHOR]
