Abstract
We examined the spatial and temporal variability of partial pressure of CO2 (pCO2) in surface seawater in the western North Pacific and the East China Sea based on surface pCO2, temperature and salinity continuously measured on board R/V Onnuri in September 2006, October 2007, and June 2008, 2009 and 2010. The western North Pacific and the East China Sea were distinguished in not only sea surface temperature and salinity but also pCO2 distributions. The surface pCO2 showed higher values in the lower latitude (the western North Pacific) than those in the higher latitude (the East China Sea) in wide ranges. In the western North Pacific, the seasonal and interannual variations of surface pCO2 distributions were small, and vice versa. The western North Pacific acted as a weak or moderate source of CO2, of which fluxes ranging from 0.07 to 0.48 mmol m-2 day-1 at all times. However, the East China Sea acted as a sink of CO2 in both spring and summer. The fluxes ranged from -0.45 to -6.11 mmol m-2 day-1.V Onnuri in September 2006, October 2007, and June 2008, 2009 and 2010.
