Processes Controlling the Carbonate Chemistry of Surface Seawater Along the 150°E Transect in the Northwest Pacific Ocean
文献摘要：
The problem of ocean acidification caused by the increase of atmospheric carbon dioxide concentration is becoming increasingly prominent. Field observation in the northwest Pacific Ocean was carried out along the 150°E transect in November 2019. The distribution characteristics and influencing factors of the surface seawater carbonate chemistry, including dissolved inorganic carbon (DIC), total alkalinity (TA), pH, partial pressure of carbon dioxide (pCO2) and aragonite saturation state (?arag) were investi-gated. DIC and TA ranged from 1915 to 2014 μmol kg?1 and 2243 to 2291 μmol kg?1, respectively; DIC in general decreased with decreasing latitude, but TA had no clear latitudinal gradient. pCO2 values increased with the decrease of latitude and were all below the atmospheric pCO2 level, ranging from 332 to 387 μatm. pH on the total hydrogen ion concentration scale (pHT) decreased with the decrease of latitude in the range of 8.044 – 8.110, while ?arag increased with the decrease of latitude in the range of 2.61 – 3.88, suggesting that the spatial distributions of pHT and ?arag were out of phase. Compared with the present, the predicted values of pHT and ?arag by the end of this century would decrease remarkedly; larger declines were found in the higher pHT and ?arag regions, re-sulting in the differences along the meridional gradient becoming smaller for both pHT and ?arag.
