Distributions and air-sea fluxes of CO2 in the summer Bering Sea
The 3rd Chinese National Arctic Research Expedition (CHINARE-Arctic Ⅲ) was carried out from July to September in 2008.The partial pressure of CO2 (pCO2) in the atmosphere and in surface seawater were determined in the Bering Sea during July 11-27,2008,and a large number of seawater samples were taken for total alkalinity (TA) and total dissolved inorganic carbon (DIC) analysis.The distributions of CO2 parameters in the Bering Sea and their controlling factors were discussed.The pCO2 values in surface seawater presented a drastic variation from 148 to 563 μatm (1 μatm=1.013 25×10-1 Pa ).The lowest pCO2 values were observed near the Bering Sea shelf break while the highest pCO2 existed at the western Bering Strait.The Bering Sea generally acts as a net sink for atmospheric CO2 in summer.The air-sea CO2 fluxes in the Bering Sea shelf,slope,and basin were estimated at-9.4,-16.3,and-5.1 mmol/(m2·d),respectively.The annual uptake ofCO2 was about 34 Tg C in the Bering Sea.
