Preliminary result of observation in the Antarctic Sea using pCO2 autonomous buoy
The total ocean uptake flux including the anthropogenic CO2 was estimated to be 2.0±1.0Pg-C/yr in a reference year 2000 by Takahashi et al.(2009). However, contribution of the seaonal ice-freezone in the southern ocean was about 0.06 Pg-C/yr. This estimate flux was smaller than that estimeted previo...
