According to our analysis of the air occluded in sea ice which was collected in the Antarctic region, 0.1 to 0.5 ml/kg (at NTP) of carbon dioxide was contained. On the other hand, TORII et al (1959) showed that the partial pressure of carbon dioxide in sea water in the Antarctic region often reaches as high as 6×10-4atm. p. Contribution of carbon dioxide which escapes in summer months from sea ice and sea water in the Antarctic was estimated. Results of calculation showed that though the increase in the concentration of carbon dioxide in the air due to the escape of carbon dioxide is small, the total amount of release is 1.8×1013g/y and 1.2×1014g/y respectively for sea ice and sea water. These amounts are comparable to the rate of production from other sources whose importance in the geochemical cycle of carbon dioxide in the atmosphere has been well established.
