초록
This study investigates the generation and movement of low-concentration CO2observed in Gosan during summer from 2002 to 2006. For analysis, additional CO2 data in Anmyeondo, Ryori, Barrow, and Minamitorishima as well as NOAA/ESRL daily global CO2fields, background trajectories data, and 850 hPa wind fields are also used. Based on analyses using various observed data, we classified three types of low-concentration CO2 in Gosan according to its origin: i) the origin of the Siberian continental, in which the consumption of CO2is active due to photosynthesis from broad forests, ii) the origin of Okhotsh and Artic seas, in which the low-concentration CO2 is dominant due to high primary productivity by a plankton bloom, and iii) the origin of the Northwestern Pacific which is related to the entry of air mass from high latitudes. These results show that the low-concentration CO2 observed in Gosan during summer is not originated from the Pacific oceans as known in previous studies, but originated from high latitude regions such as the Siberian continental and the Okhotsh and Artic seas.
