Atmospheric Carbon Dioxide Content as Syowa Station
During the 13th Japanese Antarctic Research Expedition in 1972-1973 the determination of the carbon dioxide content of the surface air was carried out at Syowa Station (69°S, 39.5°E) in Antarctica, by using Infra-Red Gas Analyzer. The station is located on East Ongul Island, 5km off the Antarctic Co...
