Concentrations of atmospheric and oceanic CO2 in the Southern Ocean

Concentrations of atmospheric and oceanic CO2 concentration were continuously measured in the Southern Ocean during the cruise of Umitaka-Maru in 2009. The samples for Dissoloved Inorganic Carbon (DIC) were also collected at surface during cruise as well as respective layers in observation area and these are carried out in lab for measuring by coulometer. http://biows.nipr.ac.jp/~plankton/um0809-1a.png
