Distribution of dissolved inorganic carbon (DIC) in the Chukchi Sea of the Arctic Ocean in summer 2010

At each hydrographic station, 244 samples for dissolved inorganic carbon (DIC) were taken from Niskin bottle to 500 ml boro-silicate glass bottles on board. Accurate measurement concerning spatio-temporal variability in CO2 in the water column is highly important to understanding of global carbon cycle and reliable prediction for the future atmospheric concentration of CO2.

From flux study perspective of CO2, the Arctic Ocean has known as sink for atmospheric CO2. But there wasn't enough data, and sea ice have an ambiguous role of air-sea CO2 exchange so that further research must be conducted.
