Variability of the surface water partial pressure of CO2 in the North Sea.

The article discusses a study on the difference of the partial pressure of carbon dioxide (pCO₂) in the North Sea. It provides an overview of previous studies on the quantification of the ocean carbon cycle. The materials and methodologies used in the study are outlined. It also includes information on a calculation scheme used to identify and quantify factors that control the variability of pCO₂.
