There are three important reasons for measuring pCO2 continuously from coastal moorings. The first is to evaluate whether coastal oceans are functioning as a source or a sink of atmospheric CO2. The open ocean and more distal parts of the shelves are reasonably well characterized as either typical CO2 sinks or sources (Takahashi et al., 2009), while the inner shelves are most variable and (with a general predominance of a source function) least well constrained; coastal areas are expected to be rather vulnerable to climate change in the 21st century. This of course has direct consequence of managing CO2 as a pollutant. Near continuous measurements of pCO2 will provide some understanding of the fluxes, their variability and their forcing parameters. The second reason involves the changes in saturation state of the water with respect to carbonate minerals and the impact on calcifying ecosystems. Surface pCO2 measurements in conjunction with direct measureme.....
