英文摘要	Marine carbonate system monitoring programs often consist of multiple observational methods that include underway cruise data, moored autonomous time series, and discrete water bottle samples. Monitored parameters include all, or some of the following: partial pressure of CO2 of the water (pCO(2w)) and air, dissolved inorganic carbon (DIC), total alkalinity (TA), and pH. Any combination of at least two of the aforementioned parameters can be used to calculate,the others. In this study at the Gray's Reef (GR) mooring in the South Atlantic Bight (SAB) we: examine the internal consistency of pCO(2), from underway cruise, moored autonomous time series, and calculated from bottle samples (DIC-TA pairing); describe the seasonal to interannual pCO(2w) time series variability and air-sea flux (FCO2), as well as describe the potential sources of pCO(2w) variability; and determine the source/sink for atmospheric pCO(2). Over the-8.5 years of GR mooring time series, mooring-underway and mooring-bottle calculated pCO2w strongly correlate with r-values > 0.90. pCO(2w) and FCO2 time series follow seasonal thermal patterns; however, seasonal non-thermal processes, such as terrestrial export, net biological production, and air-sea exchange also influence variability. The linear slope of time series pCO(2w) increases by 5.2 +/- 1.4 atm y(-1) with FCO2 increasing 51-70 mmol m(-2) y(-1). The net FCO2 sign can switch interannually with the magnitude varying greatly. Non-thermal pCO(2w) is also increasing over the time series, likely indicating that terrestrial export and net biological processes drive the long term pCO(2w) increase.
