©2020 Biological and Chemical Oceanography Data Management Office.These data include the measured pHt, total alkalinity, dissolved inorganic carbon, raw pHt absorbance, and calculated pHt of 25 batches of seawater as a function of temperature, salinity, and pCO2. These data were used to evaluate the internal consistency of 120 different possible combinations of CO2 system constants. The marine inorganic carbon system can be calculated with two measured parameters due to thermodynamic relationships. However, there are many different parameterizations for th...
Show moreOligotrophic Atlantic surface seawater was collected from 39° 46.406′ N and 70° 53.065′ W on October 10, 2019.
The surface seawater was modified to five different salinities and 5 different pCO2 values for a total of 25 batches. Salinity was modified through dilution or evaporation. pCO2 was modified by bubbling CO2 gas of different pCO2 concentrations (balance air).
The water was then bottled and sealed into 250 mL borosilicate glass bottles following SOPs (Dickson et al. 2007). Each batch consisted of 44 bottles.
