Abstract

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...

This table is a summary table of the pH internal consistency experiment, averaging raw values from related datasets.

Measured total alkalinity and measured DIC are averages from the related dataset "pH internal Consistency Experiment: TA & DIC".

The measured pHt are average pHt for each temperature. Values were extrapolated to zero indicator added as described in Woosley 2021 and Woosley and Moon 2023. Raw measurements can be found in the related datatset "pH internal Consistency Experiment: Raw pH Data".
