资源简介:
This data supports the findings in the manuscript titled "Predicting pH at in-situ temperature for aquatic environments". Experiments were performed to analyze how the pH of seawater changes with changing temperature conditions (∆pH/∆T) across a range of salinities. Data was collected by measuring pH spectrophotometrically with simultaneous temperature measurements via a mini surface temperature probe. The total alkalinity (AT) of the seawater sample and salinity were measured for each sample to fully define the marine CO2 system. ∆pH/∆T was determined for a pH (at 25°C) range of 7.2–8.2, a temperature range of 15–40°C and salinities 10.1, 20.2, 30.2, and 36.1.
