Temperature, salinity, and pH measurements were conducted every other day throughout the experimental period. Temperature was measured using a high precision partial-immersion glass thermometer (precision \u00b10.3%; accuracy \u00b10.4%). Salinity (\u00b1SD) was measured using a YSI 3200 conductivity meter and maintained at 31.7 (\u00b10.2), with slight natural seasonal variation as expected in Massachusetts Bay waters. A\u00a0pH probe calibrated with 7.00 and 10.01 NBS buffers kept at experimental temperatures was used to measure pH in each tank. Water samples were taken from each tank every ten days around 13:00 Eastern Time using 250 mL ground-glass-stoppered borosilicate glass bottles for analysis of total alkalinity (TA) and dissolved inorganic carbon (DIC). TA and DIC were measured via coulometry and closed-cell potentiometric Gran titration, respectively calibrated with certified Dickson DIC/TA standards. Dissolved CO2 ([CO2 (SW)]), carbonate ion concentration [CO32\u2013], bicarbonate ion concentration [HCO3\u2013], pCO2, aragonite saturation state, and pH of the seawater from all treatments were calculated from measured temperature, salinity, DIC, and TA using CO2SYS (Pierrot et al, 2006) with Roy et al. (1993) carbonic acid constants K1 and K2 and NBS (mol kg\u20131 H2O) pH scale.

This water chemistry data set includes water temperature, salinity, and pH of all 24 experimental aquaria measured every other day throughout the 93-day ocean acidification and warming experiment. Additionally, the data include the measured (temperature, salinity, total alkalinity, and dissolved inorganic carbon) and calculated (Dissolved CO2, carbonate ion concentration, bicarbonate ion concentration], pCO2, aragonite saturation state, and pH) carbonate parameters from water samples taken every 10 days during the experiment. These data were used to determine the experimental conditions of each treatment that the corals were exposed to.\u00a0These data are presented in Bove et al (2019).
