Title: Measured and calculated water chemistry parameters throughout a 93-day acidification and warming experiment from 2015-06-01 to 2015-12-30 (NCEI Accession 0291980)
Abstract: This dataset contains chemical and physical data collected from 2015-06-01 to 2015-12-30. These data include Aragonite Saturation State, Carbonate concentration [CO3]2-, bicarbonate concentration [HCO3]-, dissolved inorganic Carbon, pCO2, pH, salinity calculated from CTD primary sensors, total Carbon Dioxide in seawater, total alkalinity, and water temperature. The instruments used to collect these data include CO2 Coulometer, Conductivity Meter, MARIANDA VINDTA 3C total inorganic carbon and titration alkalinity analyser, Thermometer, and pH Sensor. These data were collected by Karl D. Castillo of University of North Carolina at Chapel Hill as part of the "Investigating the influence of thermal history on coral growth response to recent and predicted end-of-century ocean warming across a cascade of ecological scales (Thermal History and Coral Growth)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-12-09.

The following is the text of the dataset description provided by BCO-DMO:

Dataset Description:
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.

Supplementary information: Acquisition Description:
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 ±0.3%; accuracy ±0.4%). Salinity (±SD) was measured using a YSI 3200 conductivity meter and maintained at 31.7 (±0.2), with slight natural seasonal variation as expected in Massachusetts Bay waters. A pH 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–], bicarbonate ion concentration [HCO3–], 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–1 H2O) pH scale.

CO2SYS v2.1 was used to calculate carbonate parameters. http://cdiac.ess-dive.lbl.gov/ftp/co2sys/
