Alkalinity addition ranged from 500 to 2000 micromoles per kilogram (µmol.kg-1) and the carbonate chemistry was monitored through time by measuring total alkalinity (TA) and dissolved inorganic carbon (DIC), which were used to calculate Ω. The amount of precipitate and its minerology were determined throughout the experiments. Mineral precipitation took place in all experiments over a timescale of hours to days. The dominant mineralogy of precipitate is aragonite with trace amounts of calcite and brucite. Aragonite crystallite size increases and its micro-strain decreases with time, consistent with Ostwald ripening. This dataset contains carbonate chemistry data that include TA and DIC measurements, precipitation rates from the shipboard experiments, and precipitation rates calculated in the same way (by changes in alkalinity through time) for the study of Moras et al. (2022) and precipitation rate data from Mucci et al. (1989).\n\ncdm_data_type = Other\nVARIABLES:\nExperiment_name (unitless)\nTA_addition (micromoles (umol))\nStart_day (unitless)\nStart_time (unitless)\nEnd_day (unitless)\nEnd_time (unitless)\nDuration (hours (h))\nmeasured_TA (micromoles per kilogram (umol/kg))\nTA_std (micromoles per kilogram (umol/kg))\nmeasured_DIC (micromoles per kilogram (umol/kg))\nDIC_std (micromoles per kilogram (umol/kg))\ncalculated_DIC (micromoles per kilogram (umol/kg))\ncalculated_CaCO3_precipitate (milligrams per kilogram (mg/kg))\n | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_963736_v1/index.htmlTable | https://osprey.bco-dmo.org/dataset/963736
