Alkalinity addition ranged from 500 to 2000 micromoles per kilogram (µmol/kg) 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 raw XRD data as well as XRD results (mineral abundances, crystallite size, strain, and unit cell parameters) determined via Rietveld refinement. The seawater for the experiments was collected near the Bermuda Atlantic Time Series (31.6667 N, 64.1667 W), which is also the same location where the experiments were conducted and filtered to obtain the precipitates, which were analyzed with XRD.\n\ncdm_data_type = Other\nVARIABLES:\nExperiment_name (unitless)\nAlkalinity_addition (micromoles per kilogram (umol/kg))\nSample (unitless)\nExp_start_day (unitless)\nExp_start_time (unitless)\nFiltration_start_day (unitless)\nFiltration_time (unitless)\nFiltration_end_day (unitless)\nFiltration_end_time (unitless)\nDuration_till_filtration_started (hours)\nDuration_till_filtration_ended (hours)\nExperiment_mean_duration (hours)\nFiltration_duration (hours)\nAragonite (percent)\n...
