Ocean station data with at least dissolved inorganic carbon (DIC) and total alkalinity (TA) measurements were obtained from the Global Ocean Data Analysis Project (GLODAP), the Carbon Dioxide in the Atlantic Ocean (CARINA), the Pacific Ocean Interior Carbon (PACIFICA), and some recent cruise data sets. Aragonite saturation state was calculated using a Matlab version of CO2SYS from in-situ temperature, pressure, salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), silicate and phosphate with the dissociation constants for carbonic acid of Lueker et al. [2000], potassium bisulfate (KHSO4-) of Dickson [1990a], boric acid of Dickson [1990b], and with the total borate concentration equations of Lee et al. [2010]. Aragonite saturation state was correct to January 1, 2000 before it was gridded to a world-wide grid with 1x1 degree latitude and longitude resolution. The Longitude values used in this dataset are from 20 to 380 degrees. For more information about the data set, please read the below paper: Jiang, L.-Q., R. A. Feely, B. R. Carter, D. J. Greeley, D.
