Ten years of Spanish ion carbonate data in the North Atlantic Ocean and Mediterranean Sea

This dataset is composed of 2 files. The main one is the data set itself (10yy_CO3_Spanish_database_hy1.csv) in WHP-Exchange bottle format, with 2418 samples of temperature, salinity, silicate and phosphate concentrations, along with pH, alkalinity, total inorganic carbon and absorbance ratios for measuring ion carbonate in seawater with two different reagents [PbCl2 y Pb(ClO4)2]. Information about the cruise name, year and location (latitude and longitude) is also provided. Information about the spectrophotometric equipment use is also given. The other file (readme_ 10yy_CO3_Spanish_database.txt) includes a short description of the database variables, units and more details on the contained cruises.-- he data are provided under an Attribution-ShareAlike 4.0 International license.
