These data are collected and analyzed to assess spatial and temporal variation in the seawater carbonate systems of coral reef ecosystems and include two types of sampling methods. The first method is collected by hand or niskin at the surface, either from the boat or by SCUBA divers. The second method uses subsurface autosamplers where water samples provided in this dataset were collected at a depth of approximately 15m. Samples are either collected singularly or as part of a diurnal set. The samples are processed by the Atlantic Oceanographic Meteorological Laboratory (AOML) where they are analyzed for total alkalinity (TA), dissolved inorganic carbon (DIC) and Spectrophotometric pH. Using the analyzed TA and DIC, alongside temperature, salinity and depth data, AOML staff calculated other important carbonate chemistry system parameters such as pH, pCO2, and aragonite saturation and reported the results in this dataset. Provide high-quality carbonate chemistry data (dissolved inorganic carbonand total alkalinity) for US coral reef areas at a several spatial and temporal scales, in close partnership with the larger CRCP NCRMP and OAP/PMEL NOA-ON efforts.

NOAA National Centers for Environmental Information custodian carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
