The data from these MAPCO2 buoys complement a national array of moored carbon dioxide buoys across the Pacific, Atlantic, and Caribbean. The buoys are primarily funded by NOAA's Ocean Acidification Program and supported by NOAA's Pacific Marine Environmental Laboratory (PMEL), Atlantic Oceanographic and Meteorological Laboratory (AOML), and Coral Reef Conservation Program (CRCP). Samples are collected every two weeks from predetermined sites around the buoy from the boat or by SCUBA divers. The samples are processed by the AOML where they are analyzed for total alkalinity (TA) and dissolved inorganic carbon (DIC). 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 these data. Provide high-quality carbonate chemistry data (dissolved inorganic carbon and total alkalinity) for US coral reef areas at several spatial and temporal scales, in close partnership with the larger NOAA Ocean Acidification Observing Network including the Coral Reef Conservation Program (CRCP), National Coral Reef Monitoring Program (NCRMP), NOAA's Ocean Acidification Program (OAP), and NOAA's Pacific Marine Environmental Laboratory (PMEL) efforts.

NOAA National Centers for Environmental Information custodian bottle bottle any type of water bottle sampling device Generic name for water collection device; usually used to determine temperature, salinity and provide water aliquots for measurement of a wide range of parameters; often referred to by a specific type of water sampling bottle, such as a Nansen or Niskin bottle. coulometer for DIC measurement coulometer for DIC measurement measures dissolved inorganic carbon (DIC) A known amount of seawater is dispensed into a stripping chamber where it is acidified and purged with an inert gas. The amount of CO2 in the resulting gas stream is determined by absorbing the CO2 in an absorbent. The pH of the solution is monitored by measuring the transmittance . multi-parameter water quality sensor multi-parameter water quality sensor used to measure temperature, salinity, dissolved oxygen, and other parameters Instrument used to measure temperature, salinity, dissolved oxygen, and other parameters, often used to measure water quality parameters. Can be a hand-held instrument or a sonde for unattended monitoring. Often used in coastal water monitoring stations. YSI is the preeminent brand (as of 2024).
