This tool complements ongoing geochemical surveys and monitoring efforts in the region by providing estimates of changing ocean chemistry on a broader spatial and temporal scale than shipboard observations alone can permit. The maps presented here are monthly averages of daily estimates derived according to Gledhill et al., 2008. Near-real-time estimates are modeled from daily fields of NOAA Optimum Interpolation Advanced Very High Resolution Radiometer - Advanced Microwave Scanning Radiometer (AVHRR-AMSRE) SST, Hybrid Coordinate Ocean Model + Navy Coupled Ocean Data Assimilation (HYCOM + NCODA) modeled sea surface salinity (SSS), NOAA National Centers for Environmental Predication (NCEP) sea-level pressure (SLP), and estimates of atmospheric CO2 derived from the NOAA Earth System Research Laboratory GLOBALVIEW-CO2 reference marine boundary layer (MBL). The parameters provided in this data set include sea surface temperature (SST), sea surface salinity (SSS), partial pressure of carbon dioxide for seawater (pCO2sw), total alkalinity (TA), total inorganic carbon (TC), pH, aragonite saturation state (SSA), bicarbonate ion concentration (HCO3), and carbonate ion concentration (CO3). All parameters are provided at monthly, 25km resolution. The global oceans are the largest natural reservoir for excess carbon dioxide in the atmosphere, absorbing approximately one third of that attributed to human activities each year. As a result, dissolved CO2 in the surface ocean will likely double over its pre-industrial value by the middle of this century, representing perhaps the most dramatic change in ocean chemistry in over 20 million years. In coming decades, ocean acidification could affect some of the most fundamental biological and geochemical processes of the sea. The purpose of this dataset is to contribute to the understanding of changing ocean chemistry and its relationship to climate. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:CRW-OAPS Preview graphic PNG 0072302 0074924 0075238 0075239 0075240 0075241 0075242 0075243 0075244 0075245 0075246 0075247 0075248 0075249 0075250 0075251 0075252 0075253 0075254 0075255 0075256 0075257 0075258 0075259 0089061 NCEI ACCESSION NUMBER 2012-05-04 publication ARAGONITE SATURATION STATE CARBON - BICARBONATE CARBON - CARBONATE DISSOLVED INORGANIC CARBON (DIC) partial pressure of carbon dioxide - water pH SALINITY - SURFACE WATER SEA SURFACE TEMPERATURE total alkalinity WATER TEMPERATURE theme NODC DATA TYPES THESAURUS model output satellite data theme NODC OBSERVATION TYPES THESAURUS NOAA Atlantic Oceanographic and Meteorological Laboratory NOAA Center for Satellite Applications and Research dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Center for Satellite Applications and Research dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Coral Reef Information System (CoRIS) CORAL REEF STUDIES Coral Reef Watch (CRW) project NODC PROJECT NAMES THESAURUS Caribbean Sea Gulf of Mexico North Atlantic Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NODC > National Oceanographic Data Center, NESDIS, NOAA, U.S. Department of Commerce DOC/NOAA/NESDIS/STAR > Center for Satellite Applications and Research, NESDIS, NOAA, U.S. Department of Commerce DOC/NOAA/OAR/AOML > Atlantic Oceanographic and Meteorological Laboratory, OAR, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
