The NOAA Coral Reef Watch Experimental Ocean Acidification Product Suite (OAPS) offers an important synthesis of satellite and modeled environmental datasets to provide a synoptic estimate of sea surface carbonate chemistry in the Greater Caribbean Region. 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 + Navey 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 alkilinity (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., More information.
