National Coral Reef Monitoring Program: Dissolved inorganic carbon, total alkalinity, pH and other variables collected from surface discrete measurements using Coulometer, alkalinity titrator and other instruments from the Florida Keys, Puerto Rico, St. Thomas, St. John, and St. Croix USVI, from 2024-01-02 to 2024-12-26 (NCEI Accession 0308300)
This dataset contains carbonate chemistry data collected at both random locations and existing long-term sites in the Florida Keys, Dry Tortugas, Flower Garden Banks and Southeast Florida as part of the NOAA National Coral Reef Monitoring Program (NCRMP). 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.

National Coral Reef Monitoring Program: Dissolved inorganic carbon, total alkalinity, pH and other variables collected from surface discrete measurements using Coulometer, alkalinity titrator and other instruments from Guam and the Commonwealth of the Northern Mariana Islands, from 2022-04-12 to 2022-08-10 (NCEI Accession 0289902)

This dataset contains the National Coral Reef Monitoring Program carbonate chemistry data from Guam and the Commonwealth of the Northern Mariana Islands from 2022-04-12 to 2022-08-10. The project monitors changes to coral reef carbonate chemistry over time, at U.S.-affiliated Pacific coral reef sites, through quantifying key chemical parameters that are expected to change with ocean acidification. This effort addresses multiple OAP programmatic mission areas by maintaining the coral reef portion of the OA monitoring network and developing a procedure for data synthesis, assimilation, and distribution. Incorporating an interdisciplinary approach, this project collects, processes, analyzes, and stewards dissolved inorganic carbon (DIC) and total alkalinity (TA) water sample data to document seawater carbonate chemistry at Class 0, I, II, and III climate monitoring sites in coral reef areas of the U.S. Pacific region.
National Coral Reef Monitoring Program: Water chemistry collected at Moored Autonomous Partial Pressure of Carbon Dioxide (MAPCO2) buoys in the Pacific Ocean
공공데이터포털
This collection contains carbonate chemistry data collected at fixed sites in the Pacific Ocean as part of calibration and validation for Moored Autonomous Partial Pressure of Carbon Dioxide (MAPCO2) buoys. 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.
National Coral Reef Monitoring Program: Calcification data derived from coral core measurements for La Parguera Reef in Puerto Rico between 1991 and 2015 (NCEI Accession 0177878)
공공데이터포털
This archive package contains long-term calcification data from coral cores extracted from La Parguera Reef in Puerto Rico as part of the NOAA Coral Reef Conservation Program’s (CRCP’s) National Coral Reef Monitoring Program (NCRMP). Corals annually form bands within their skeletons that manifest as high-density lines perpendicular to their growth axes. By precisely measuring the spacing and density of these bands, scientists can obtain a record of linear extension and skeletal density, respectively. Linear extension and skeletal density are, in turn, used to calculate annual calcification. Cores are collected by diver, underwater, using a pneumatic drill rig. Once removed, the small (~5 cm diameter) lesions are plugged with epoxy, and the resulting cores are analyzed using computed tomography (CT). Coral core data included herein were collected at long-term monitoring sites by the Acidification Calcification and Coral Reef Ecosystems Team (ACCRETE), based at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML).
