National Coral Reef Monitoring Program: Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites across American Samoa
The ocean acidification diel suite is an autonomous instrument package that measures diel variability in coral reef seawater carbonate chemistry. Diel suite surveys are conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) within coral reef ecosystems across the Pacific Islands Region as part of the NOAA National Coral Reef Monitoring Program (NCRMP). The data provided in this dataset are from diel suites deployed at select sites at Tutuila Island since 2015, during the ESD-led NCRMP missions to American Samoa. Diel suites are deployed on the reef for at least 24 hours to measure chemical and physical parameters at each site. Each diel suite typically consists of various sensors and up to 9 Programmable Underwater Collectors (PUCs) and/or Sub-surface Automated Samplers (SAS). The oceanographic sensors of each diel suite measure parameters such as salinity, temperature, pressure, pH, current direction and magnitude, dissolved oxygen (DO), and/or photosynthetically active radiation (PAR). Seawater samples are collected in four-hour intervals for laboratory analyses of dissolved inorganic carbon (DIC) and total alkalinity (TA). Components of the carbonate system--including pH, pCO2 (partial pressure of carbon dioxide), and aragonite saturation state--are calculated from DIC, TA, temperature, salinity and pressure. Exceptions to the traditional diel suite survey and data collected are noted in each dataset as sensors could be added, removed, or have malfunctioned.

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.

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.
