Title:

National Coral Reef Monitoring Program: Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites at Tutuila Island, American Samoa from 2015-03-06 to 2015-03-29 (NCEI Accession 0186951)

Abstract:

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 data set are from diel suites deployed at select sites at Tutuila Island between March 6 and March 29, 2015 during the ESD-led NCRMP mission to American Samoa in 2015. Diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, temperature, pressure, pH, and current direction and magnitude. Seawater samples were also collected 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. Each diel suite typically consisted of: 1 SBE-19plus CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, and up to 9 Programmable Underwater Collectors (PUCs), each of which collected 1 water sample at 3- or 4-hour intervals. Instruments deployed, samples collected, and sample intervals are recorded in the meta file enclosed with the data package, and exceptions to the standard diel suite are also noted.
