    • Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites in Batangas, Philippines from 2015-05-21 to 2015-05-31 (NCEI Accession 0189727)

    Metadata Updated: July 28, 2023

    The data provided in this data set are from diel surveys conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD)---formerly the Coral Reef Ecosystem Division---in the Philippines from May 21-31, 2015. The ocean acidification diel suite is an autonomous instrument package that measures diel variability in coral reef seawater carbonate chemistry. These diel suites were deployed on hard-bottom shallow-water (< 15 m) habitats at fixed climate survey sites located within coral reef ecosystems.

    The diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, temperature, pressure, pH, current direction and magnitude, and dissolved oxygen. 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 consisted of: 1 SBE-19plus CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, 1 SBE-43 oxygen sensor co-located with the CTD, and up to 9 Programmable Underwater Collectors (PUCs), each of which collected 1 water sample at 4-hour intervals. Instruments deployed, samples collected, and sample intervals are recorded in the meta file enclosed with the data package.
