    • Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites in Batangas, Philippines from May 21-31, 2015

    Metadata Updated: February 7, 2025

    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 dissolved 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 summary file in the data package.

    Lineage The ocean acidification diel suite is a collection of instruments deployed by SCUBA divers onto the seafloor that makes autonomous measurements and collects seawater samples. For a typical deployment, the diel suite consists of: 1 Sea Bird Electronics (SBE)-19plus CTD, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, 1 SBE 43 dissolved oxygen sensor, and up to 9 Programmable Underwater Collectors (PUCs), where each PUC collects 1 water sample at a 4-hour interval over a minimum 24-hour period. All instruments are weighted or zip-tied to rubble on the seafloor, or both, to secure the position of the instrumentation for the duration of the deployment.
