    • National Coral Reef Monitoring Program: Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites across the Hawaiian Archipelago since 2016

    Metadata Updated: October 19, 2024

    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 record are from diel suites deployed across the Hawaiian Archipelago since 2016 during ESD-led NCRMP missions. Specifically, at select sites at Kure Atoll and Lisianski Island between September 14th - 26th, 2016 as well as Lanai and the Main Hawaiian Islands between July 10th - July 30th, 2019.

    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 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 4-hour intervals; however, only data from the CTD and water samples were recovered from the diel surveys at Kure and Lisianski in 2016. Starting 2018, 1 SBE-43 oxygen sensor was tethered to the CTD sensor for diel surveys. Stand-alone dissolved oxygen (DO) and photosynthetically active radiation (PAR) loggers were included with the diel suite deployments starting HARAMP 2019. Instruments deployed, samples collected, and sample intervals are recorded in the summary file enclosed with the data package, and exceptions to the standard diel suite are also noted.

    Lineage The Ocean Acidification Diurnal Suite is a collection of instruments deployed by SCUBA divers onto the seafloor that makes autonomous measurements and collects seawater samples. For a typical 24 hour sampling, the diurnal suite consists of: 1 Sea Bird Electronics (SBE)-19plus CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, and 7 Programmable Underwater Collectors (PUC), where each PUC collects 1 discrete water sample at a 4-hour interval from 12:00 on day 1 to 12:00 on day 2. Starting 2018 an oxygen sensor was co-located with the CTD sensor, and beginning in 2019 a stand-alone PAR sensor as well as oxygen sensor were added to the deployment. 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. Instruments 3-7 were not in the diel suite package for the 2016 deployment.
