National Coral Reef Monitoring Program: Diel seawater carbonate chemistry observations from a suite of instrumentation deployed at coral reef sites in the Pacific Remote Islands Marine National Monument since 2015

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 during ESD-led missions at select sites in the Pacific Remote Island Areas. Diel surveys were conducted during NCRMP missions aboard NOAA Ship Hi'ialakai at Jarvis Island, Kingman Reef, and Palmyra Atoll from April 11-28, 2015 and again at Jarvis from April 2-6, 2017. Diel surveys were also conducted at Jarvis in collaboration with Anne Cohen’s lab at Woods Hole Oceanographic Institution during a special post-bleaching mission aboard NOAA Ship Oscar Elton Sette from May 16-23, 2016. The most recent diel surveys were conducted on the ESD-led cruise HA1801 at Baker Island, Jarvis Island, and Palmyra Atoll between June 12th-August 7th, 2018. Diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, dissolved oxygen, 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, an oxygen 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. 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.
