National Coral Reef Monitoring Program: Diel seawater carbonate chemistry observations from water samples and a CTD deployed at coral reef sites in the Main Hawaiian Islands from 2019-07-10 to 2019-07-30 (NCEI Accession 0240410)

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 Lanai and the Main Hawaiian Islands (MHI) between July 10th and July 30th during the ESD-led NCRMP mission to the Hawaiian Archipelago in 2019.

Two diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, temperature, pressure, dissolved oxygen, and photosynthetically active radiation (PAR). 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 oxygen sensor or stand-alone DO logger, 1 stand-alone PAR 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 meta file enclosed with the data package, and exceptions to the standard diel suite are also noted.

Purpose Manual seawater sampling and other National Coral Reef Monitoring Program (NCRMP) field monitoring efforts are limited to daylight hour operations. As a result, these data sets do not capture full 24-hour variability in coral reef physical and chemical environments. The ocean acidification diel suite was developed to increase the temporal resolution and coverage of oceanographic and carbonate chemistry measurements and contextualize daytime sampling within the full diel cycle. The NOAA National Coral Reef Monitoring Program (NCRMP) details a long-term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP is intended to coordinate various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA will be able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. NCRMP provides a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the CRCP and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), NOAA's Atlantic Oceanographic & Meteorological Laboratory (AOML), NOAA Coral Reef Watch, and many other partners. The Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) at NOAA Fisheries is leading in-situ climate monitoring in the U.S. Pacific Islands Region as part of the ongoing Pacific Reef Assessment and Monitoring Program (RAMP). The climate component of NCRMP in the Pacific provides a comprehensive view of climate change impacts on coral reef ecosystems and helps identify areas of resilience and vulnerability. The key indicators used to identify and monitor climate-driven trends include 1) thermal stress caused by changes in sea temperature, 2) ocean acidification resulting from changes in carbonate chemistry, and 3) ecological impacts by collecting data on coral growth rates, erosion, and community structure to understand the impacts of thermal stress and ocean acidification on the ecosystem. Each year, ESD scientists work closely with CRCP and partners during Pacific RAMP missions to collect data using moored oceanographic (subsurface temperature recorders) and ecological (calcification accretion units [CAUs] and autonomous reef monitoring structures [ARMS]) instruments stationed at fixed sites in the Pacific Ocean, and water samples collected by divers. The in-situ data and satellite-based observations are also used in modeling efforts. Innovative analysis techniques are used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region's resources and how they are changing over time.
