54927 NCRMP: Diel Marianas Data Set Published / External 32957 Marianas Archipelago Project On Going 2019 2024 2024 The diel suite is an autonomous instrument package that measures diel variability in coral reef oceanographic conditions and 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 sites in Guam, Aguijan, Maug, and Pagan, Mariana Archipelago in 2017 and 2022. Diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, temperature, pressure, pH, current direction and magnitude, 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 typically consisted of: 1 SBE-19plus or RBR concerto3 CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, 1 SBE or RBR dissolved oxygen sensor (2022 only), 1 RBR photosynthetically active radiation sensor (2022 only), 1 tilt current meter (2022 only), and up to 9 Programmable Underwater Collectors (PUCs, 2017) or Sub-surface Automated Samplers (SAS, 2022), each of which collected a water sample at set 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. 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.

Updated in 2021 with new columns and updated field data. Updated in 2024 with data collected in 2022. Table (digital) CTD data include conductivity, temperature, and pressure observations with calculated depth, salinity, and density. Water samples are analyzed for dissolved inorganic carbon (DIC) and total alkalinity (TA). pH, partial pressure of carbon dioxide, and aragonite saturation state are mathematically derived from TA and DIC values using temperature, salinity, and pressure data from the CTD (if available). If no CTD data are available, temperature and salinity may be estimated from the ship's Scientific Computer System or from bottle samples (salinity only). pH data are the mean of a burst of 30 measurements collected every 5 minutes. ADCP current magnitude (meters/second) and direction (degrees) data are binned into 1-m height bins represented by the height of each bin above the sensor on the seafloor. Tilt current meter current speed and direction are only available for one bin ~1m above the benthos. Dissolved oxygen data include oxygen percent saturation and concentration. While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

See Lineage Process Steps for additional information on data processing for each instrument. Seawater carbonate chemistry at the benthos is dynamic and driven by physical and biological processes occurring at time scales of minutes to days. The measurements and analyses from this instrument suite is representative of the water column chemistry at the time of measurement, but this highly variable environment allows for a fairly wide distribution of measured values. Water samples: accuracy of seawater carbonate chemistry laboratory analysis is explained in detail in Dickson et al (2007), SOP #2: Determination of total dissolved inorganic carbon in sea water, and SOP #3b: Determination of total alkalinity in sea water using an open-cell titration. Satlantic SeaFET Ocean pH sensor: measurement range: 6.5-9.0 pH; salinity range: 2-40 psu; accuracy: +/- 0.05 pH; precision: better than 0.001 pH; resolution: 0.0001 pH; stability: 0.005 pH/mo SBE-19plus CTD sensor: -Conductivity - measurement range: 0-9 S/m; accuracy: +/- 0.0005 S/m; stability: 0.0003 S/m per month; resolution: 0.00005 S/m; -Temperature - measurement range: -5-35 deg C; accuracy: +/-0.005 deg C; stability: 0.0002 deg C per month; resolution: 0.0001 deg C; -Pressure - measurement range: 0-600 m; accuracy: +/- 0.1%; stability: +/- 0.1%; resolution: 0.002% Nortek Acoustic Doppler Current Profiler 1MHz: Profiling range: 12-25 m; accuracy: +/- 1% RBR solo3 dissolved oxygen sensor: calibrated range: 0 to 600 %; accuracy: +/- 2 % RBR solo3 PAR sensor: wavelength range: 400 to 700 nm; calibrated range: 0 to 10000 umol/m2/s; accuracy +/- 2% Lowell tilt current meter: range: 0-80 cm/s; accuracy: 3 cm/s + 3% of reading The entire suite of instrumentation is deployed during diel surveys; however, various issues can occur with any one or several of the instruments during the deployment thereby limiting the data recovered. Refer to the 'summary' file enclosed with the data package for details. Redundant data are collected to ensure accuracy of the methods/instrumentation. pH is captured from the discrete water samples and pH sensor. Pressure is captured by the ADCP and the CTD. Temperature is captured by the pH sensor and the CTD. For some deployments, paired water samples are collected simultaneously at the benthos and 1.5 meters above the seafloor. All analyzed samples and measured values are included. NULL values in the data, where they exist, indicate that the observation/analysis was not conducted for the sample record where it appears. The data are very consistent, sample collection and processing protocols detailed in Dickson et al (2007) are adhered to rigorously, both in the field (SOP #1) and in the laboratory (SOP #2 and #3b). The data is quality controlled by NOAA PIFSC Ecosystem Sciences Division (ESD) personnel after the data is downloaded from the instruments, after it is migrated to the database, and once again when the data are submitted to the NOAA National Centers for Environmental Information. NOAA Pacific Marine Environmental Laboratory (PMEL) conducts quality assurance and quality control on their seawater analyses according to protocols #2 and #3b in Dickson et al (2007). Yes Unknown Yes No Unknown NCEI-MD Unknown The data is captured in several locations: files stored on the cruise server during the mission and the PIFSC network, and some of the data are imported into the PIFSC Oracle database. The cruise server is regularly backed up by the cruise data manager while at sea, and the PIFSC network and Oracle database are maintained and regularly backed up by PIFSC ITS. 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 SBE-19plus or RBR concerto3 CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, 1 dissolved oxygen sensor, 1 photosynthetically active radiation sensor, 1 tilt current meter, and up to 9 Programmable Underwater Collectors (PUCs) or Subsurface Automated Samplers (SAS), each of which collected a water sample at set intervals. 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.

PICES Special Publication 3, 191 pp. 2007-10-01 https://www.nodc.noaa.gov/ocads/oceans/Handbook_2007.html Ocean Carbon Data System (OCADS), Access Data Guide to Best Practices for Ocean CO2 Measurements Dickson et al (2007) Protocols to collect, process, and analyze water samples for DIC and TA: SOP 1: Water Sampling for the parameters of the oceanic carbon dioxide system SOP 2: Determination of total dissolved inorganic carbon in sea water SOP 3b: Determination of total alkalinity in sea water using an open-cell titration 1 Water samples collected with Programmable Underwater Collectors (PUC) or Sub-surface Automated Samplers (SAS). PUC and SAS have computerized timers attached to a low-power peristaltic pump. An array of samplers collects water at approximately 4-hour intervals over the course of at least 24-hours, usually starting at 12:00 pm local time on day 1 and ending at 12:00 pm on day 2. While samplers are programmed to collect water on this regular sampling schedule, issues with the pumps can occasionally result in missing samples for some of the time steps. For some deployments, paired water samples were collected simultaneously at the benthos and 1.5 meters above the seafloor. Samples are collected underwater in tedlar bags pre-poisoned with mercuric chloride and transferred to glass bottles within a few hours of recovery. Water samples are analyzed for DIC using a coulometer (SOP #2) and for TA using a titrator (SPO #3b) by the NOAA Pacific Marine Environmental Laboratory. On occasion, poor pump performance results in half-filled sample bags. These samples are only analyzed for TA due to insufficient sample volume for DIC analysis. Full carbon system chemistry values (including pH, pCO2, and aragonite saturation state) are derived from DIC/TA and salinity/temperature/pressure data from a co-deployed CTD using the R package seacarb. Discrete sample pH data are compared to SeaFET pH data. Temperature and salinity values are typically derived from a moored CTD ("TEMPERATURE_ITS90_CTD" and "SALINITY_PSS78_CTD"). If no CTD data are available, alternate temperature and salinity values are substituted from the ship's Scientific Computer System (SCS, "TEMPERATURE_ITS90_SCS" or "SALINITY_PSS78_SCS"). Salinity values may also be measured from bottle samples ("SALINITY_PSS78_BOTTLE"). All data columns are present in the dataset to maintain consistency across diel suite deployments, but may be NULL for all entries in a particular dataset if temperature/salinity were not collected using the specified method for that deployment year. In the water sample data files, "TEMPERATURE_ITS90_BEST"/"TEMPERATURE_ITS90_BEST_ORIGIN" and "SALINITY_PSS78_BEST"/"SALINITY_PSS78_BEST_ORIGIN" indicate the temperature and salinity used for carbonate chemistry calculations and the source from which each value was derived.

PICES Special Publication 3, 191 pp. 2 Acoustic Doppler Current Profiler (ADCP) sensor The diel suite includes either a 1.0 MHz or a 2.0 MHz side-looking ADCP (1.0 MHz ranges 20-m depth, while the 2.0 MHz ranges 10-m). ADCP measurements are collected at 10 minute intervals and binned by height above the sensor. Each height bin is represented in the data set as the upper limit of the bin height above the sensor on the seafloor (for example, a 1.4 m bin represents current data collected between 0.4 m and 1.4 m above the ADCP). ADCP data include a blanking region, or a small distance in front of the transducer in which measurements cannot be made, of 0.2-0.4 m. Current data are grouped into 1-m height bins. Raw data downloaded from the ADCP are processed in R using the oce package. XYZ coordinate data are converted to ENU (east-north-up) coordinate system. Current speed is calculated as the square root of the sum of the squared u and v velocities and direction as the arctan(v/u). Data are trimmed to a maximum height bin for each time step using pressure data to remove above-water signal. As a result, NULL values may exist for larger height bins above the surface of the water due to waves and tides.

The electrode is conditioned in running seawater up to a week prior to deployment and stored in artificial seawater between deployments. pH data are collected in bursts of 30 measurements every 5 minutes. The SeaFET is co-deployed with a CTD, and temperature and salinity values from the CTD time series are used to correct the raw pH time series. The SeaFET derives pH from both internal and external potentiometric cells, but only internal pH is reported. SeaFET pH values are compared to pH values calculated from discrete TA and DIC samples collected at the same time and location.
