Laboratory experiments reveal calcification rates of crustose coralline algae (CCA) are strongly correlated to seawater aragonite saturation state. Predictions of reduced coral calcification rates, due to ocean acidification, suggest that coral reef communities will undergo ecological phase shifts as calcifying organisms are negatively impacted by changing seawater chemistry. The data described here are from water samples collected at existing, long-term monitoring sites during NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) led NCRMP missions around the American Samoa and the Pacific Remote Island Areas in 2012, the Hawaiian Archipelago in 2013, and Wake Island and the Mariana Archipelago in 2014. Two water samples are typically collected from each site—one at the reef and one at the surface directly above the reef—and a third sample may also be collected approximately 1 km offshore from the site. The samples are processed by ESD and sent to NOAA Pacific Marine Environmental Laboratory (PMEL) to be analyzed for total alkalinity (TA) and dissolved inorganic carbon (DIC). From these constituents, alongside temperature, salinity, and depth data, other constituents of the seawater carbonate system can be calculated. These monitoring data provide a baseline for tracking reef carbonate system changes due to globally increasing levels of atmospheric carbon dioxide. 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. To support a long-term Coral Reef Conservation Program for sustainable management and conservation of coral reef ecosystems and the NOAA Ocean Acidification Program (OAP), total alkalinity and dissolved inorganic carbon are measured to calculate various inorganic carbon system parameters that influence coral reef ecosystems monitored by the PIFSC Ecosystem Sciences Division (ESD). SCUBA divers take discrete water samples at the benthos and at the surface at forereef study sites established by the ongoing Pacific Reef Assessment and Monitoring Program (RAMP).

This integrated approach will consolidate 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), and many other partners. The PIFSC Ecosystem Sciences Division (ESD) at NOAA Fisheries is leading ocean and climate change monitoring in the U.S. Pacific Islands Region. 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 Reef Assessment and Monitoring Program (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. false eng false Spreadsheet Water Chemistry Entity 2018-11-30 publication CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact WWW:LINK-1.0-http--link NCEI Contact Information Information for contacts at NCEI. information distributor https://accession.nodc.noaa.gov/0131502 WWW:LINK-1.0-http--link OA_H2OSamples-MetadataEA.csv Data dictionary for the water chemistry dataset described herein, which includes a description of each column and it's domain values contained in the CSV file. download https://accession.nodc.noaa.gov/0157633 WWW:LINK-1.0-http--link PMEL_2010_SOP_DICandTA.pdf Discrete water sample collection protocol, established by the NOAA Pacific Marine Environmental Laboratory (PMEL). download https://accession.nodc.noaa.gov/0131502 WWW:LINK-1.0-http--link OA_H2OSamples(2012-2014).csv Water quality data from nearly 500 water samples collected by the PIFSC Ecosystem Sciences Division at 273 sites across the U.S.-affiliated Pacific Islands, including the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas between 2012 and 2014.

Comparability Since the carbonate system can vary on a diurnal scale and not all samples are taken at the exact same time of day, considering the time a sample was taken may be important for some analyses. However, because all samples are taken between 8:00 AM and 4:00 PM, variation due to diurnal change is expected to be small. Completeness Report All analyzed samples are included. Conceptual Consistency The data are very consistent, sample collection and processing protocols are adhered to very rigorously, both in the field and in the lab. PIFSC Ecosystem Sciences Division (ESD) assembles carbonate chemistry information from discrete seawater samples analyzed for two parameters: 1) Dissolved Inorganic Carbon (DIC), which in some literature is defined as Total Carbon (CT), and 2) Total Alkalinity (TA or AT). The carbonate system is influenced by seawater salinity, temperature, pressure, and the dissolved nutrients silicate (SiO44-) and phosphate (PO43-). All carbonate system collection and measurement methodologies follow the protocols accepted by the greater scientific community and outlined in Dickson et al. (2007) Discrete water samples are collected according to the protocol established by the NOAA Pacific Marine Environmental Laboratory (PMEL). Young, Charles W charles.young@noaa.gov processor PIFSC Ecosystem Sciences Division (ESD) collects supplementary salinity, temperature, and pressure values by deploying a Seabird Electronics SBE-19plus CTD in concert with every discrete seawater sample collection. Young, Charles W charles.young@noaa.gov processor NOAA Pacific Marine Environmental Laboratory (PMEL) supports PIFSC Ecosystem Sciences Division's (ESD) carbonate chemistry sampling through the laboratory analysis of dissolved inorganic carbon (DIC) and total alkalinity (TA), provision of the sample bottles and transport cases, and technical consultation. The source document contains the protocols that PMEL uses to analyze water samples for DIC and TA. The Total Alkalinity (TA) analysis employs a two-stage, potentiometric, open-cell titration using coulometrically analyzed HCl.
