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. 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 CREP 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 NOAA Coral Reef Ecosystem Program (CREP). 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).

You can bypass ERDDAP's web pages and use ERDDAP's RESTful web services (for example, for searching for datasets, for downloading data, for making maps) directly from any computer program (for example, Matlab, R, or a program that you write) and even from web pages (via HTML image tags or JavaScript). CRCP Pacific Carb Chem ERDDAP acts as a middleman between you and various remote data servers. ERDDAP offers an easy-to-use, consistent way to request data: via the OPeNDAP standard. Many datasets can also be accessed via ERDDAP's Web Map Service (WMS). ERDDAP returns data in the common file format of your choice. ERDDAP offers all data as .html table, ESRI .asc and .csv, Google Earth .kml, OPeNDAP binary, .mat, .nc, ODV .txt, .csv, .tsv, .json, and .xhtml. download https://doi.org/10.25921/nnk7-5f86 HTTPS Web browser NCEI Dataset Landing Page Navigate directly to the URL for a descriptive web page with download links. information https://www.ncei.noaa.gov/metadata/granule/geoportal/?from=0&size=10&esdsl=%7B%22query%22%3A%7B%22bool%22%3A%7B%22must%22%3A%5B%7B%22query_string%22%3A%7B%22analyze_wildcard%22%3Atrue%2C%22query%22%3A%22fileid%3ANCRMP-CO3-Pacific.*%22%7D%7D%5D%7D%7D%7D#searchPanel HTTPS Web browser Granule Search Search for data granules belonging to this collection (a granule is the smallest aggregation of data that can be independently described and retrieved). search series NCEI Accession 0131502 v1.1 was published. 2015-11-16T14:59:08Z NCEI Accession 0159169 v1.1 was published. 2017-03-01T13:34:12Z NCEI Accession 0159171 v1.1 was published. 2017-03-01T13:53:42Z NCEI Accession 0160330 v1.1 was published. 2017-03-01T21:58:09Z NCEI Accession 0157716 v1.1 was published. 2017-03-28T17:07:08Z NCEI Accession 0157715 v1.1 was published. 2017-03-28T17:08:07Z NCEI Accession 0157714 v1.1 was published. 2017-03-28T17:10:07Z NCEI Accession 0157716 was revised and v2.2 was published. 2017-04-04T17:31:22Z NCEI Accession 0157715 was revised and v2.2 was published. 2017-04-04T17:32:05Z NCEI Accession 0157714 was revised and v2.2 was published. 2017-04-04T17:33:05Z NCEI Accession 0175227 v1.1 was published. 2018-08-20T19:00:11Z NCEI Accession 0175228 v1.1 was published. 2018-08-20T19:00:14Z NCEI Accession 0175229 v1.1 was published. 2018-08-23T19:47:13Z NCEI Accession 0175230 v1.1 was published. 2018-08-23T19:55:14Z NCEI Accession 0225980 v1.1 was published. 2021-03-09T14:04:21Z NCEI Accession 0226976 v1.1 was published. 2021-03-23T12:17:09Z NCEI Accession 0226794 v1.1 was published. 2021-03-23T17:41:03Z NCEI Accession 0175227 was revised and v2.2 was published. 2021-03-25T19:59:20Z NCEI Accession 0225980 was revised and v2.2 was published. 2021-03-29T14:39:30Z NCEI Accession 0175228 was revised and v2.2 was published. 2021-03-30T19:22:10Z NCEI Accession 0175229 was revised and v2.2 was published. 2021-04-01T19:51:24Z NCEI Accession 0157714 was revised and v3.3 was published. 2021-04-13T18:49:11Z NCEI Accession 0175230 was revised and v2.2 was published. 2021-04-13T18:54:10Z NCEI Accession 0157716 was revised and v3.3 was published. 2021-04-16T18:17:11Z NCEI Accession 0157715 was revised and v3.3 was published. 2021-04-16T18:44:12Z NCEI Accession 0159169 was revised and v2.2 was published. 2021-04-27T01:26:26Z NCEI Accession 0159171 was revised and v2.2 was published. 2021-04-27T16:39:12Z NCEI Accession 0160330 was revised and v2.2 was published. 2021-05-03T22:45:11Z NCEI Accession 0283239 v1.1 was published. 2023-09-28T17:15:27Z NCEI Accession 0302040 v1.1 was published. 2025-03-03T19:32:31Z NCEI Accession 0302039 v1.1 was published. 2025-03-03T19:38:30Z NCEI Accession 0306674 v1.1 was published. 2025-08-01T16:02:37Z NCEI Accession 0310598 v1.1 was published. 2025-12-16T21:57:08Z NCEI Accession 0310600 v1.1 was published. 2025-12-16T21:57:30Z asNeeded Metadata are developed, maintained and distributed by NCEI.

NOAA National Centers for Environmental Information custodian bottle bottle any type of water bottle sampling device Generic name for water collection device; usually used to determine temperature, salinity and provide water aliquots for measurement of a wide range of parameters; often referred to by a specific type of water sampling bottle, such as a Nansen or Niskin bottle. carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water. coulometer for DIC measurement coulometer for DIC measurement measures dissolved inorganic carbon (DIC) A known amount of seawater is dispensed into a stripping chamber where it is acidified and purged with an inert gas. The amount of CO2 in the resulting gas stream is determined by absorbing the CO2 in an absorbent. The pH of the solution is monitored by measuring the transmittance . CTD CTD Conductivity-Temperature-Depth probe Niskin bottle Niskin bottle Device for obtaining samples of seawater at a specific depth Why special entry for Niskin bottle but no entry for Nansen bottle? pH sensor pH sensor generic meter used to measure pH Any of a class of instruments used to quantify pH in a water or other type of sample. salinometer salinometer generic salinometer use salinometer when the instrument type used is unclear but the data include salinity measurements temperature sensor temperature sensor A sensor used to measure temperature. thermometer thermometer generic thermometer or reversing thermometer use thermometer when temperature is a data type, but the exact instrument used to measure temperature is unknown thermosalinograph thermosalinograph automated sea surface temperature and salinity instrument, usually attached to the hull of a ship Thermosalinograph is an automated Sea Surface Temperature and Salinity measurement system making measurement on board a ship using a water intake.
