High quality, reference measurements of chemical and physical properties of seawater are of great importance for a wide research community, including the need to validate models and attempts to quantify spatial and temporal variability. Whereas data precision has been improved by technological advances, the data accuracy has improved mainly by the use of certified reference materials (CRMs). However, since CRMs are not available for all variables, and use of CRMs does not guarantee bias-free data, we here present a recently developed Matlab toolbox for performing so-called secondary quality control on oceanographic data by the use of crossover analysis. This method and how it has been implemented in this toolbox is described in detail. This toolbox is developed mainly for use by sea-going scientists as a tool for quickly assessing possible bias in the measurements that can, hopefully, be remedied during the expedition, but also for possible post-cruise adjustment of data to be consistent with previous measurements in the region. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0209357 Preview graphic PNG 0209357 NCEI ACCESSION NUMBER 2020-03-20 publication CHLOROFLUOROCARBON (CFC) DISSOLVED INORGANIC CARBON (DIC) NUTRIENTS OXYGEN partial pressure of carbon dioxide - water pH SALINITY total alkalinity WATER TEMPERATURE theme NODC DATA TYPES THESAURUS carbon dioxide (CO2) gas analyzer CTD Niskin bottle titrator instrument NODC INSTRUMENT TYPES THESAURUS chemical discrete sample physical profile theme NODC OBSERVATION TYPES THESAURUS UNKNOWN PLATFORMS OF USSR platform NODC PLATFORM NAMES THESAURUS Bjerknes Centre for Climate Research GEOMAR Helmholtz Centre for Ocean Research Kiel dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS University of Bergen dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Climate Variability and Predictability (CLIVAR) GLOBAL OCEAN DATA ANALYSIS PROJECT (GLODAP) The Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) World Ocean Circulation Experiment (WOCE) project NODC PROJECT NAMES THESAURUS World-Wide Distribution place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication BJERKNES > Bjerknes Centre for Climate Research DE/GEOMAR > GEOMAR - Helmholtz Centre for Ocean Research Kiel, Germany dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian 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.
