Ventilation age is defined as the time elapsed since a water parcel was last in contact with the atmosphere. Our calculated ages are estimated from measured concentrations of the transient tracers sulphur hexafluoride (SF6), and the chlorofluorocarbons (CFCs) CFC-11 and CFC-12. For these TTD calculations we have assumed full (100%) saturation of the transient tracers when subducted, which will generate a bias toward older ages in especially dense water formation regions since it is known that the saturation there is frequently lower than 100%. We assume that the solution to the Greens function is an Inverse Gaussian (IG) function. Furthermore, we have assumed a balance between advection and mixing, i.e., unity ratio between the width and the mean age of the TTDs. This assumption is typically adopted in the global ocean (e.g., Waugh et al., 2006), although there is regional variability (e.g., Stöven and Tanhua, 2014; Rajasakaren et al., 2019). Thus, some care should be taken when utilising the calculated ages in certain regions. The main reason for the published dataset is to give a user-friendly product that can be applied in ocean studies where ventilation ages are of interest, both to give an appreciation of typical ages and gradients in the ocean, and to be adopted in studies calculating biogeochemical rates. A recent example of the latter is the updated calcium carbonate dissolution study by Sulpis et al. (2021), which used these data. All included data are listed and specified in the dataset description below, and most of them are identical to the values found in GLODAPv2 (Key et al., 2015; Olsen et al., 2016). The novel addition in this dataset are the ventilation ages. The files contain both the TTD-based mean ages that are calculated as described above, and, calculated tracer ages, which assumes no mixing and are simply derived by matching the observed tracer concentration to the atmospheric history. For the atmospheric history we used (Walker et al. (2000) and Bullister (2015)), updated to 2016 by extrapolating with the same atmospheric evolution rate as the year before. The dataset consists of files covering four regions, following the GLODAPv2 data synthesis product: the Arctic Mediterranean (ARC), The Atlantic Ocean (ATL), the Indian Ocean (IND), and the Pacific Ocean (PAC). The data are provided both in comma separated (.csv) format and in Matlab® format (.mat). 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:0226793 Preview graphic PNG 0226793 NCEI ACCESSION NUMBER 2021-03-11 publication BAROMETRIC PRESSURE CHLOROFLUOROCARBON-11 (CFC-11) CHLOROFLUOROCARBON-12 (CFC-12) Potential temperature (theta) SALINITY sulfur hexafluoride (SF6) WATER TEMPERATURE theme NODC DATA TYPES THESAURUS CTD Niskin bottle titrator instrument NODC INSTRUMENT TYPES THESAURUS chemical discrete sample physical profile theme NODC OBSERVATION TYPES THESAURUS VARIOUS CHARTERED VESSELS platform NODC PLATFORM NAMES THESAURUS Bjerknes Centre for Climate Research dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS Bjerknes Centre for Climate Research dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS GLOBAL OCEAN DATA ANALYSIS PROJECT (GLODAP) The Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) U.S. Climate Variability and Predictability Research Program (U.S. CLIVAR) World Ocean Circulation Experiment (WOCE) project NODC PROJECT NAMES THESAURUS Arctic Ocean Indian Ocean North Atlantic Ocean North Pacific Ocean South Atlantic Ocean South Pacific Ocean Southern Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication BJERKNES > Bjerknes Centre for Climate Research dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 23 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.
