Ifremer https://www.ifremer.fr/ HTTPS Ifremer website Institution web page information author NOAA National Centers for Environmental Information (NCEI) contributor tableDigital This dataset contains four companion digital models of the age, age uncertainty, spreading rates and spreading asymmetries of the world's ocean basins as geographic and Mercator grids with two-minute resolution. The grids include data from all the major ocean basins as well as detailed reconstructions of back-arc basins. NCEI decommissioned the Geological History of the World's Oceanic Crust in May 2025 with no further updates. Comments and questions may be sent to: ncei.info@noaa.gov. These new set of grids helps to investigate prominent negative depth anomalies, which may be alternatively related to subducted slab material descending in the mantle or to asthenospheric flow. A combination of our digital grids and the associated relative and absolute plate motion model with seismic tomography and mantle convection model outputs represents a valuable set of tools to investigate geodynamic problems. 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:0304215 Preview graphic PNG 0304215 NCEI ACCESSION NUMBER 2025-05-12 publication magnetometer instrument NODC INSTRUMENT TYPES THESAURUS geological model output theme NODC OBSERVATION TYPES THESAURUS NOAA National Centers for Environmental Information dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA National Centers for Environmental Information dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS World-Wide Distribution place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce 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.

Ages for ocean floor between the oldest identified magnetic anomalies and continental crust are interpolated by geological estimates of the ages of passive continental margin segments. asNeeded Metadata are developed, maintained and distributed by NCEI. Updates are performed as needed to maintain currentness.
