  • Release of GLODAPv2.2021
  • Release of GLODAPv2.2021

    On behalf of the GLODAP Reference Group, and hundreds of seagoing oceanographers that tirelessly have collected data all over the ocean, we are happy to announce the publication of GLODAPv2.2021. The Global Ocean Data Analysis Project (GLODAP) data product provides access to quality controlled surface to bottom ocean biogeochemical data, with an emphasis on seawater inorganic carbon. GLODAPv2.2021 is an update of the previous version, with 43 additional cruises, extension of time coverage until 2020, and the inclusion of DOIs for each individual cruise. GLODAPv2.2021 includes measurements from more than 1.3 million water samples from the global oceans collected on 989 cruises. The data for the 12 core variables have undergone extensive quality control, especially systematic evaluation of bias. The data are available in two formats: (i) as submitted by the data originator but updated to WOCE exchange format and (ii) as a merged data product with adjustments applied to minimize bias. 

     

    The original data, their documentation and doi codes are available at the Ocean Carbon Data System of NOAA NCEI. This site also provides access to the merged data product, which is provided as a single global file and as four regional ones. An accompanying manuscript has been submitted for consideration for publication in Earth System Science Data: https://essd.copernicus.org/preprints/essd-2021-234/. See also the GLODAPv2.2021 release poster.

    The IOCCP promotes the development of a global network of ocean carbon observations for research through technical coordination and communication services, international agreements on standards and methods, and advocacy and links to the global observing systems. The IOCCP is co-sponsored by the Scientific Committee on Oceanic Research and the Intergovernmental Oceanographic Commission of UNESCO. Read more…
