On behalf of the GLODAP Reference Group, and hundreds of seagoing oceanographers who tirelessly have collected data all over the ocean, we are happy to announce the publication of GLODAPv2.2023.

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. GLODAPv2.2023 is an update of the previous version, with 23 additional cruises and includes measurements from more than 1.4 million water samples from the global oceans collected on 1108 cruises. The data for the 13 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.

More details about GLODAP background as well as the v2.2023 release poster can be found here.

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, and access to the GLODAPv2.2023 ODV collection.

We hope this update will be valuable for your research, and we welcome any feedback on the product.
