Global Ocean Data Analysis Project (GLODAPv2)
GLODAP is an internally consistent data product for interior ocean “carbon relevant” variables, but in practice this means “everything that is measured from water samples” taken on hydrographic cruises that takes measurements of biogeochemistry, including inorganic carbon measurements. GLODAP was first published in 2004, and a new massively increased version, GLODAPv2, was published in 2016. A new version – GLODAPv2.2018 – will be published in early 2019.
GLODAP have three main products: 1) A collection of individual cruise file in a consistent format and 1st level QC, 2) A product that has been bias corrected through 2nd level QC procedures, and 3) an interpolated product on a regular grid.

Lineage Généalogie |
Global Ocean Data Analysis Project (GLODAP) version 2 includes data from approximately one million individual seawater samples collected from almost 800 cruises carried during the years 1972-2013. Extensive quality control and subsequent calibration were carried out for salinity, oxygen, nutrient, carbon dioxide, total alkalinity, pH and chlorofluorocarbon data. Following calibration, the data were used to produce global climatology maps for many of the parameters. In addition to the data products and the mapped distributions, all of the original data files without alteration other than formatting and unification of units are made freely available along with whatever metadata was collected. An on-line cruise summary table provides data access and additional information including references to publications that have used data from specific cruises. |
