Global Ocean Data Analysis Project (GLODAP) data

Dataset

Glodap • Oceanography • Ocean Carbon Data • Ocean Chemistry Data

The Global Ocean Data Analysis Project (GLODAP) is a comprehensive, quality-controlled dataset of ocean interior biogeochemical observations, compiled from ship-based measurements collected over decades. It includes variables such as carbon dioxide (CO₂), total alkalinity,pH nutrients, oxygen, and more, from all major ocean basins.

More information

This dataset consists of the GLODAPv2.2022 data product composed of data from 1085 scientific cruises covering the global ocean between 1972 and 2021. It includes full depth discrete bottle measurements of salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon (TCO2), total alkalinity (TAlk), CO2 fugacity (fCO2), pH, chlorofluorocarbons (CFC-11, CFC-12, CFC-113, and CCl4), SF6, and various isotopes and organic compounds.

Designed to support global carbon cycle assessments, climate research, and ocean health monitoring, GLODAP data provides gridded products and individual cruise-level data ideal for model validation, trend analysis, and Earth system research.
