Global Ocean Surface CO2 Partial Pressure Measurements from 1957-2013

Global oceans surface underway data collected from 1957-10 22 to 2013-03-21. It includes measurements of barometric pressure, partial pressure of carbon dioxide in water, salinity, and sea surface temperature. The data were collected by researchers from the Carbon Dioxide Information Analysis Center and Lamont-Doherty Earth Observatory using carbon dioxide gas analyzers.

Use Cases

• Modeling ocean carbon uptake based on partial pressure of CO2 measurements.
• Analyzing long-term trends in sea surface temperature and salinity.
• Studying correlations between atmospheric pressure and oceanic CO2 fugacity.
• Calibrating or validating global carbon cycle simulations.

Strengths

• Covers a long temporal range from 1957 to 2013.
• Includes multiple related variables: CO2 partial pressure, salinity, temperature, and barometric pressure.
• Data collected via surface underway measurements, providing spatial coverage across global oceans.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
