Oceanic Anthropogenic CO2 Sink: 1994-2007 Change Estimates

1994 to 2007 estimates of the change in anthropogenic CO2 (Cant) stored in the global ocean, derived from the GLODAPv2 product using the eMLR(C*) method. The dataset includes a standard estimate and 13 sensitivity cases, provided as 3D distributions and column inventories on a 1x1 degree grid. These data constrain the ocean's role in the global carbon cycle and are useful for assessing ocean acidification and evaluating carbon cycle models.

Use Cases

• Constraining the global land carbon sink magnitude based on ocean carbon inventory changes.
• Assessing regional ocean acidification trends using 3D anthropogenic CO2 concentration data.
• Evaluating ocean general circulation model performance on carbon uptake and storage.
• Analyzing the sensitivity of carbon sink estimates to methodological choices via the 13 provided sensitivity cases.

Strengths

• Includes 13 sensitivity cases to assess the robustness of the core estimate.
• Provides data at a consistent 1x1 degree spatial resolution for global analysis.
• Based on the established GLODAPv2 product and a peer-reviewed method (eMLR(C*)).

Limitations

• Key metadata conflicts: last updated date is reported as both 2007-12-31 and 2026-03-05.
• Column names and exact row/table dimensions are not provided in any source.
• Dataset size and specific license information are unknown.
