Global Ocean Carbon-13 Measurements in Dissolved Inorganic Carbon, 1990-2005

A global compilation of Carbon-13 isotope measurements in dissolved inorganic carbon (d13C_DIC) from 1990 to 2005. The dataset, calculated by Andreas Schmittner of Oregon State University, includes associated water temperature, phosphate, and silicate measurements. These data provide a 15-year record for studying ocean carbon cycling and its interaction with climate.

Use Cases

• Calibrating ocean carbon cycle models based on d13C_DIC measurements.
• Analyzing temporal trends in ocean carbon isotopes based on the 1990-2005 time range.
• Studying correlations between carbon isotopes and ocean nutrients like phosphate and silicate.
• Investigating global ocean carbon uptake and storage using isotopic signatures.

Strengths

• Data covers a 15-year period (1990-2005) for temporal trend analysis.
• Includes multiple related variables: d13C_DIC, water temperature, phosphate, and silicate.
• Dataset is a global compilation, offering wide spatial coverage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the original compilation sources.
