Australian Ocean Data Network hosts carbon isotopic composition measurements for three species of planktonic foraminifera collected from Southern Ocean sediment traps. The data represent annual flux in environments from the Subtropical to Polar Frontal zones in the western Pacific/Southern Australia sector. The dataset was last updated on 2026-04-16.
Use Cases
- Estimating the oceanic Suess effect based on modern depletion in d13C compared to core tops.
- Analyzing latitudinal trends in isotopic disequilibrium between foraminifera and dissolved inorganic carbon.
- Using corrected Globigerina bulloides d13C as a nutrient tracer in Southern Ocean environments.
- Comparing field-derived disequilibrium-temperature relationships with laboratory-based calibrations.
Strengths
- Data covers three distinct species of planktonic foraminifera: Globigerina bulloides, Globorotalia inflata, and Neogloboquadrina pachyderma.
- Sediment traps provide annual flux data across a latitudinal gradient from Subtropical to Polar Frontal environments.
- Comparison with nearby core-top samples allows estimation of modern isotopic depletion.
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 bias inherent to the western Pacific/Southern Australia sector.
