Oxygen isotopic records from three planktonic foraminifera species collected by five sediment traps deployed across the Southern Ocean and Southwest Pacific. The dataset likely contains seasonal flux patterns and isotopic values for Globigerina bulloides, Globorotalia inflata, and Neogloboquadrina pachyderma (s.). The data was contributed by the Australian Ocean Data Network and was last updated in May 2026.
Use Cases
- Calibrating paleoclimate temperature reconstructions based on foraminifera oxygen isotope values.
- Analyzing seasonal habitat depth variations based on isotopic offsets between species.
- Testing carbonate chemistry models based on the lack of correlation with carbonate ion concentration.
- Comparing sedimentary record fidelity based on flux-weighted isotopic values from traps and surface sediments.
- Mapping latitudinal gradients in foraminifera seasonality based on trap locations from subtropical to polar frontal zones.
Strengths
- Data from five sediment traps providing a latitudinal gradient from subtropical to polar frontal environments.
- Analysis includes three distinct foraminifera species, allowing for interspecies comparison.
- The study compares results with two established isotopic prediction equations (Epstein et al., 1953 and Kim and O'Neil, 1997).
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 data_gov_au.
