Southern Ocean and Southwest Pacific data from 5 sediment traps moored from Subtropical to Polar Frontal environments. The dataset contains oxygen isotopic records from three planktonic foraminifera species, analyzed for seasonal flux patterns and compared to predicted calcite equations. It was published by the Australian Ocean Data Network and last updated in 2026.
Use Cases
- Calibrating paleotemperature equations based on the comparison of foraminiferal d18O to predicted calcite d18O.
- Modeling species-specific habitat depths based on seasonal d18O ranges and flux patterns.
- Assessing the preservation of seasonal signals in sedimentary records by comparing trap and surface sediment isotopic composition.
- Investigating the influence of carbonate chemistry on foraminiferal d18O offsets from predicted values.
Strengths
- Data spans a latitudinal gradient across 5 distinct sediment trap locations.
- Analysis includes three key foraminifera species: Globigerina bulloides, Globorotalia inflata, and Neogloboquadrina pachyderma (s.).
- Compares empirical data to established paleotemperature equations from Epstein et al. (1953) and Kim and O'Neil (1997).
- Reveals distinct seasonal flux patterns for each species, such as a spring peak for G. bulloides at 51°S.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update timestamp is from 2026.
