A compilation of published 230Thorium-normalized lithogenic and biogenic sediment fluxes from the Southern Ocean. Data includes opal and carbonate fluxes where available, with LGM values averaged from 28-18 ka BP and Holocene values from 10-0 ka BP. These records were collated for a modeling study of Southern Ocean ecosystem response to LGM boundary conditions.
Use Cases
- Modeling past Southern Ocean carbon cycling based on biogenic flux records.
- Comparing Last Glacial Maximum and Holocene sediment deposition patterns based on lithogenic flux data.
- Calibrating paleoclimate proxies using thorium-normalized flux compilation.
- Studying the relationship between ocean productivity and climate states based on opal and carbonate flux records.
Strengths
- Compilation spans the entire Southern Ocean south of 30°S.
- Includes both lithogenic and biogenic (opal, carbonate) flux components.
- Provides temporally averaged values for two distinct paleoclimate periods (LGM and Holocene).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data freshness should be verified despite the 2026-06-04 timestamp.
