Description
Sediment samples from the epicontinental Laurasian Seaway provide thallium (Tl) isotope evidence for changes in global manganese oxide burial between 150 and 149 million years ago. The dataset, authored by Andrew Aplin and shared under a CC-BY-4.0 license, suggests fluctuations in marine deoxygenation occurred on 10,000 to 100,000-year timescales. It is stored in an XLSX file sized 34.4 KB.
Use Cases
Modeling ancient marine oxygen levels based on inferred manganese oxide burial rates.
Analyzing thallium isotope signatures as a proxy for global marine deoxygenation events.
Investigating the decoupling of carbon cycle shifts from marine hypoxia during the Late Jurassic.
Studying the temporal resolution of paleoclimate events on 10,000 to 100,000-year scales.
Strengths
Data is focused on a specific 1-million-year interval (150-149 Ma) from a named geological core (Ebberston-87).
The description provides a concrete scientific inference, suggesting reductions of up to 70% in Mn oxide burial.
The dataset is openly licensed under CC-BY-4.0.
Limitations
Row count is unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
The dataset is very small at 34.4 KB, indicating limited scope.
