Last Interglacial Sea-Level History from Speleothems: A Global Standardized Database

A global standardized database of U-series dated speleothems capturing sea level during the last interglacial period. It was exported from The World Atlas of Last Interglacial Shorelines (WALIS) database. The dataset was authored by Oana-Alexandra Dumitru of Columbia University.

Use Cases

• Calibrate paleoclimate models based on sea-level indicators from speleothems.
• Reconstruct past coastal environments based on dated sea-level positions.
• Analyze global patterns of sea-level change during the last interglacial period.
• Validate geochronological techniques using U-series dating data.

Strengths

• Data is standardized globally, facilitating comparative analysis.
• Sourced from the authoritative WALIS database, a known paleoclimate resource.
• Focuses on the last interglacial period, a key paleoclimate benchmark.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
