Global Standardized Database of Last Interglacial Sea Level Records

Records from approximately 130,000 to 75,000 years ago capture sea level using U-series dated cave deposits. The data is a global standardized database exported from The World Atlas of Last Interglacial Shorelines (WALIS). It was authored by Oana-Alexandra Dumitru of Columbia University.

Use Cases

• Calibrate paleoclimate models based on dated sea-level indicators.
• Analyze global sea-level variability during the Last Interglacial period.
• Train machine learning models to predict future sea-level rise using paleo-data.
• Correlate speleothem (cave deposit) ages with other paleoclimate proxies.

Strengths

• Data is globally standardized, facilitating comparative analysis.
• Records cover a significant time range of ~55,000 years during the Last Interglacial.
• Sourced from the authoritative WALIS database, indicating a curated origin.

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.
