Sea Level Time Series at Socoa, France, from 1875 to Present

Socoa tide gauge in Saint Jean-de-Luz, France provides high-temporal-resolution sea level observations. The dataset, created by researchers including Md Jamal Uddin Khan and Guy Woppelmann, extends the time series back to 1875. It includes raw and multiple processed data levels, auxiliary data from Brest and Santander, and supporting documents.

Use Cases

• Analyzing long-term sea level trends based on the extended time series from 1875.
• Comparing sea level changes between different coastal stations based on auxiliary data from Brest and Santander.
• Reconstructing historical sea level records based on the described data archaeology and correction processes.
• Validating climate models using high-resolution, quality-controlled sea level observations.

Strengths

• Time series extends back to 1875, providing long-term context.
• Includes multiple levels of processed data (L0-L4) for different research needs.
• Complements auxiliary datasets from Brest and Santander for comparative analysis.
• Associated with a published data paper and provides detailed documentation and processing notebooks.

Limitations

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