MarSOC: Tidal Marsh Soil Organic Carbon Data from 29 Countries

A dataset of 17,454 tidal marsh soil organic carbon records compiled from a systematic literature review. It was created by Tania L. Maxwell at the University of Cambridge. The dataset includes metadata and processing scripts for data cleaning and model testing.

Use Cases

• Predict soil organic carbon stocks based on organic matter content using the provided model testing scripts.
• Analyze the global distribution of tidal marsh carbon data across 29 countries.
• Benchmark new carbon estimation models against a systematically compiled dataset.
• Study the relationship between soil organic carbon and other environmental variables likely present in the records.

Strengths

• Contains 17,454 individual soil records.
• Spatial coverage includes data from 29 countries.
• Includes metadata files and reproducible R scripts for data processing and model testing.

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.
