Biomarker Measurements for Soil Carbon Components in the Yellow River Delta Estuary

A multi-biomarker dataset analyzing soil organic carbon components across 0–100 cm soil profiles under four vegetation types along a salinity gradient in the Yellow River Delta Estuary. The dataset, authored by Yu Bingbing and last updated in May 2026, quantifies contributions from plant-derived carbon, microbial necromass carbon, and glomalin-related soil protein. It provides insights into carbon stabilization mechanisms under sea-level rise scenarios.

Use Cases

• Modeling carbon accumulation vulnerability based on biomarker contributions mentioned in the description.
• Analyzing relationships between soil nutrients, geochemical properties, and carbon component fractions.
• Investigating the role of glomalin as an iron carrier in mineral-associated carbon stabilization.
• Assessing the impact of electrical conductivity and pH on plant-derived and microbial carbon pools.

Strengths

• Data covers soil profiles from 0 to 100 cm depth, providing vertical distribution information.
• Analysis includes four distinct vegetation types along a salinity gradient.
• Employs a multi-biomarker approach (lignin, amino sugars, glomalin) for detailed carbon component quantification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (56.6 KB), indicating a limited scope or sample size.
