Microbial Iron Metabolism Genes in Oxic and Hypoxic Estuarine Sediments

Metagenomic data from sediment cores in the Oujiang River and Yangtze River estuaries, comparing microbial iron metabolism under oxic and hypoxic conditions. The dataset, authored by Rui Du and last updated in May 2026, includes genetic potential for iron redox cycling and acquisition systems. It is complemented by geochemical data from a 16-day sediment core incubation experiment.

Use Cases

• Compare taxonomic distribution of iron metabolism genes based on oxic versus hypoxic conditions described in the study.
• Analyze co-occurrence networks linking iron cycling to carbon, nitrogen, sulfur, and phosphorus transformations mentioned in the description.
• Model nutrient release (e.g., phosphate, ammonium) under short-term deoxygenation based on the incubation experiment results.
• Investigate stratification of microbial communities (e.g., Proteobacteria, Chloroflexota) with sediment depth as described for the hypoxic estuary.

Strengths

• Includes data from two distinct estuarine environments (Oujiang River and Yangtze River) for comparative analysis.
• Complements metagenomic data with geochemical measurements from a 16-day incubation experiment.
• Licensed under CC-BY-4.0, permitting broad reuse with attribution.

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 (32.3 KB), indicating limited scope or a summary-level dataset.
