Archaeal Community Structure in Hydrothermal Sediments of the Northwest Indian Ocean

This dataset contains 16S rRNA gene amplicon sequencing data from sediment cores collected from two contrasting hydrothermal sites in the Tianxi u vent field. Comparative analysis reveals distinct archaeal community composition, co-occurrence networks, and inferred metabolic potentials between near-vent and far-vent sediments, identifying geochemical gradients as a key driver.

Use Cases

• Analyze archaeal community shifts along hydrothermal gradients
• Compare co-occurrence network complexity between sites
• Correlate taxon abundance (e.g., Hydrother marchaeia) with geochemical variables
• Infer metabolic pathways from taxon associations

Strengths

• High-resolution archaeal community data from contrasting hydrothermal settings
• Paired with metagenomic analysis for functional insights (BC12)
• Explicit correlation with measured geochemical gradients

Limitations

• Sample-level metadata (e.g., exact depth, coordinates) not provided in the description
• Data accessibility requires download from figshare
• Row count (sample size) unknown
