The Daya Bay metagenomic and metatranscriptomic dataset

An hourly time-series dataset of planktonic microbial and viral communities from subtropical Daya Bay, collected over three days. The 4.2 GB dataset, authored by songze Chen and last updated in May 2026, includes metagenomic, metatranscriptomic, and viromic sequencing results. It captures fine-scale temporal variations in genomic composition and transcriptional activity.

Use Cases

• Analyzing diel cycles in microbial community composition based on the hourly sampling resolution.
• Investigating metabolic potential and transcriptional activity shifts based on the paired metagenomic and metatranscriptomic data.
• Studying host-virus interactions in marine ecosystems based on the inclusion of viromic sequencing for the viral fraction.
• Modeling fine-scale temporal dynamics of planktonic assemblages based on the two-hour interval sampling over three days.

Strengths

• High temporal resolution with samples collected at two-hour intervals over three days.
• Multimodal sequencing approach covering metagenomics, metatranscriptomics, and viromics.
• Dataset size of 4.2 GB suggests substantial sequencing depth.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects a specific geographic (Daya Bay) and short temporal (three-day) context.
