Monthly Bacterial Community Data from Tongoy Bay Upwelling System

Monthly seawater samples collected over one year at 9 m depth in Tongoy Bay, a coastal upwelling area in the southeastern Pacific. The dataset, authored by Omar Arzola, uses high-throughput 16S rDNA sequencing to characterize free-living and particle-associated bacterial communities across physicochemical gradients and upwelling intensity.

Use Cases

• Analyze bacterial community shifts based on upwelling intensity and lifestyle (free-living vs. particle-associated) mentioned in the description
• Predict functional potential of microbial communities based on taxonomic composition and environmental gradients described
• Identify potential pathogen indicators (e.g., Vibrio species) based on their association with intense upwelling events described
• Study niche specialization in biogeochemical cycling (e.g., carbon degradation, sulfur cycling, photoautotrophy) based on functional pathway enrichments described

Strengths

• Data spans a full year of monthly sampling, capturing seasonal and intra-seasonal variability
• Includes paired analysis of free-living and particle-associated bacterial fractions, enabling lifestyle-specific comparisons
• Licensed under CC-BY-4.0, permitting open sharing and adaptation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is contained within a PDF file (1.1 MB), which may require extraction and structuring for analysis
