µSudAqua[db]: Georeferenced Aquatic Microbiome Samples from South America

Over 866 georeferenced aquatic microbiome samples from South America with manually revised environmental metadata. Sebastián Metz from the Centre National de la Recherche Scientifique published this data in July 2022. A curated subset of these samples includes high-quality reads, Amplicon Sequence Variants (ASVs), and taxonomic classifications.

Use Cases

• Analyzing microbial community composition based on Amplicon Sequence Variants (ASVs).
• Modeling relationships between environmental factors and microbiome structure based on contextual metadata.
• Conducting biogeographic studies of aquatic bacteria based on georeferenced sample locations.
• Benchmarking bioinformatics pipelines for rRNA amplicon analysis using the provided DADA2-processed subset.

Strengths

• Contains over 866 georeferenced samples, providing spatial context.
• Metadata is manually revised for quality assurance.
• Includes a curated subset (~60% of samples) processed with the DADA2 pipeline for standardized analysis.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
