Pyrite Sun Precursor 16S Amplicon Sequencing Data from Matanuska Glacier Mudflats

Matanuska Glacier mudflats in Alaska were sampled in June 2023 to investigate microbial communities involved in pyrite sun formation. The dataset contains 16S rRNA amplicon sequencing data, likely identifying bacteria involved in sulfur, iron, and carbon cycling. It was authored by Heather Fair and is shared under a CC-BY-4.0 license.

Use Cases

• Profiling microbial community composition based on 16S rRNA sequences from cyanobacterial mats.
• Investigating sulfur cycling based on the presence of bacteria like Thiobacillus and Desulfovibrio.
• Studying iron cycling based on the presence of bacteria like Rhodoferax and Geobacter.
• Correlating microbial taxa with geochemical conditions described in the proposed formation model.

Strengths

• Dataset is focused on a specific, novel geobiological hypothesis about pyrite sun formation.
• Includes data from multiple analyses: 16S sequencing, XRD, and sequential iron extraction as described.
• Released under a permissive CC-BY-4.0 license for reuse.

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 (282.5 KB), indicating a limited scope or preliminary findings.
