Source data for manuscript "Synechococcus dominates the sedimentary record of exported pic

Sijun Huang's dataset supports the manuscript 'Synechococcus dominates the sedimentary record of exported picocyanobacteria in the ocean'. It includes supplementary data on picocyanobacterial abundance, community structure, and alpha-diversity from water-column profiles and sediment cores across the South China Sea and Indian Ocean. The data was last updated on April 28, 2026.

Use Cases

• Quantifying lineage-specific export and preservation of picocyanobacteria based on qPCR and flow cytometry data.
• Analyzing community structure shifts between water columns and sediments using Amplicon Sequence Variant (ASV) tables.
• Estimating carbon sequestration potential by comparing Synechococcus and Prochlorococcus contributions mentioned in the description.
• Calculating decomposition rates of exported cells in surface sediments based on abundance measurements.

Strengths

• Includes data from five distinct research cruises, providing spatial coverage.
• Contains multiple data types: qPCR abundance, flow cytometry counts, ASV tables, and alpha-diversity indexes.
• Reports specific abundance measurements, such as roughly 10–100 cells mL⁻¹ in deep waters and up to 100,000 cells g⁻¹ in surface sediments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the South China Sea and Indian Ocean sampling locations.
