Provenance — who produced it, who reused it
Linked to 1 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.
1 further paper cites this accession but reuse could not be confirmed.
Deep data QC

Amplicon survey of marine metagenome via AB 3730xL capillary sequencing (Sanger-legacy platform), generating 883 million reads (276 billion bases) with good quality (96.5% Q20, 90.7% Q30) despite capillary-sequencing technology. Represents a large-scale marine microbial profiling effort; the 52.2% GC and high read count enable robust community composition surveys, though capillary-based amplicon sequencing is computationally distinct from Illumina/NGS workflows. This legacy dataset provides historical baseline for marine microbial communities and demonstrates feasibility of large-scale capillary-based metabarcoding, now superseded by higher-throughput platforms.
The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
