What this means

claude:haiku

Seawater metagenome amplicon sequencing via Illumina MiSeq with 31.3 million reads and 13.8 billion bases at excellent quality (98.1% Q20, 95.9% Q30). The balanced 50.7% GC and large sequencing volume enable comprehensive marine microbial community profiling. This dataset is suitable for oceanographic and temporal sampling studies addressing phytoplankton-bacteria co-occurrence and nutrient cycling.

How this grade was computed

Weighted mean of 2 scored metric(s) → 100/100

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.
