Fig. 2: Depth-resolved abundance of Arctic diazotroph MAGs across the global oceans.

The abundance data are divided into three size fractions and three depths. Total, bacterial, and viral fractions indicate ≥0.2, 0.2–3, and <0.2 µm filter size fractions used for sample collection, respectively. Sampled depths are divided into ≤200, 200–1000, and ≥1000 m, and are indicated in red, black open circle, and blue, respectively. The genome abundance was calculated as a length-normalized count per million microbe genomes of a total community (CPMM) in each fraction. The area of each circle is proportional to its indicated abundance. The plus signs indicate the location with CPMM lower than 1.
