Method P.16213 right column 2nd paragraph: "[Researchers] compiled [their] cell counts from the South Pacific Gyre (ref 5), the North Pacific Gyre, and the eastern equatorial Pacific Ocean with previously published counts from ocean margins and the equatorial Pacific Ocean (Fig. 1B)."
Comments P.16216 left column bottom paragraph: "Based on [researchers'] estimates of total subseafloor sedimentary cell abundance and cellular carbon content, their calculation of subseafloor microbial biomass amounts to 4.1petagram (Pg), with minimum and maximum estimates of 1.5–22PgC, respectively."
