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)." |

P.16215 right column 2nd paragraph: "Integrating over the world’s ocean area, [researchers] estimate the total
number of cells in subseafloor sediment to be 2.9×10^29 cells. A bootstrap exercise to check [their] analytical solution yielded a median value of 3.3×10^29 cells, with the first SDs at 1.2×10^29 and 8.0×10^29 cells (see SI Text for details)." See Braun et al., 2016, PMID 27630628 p.7 right column top paragraph: "Based on a larger data set that also included very low cell abundances for the large oligotrophic ocean gyres, Kallmeyer et al. (2012) downscaled these numbers to a global inventory of 2.9 × 10^29 cells, corresponding to 0.18–3.6% of total global biomass." See BNID 108500 |
