Figure F6. Total prokaryotic cells (solid circles) and the percentage of those cell numbers involved in cell division (open circles) with depth at Site 1231. Both total cell counts and dividing cell percentages become increasingly unreliable as total cell counts decrease below 4 x 106 cells/cm3 as within-sample variability rises due to the low number of cells counted. Vertical dashed line on the left represents the significance limit at 4 x 105 cells/cm3.

Both total cell counts and dividing cell percentages become increasingly unreliable as total cell counts decrease below 4 x 10⁶ cells/cm³ as within-sample variability rises due to the low number of cells counted. Vertical dashed line on the left represents the significance limit at 4 x 10⁵ cells/cm³.
