Figure F8. Total prokaryotic cells (solid circles) and the percentage of dividing cells (open circles) with depth at Site 1229. Dividing cell percentages become increasingly unreliable as total cell counts decrease below 1 x 107 cm-3 as within-sample variability rises due to the low number of cells counted. Vertical dashed line on the left represents the detection limit at 5.8 x 105 cells/cm3.

Figure F8. Total prokaryotic cells (solid circles) and the percentage of dividing cells (open circles) with depth at Site 1229. Dividing cell percentages become increasingly unreliable as total cell counts decrease below 1 x 10⁷ cm^-3 as within-sample variability rises due to the low number of cells counted. Vertical dashed line on the left represents the detection limit at 5.8 x 10⁵ cells/cm³.
