Figure 3. Depth distribution of total bacteria (solid circles) and dividing cells (open squares) to ~565 mbsf at Site 1027. The dashed line represents a general regression line of bacterial numbers vs. depth in deep-sea sediments (Parkes et al., 1994). The bold vertical dashed line at log10 5.3 is the calculated detection limit. Horizontal bars on the total bacterial data points are 95% confidence limits.

The dashed line represents a general regression line of bacterial numbers vs. depth in deep-sea sediments (Parkes et al., 1994). The bold vertical dashed line at log₁₀ 5.3 is the calculated detection limit. Horizontal bars on the total bacterial data points are 95% confidence limits.
