Vertical profiles of relative abundance of Bacteria, Archaea, and Eukarya to total SSU rRNA in the water column (A and B) and sediment (C and D) in March 2003 (A and C) and June 2003 (B and D). The total SSU-rRNA amount was calculated by totaling the signals of three domain-specific probes. Horizontal bars indicate maximum and minimum ratios of specific probes to total SSU rRNA.
