Abstract: The number of bacteria in sediments, interstitial water and overlying tidal water of an oligohaline marsh system are about 109, 106, and 106 cells cm-3, respectively. Average cell size in the overlying water (about 0•06 µm3), is much smaller than that in sediments and interstitial water (about 0•18 µm3). Most bacterial cells in sediments are bound to sediment particles and less than 1% of the cells were displaced by percolating water through sediment columns. Concentration of bacteria in flooding tidal waters is generally higher than that in ebbing waters. Movement of bacterial biomass does not appear to be a significant mechanism of particulate organic transport in marsh sediments and marsh sediments do not appear to be a source of suspended bacteria for estuaries.
