The fluctuations of aerobic, heterotrophic bacteria, particulate organic carbon (POC), and adenosine triphosphate (ATP) in the water system of a salt marsh were investigated at two marsh creeks. Both reached maximum densities of bacteria just before low tide. In a typical study, however, the mean concentration at station 1 over a tidal cycle was an order of magnitude greater than at station 2. POC increased twofold to fourfold during ebbtide in both systems. ATP concentrations at station 2, during ebbtide, increased about fourfold, and the fraction of the total carbon regarded as “living” ranged from 2–24%.
