Transects across three major creeks joining the North Inlet marsh system to the neighboring ocean and bay environments were characterized in terms of the temporal fluctuations, distribution, and short-term transport of total microbial biomass (measured as adenosine 5′-triphosphate [ATP]). The mean ATP density ranged from 0.865 to 1.357 mg per m3. Highest densities were recovered during flood tides. The distribution of mean ATP densities as well as net flux through each interface proved to be complex with both vertical and horizontal stratification apparent at some locations. A net import of ATP at a rate of about 40 mg per s was noted at the two creeks that interfaced directly with the oceanic environment. A net export was noted through the creek that emptied into the bay. The results indicate that the characterization of a tidal creek interface in terms of ATP, or similar parameters, requires the simultaneous measurement of both the component of interest and directional velocity.
