The transport of microbial biomass and suspended material in a high-marsh creek.
The transport of microbial biomass and suspended material in a high-marsh creek was investigated during four 40-h tidal studies throughout the year. Although considerable differences were noted between successive tidal cycles, overall the creek was found to be an exporting system and transported a mean concentration of ATP (-33g), chlorophyll a (-66g), particulate organic carbon (-31kg), total suspended material (-344kg), and fixed suspended material (-195kg) during each tidal cycle. This net outward flux of materials was associated with a net flow of water out of creek, while the net import of aerobic, heterotrophic bacteria (43 x 10(12)) and volatile suspended material (238kg) was generally due to higher mean concentrations of these materials per unit volume of water during the flooding tide. Also the latter generally were associated with increased amounts of suspended material suggesting an association between bacteria and suspended matter.
