This section contains methods for the general project. Water quality monitoring at 10 permanent stations from the mainland saltmarshes to Quinby Inlet was started in July 1988. These stations are sampled monthly for bacterial abundance, microbial activity (respiration and incorporation of acetate), dissolved organic carbon (DOC), particulate organic carbon (POC), pH, salinity, oxygen concentration, turbidity, temeprature, and sediment characteristics. Summer results show the greatest bacterial abundance and microbial activity in the mainland marsh creeks with declining abundance and activity with increasing distance from mainland marshes to a minimum in the inlet. Bacterial abundance and microbial activity in the back-barrier island marsh creeks are substantially greater than at non-marsh stations but are significantly less than in the mainland marsh creeks. Our current hypothesis is that the influence of the mainland (greater nutrient input, greater sediment loads, etc.) is responsible for higher microbial abundance and activity in the landward marshes as compared with the island marshes. Continued monitoring will provide more information regarding seasonal fluctuations in microbial processes occuring in the water column.

The variation in a number of microbial parameters associated with the turnover of carbon will be examined in both space and time. 10 stations arranged along a transect beginning in the mainland marshes of the LTER, passing through Hog Island Bay including mid-bay marshes, covering deep open water near Quinby Inlet, and finishing in the island marshes in the Hodges Narrows area will be sampled at approximately monthly intervals. Microbial parameters to be measured in water and sediment at each station include biomass, activity (defined as turnover rate constant for acetate), and productivity (defined by rate of DNA synthesis). These parameters will be correlated with physical-chemical measures including dissolved oxygen, salinity, pH, temperature, turbidity, dissolved and total organic carbon, etc. This study points toward a quantitative description of microbial activity in the aquatic portion of the LTER with special emphasis directed toward the flow of carbon into detritus based food webs.
