Salinity, temperature, pH, Redox, and sulfide concentrations were measured in 4 stations (sampling units) located in adjacent 10 x 10 m plots (in a 20 x 20 m block). Statistical analyses are in progress.

Intertidal soils can be quite heterogeneous because many edaphic characteristics depend on the depositional and erosional patterns and on the influence of plant communities, which add organic matter, cycle nutrients, and modify soil salinity and redox conditions. Inputs from terrestrial runoff generally are considered the major nutrient source that supports mangrove forest development. As a result patches and zones of forest composition result from complex gradients of hydroperiod and soil condition, such as nutrient limitation (e.g., nitrogen and phosphorous and abiotic stressors (salinity and sulfide). We are testing the general hypothesis that reduction in forest structure along the estuarine gradients are associated with soil variation in soil fertility and stressors along major sources of freshwater in Shark River and Taylor Slough. Method Step Description Pore water samples are colllected from stations at different depths using a plastic siphon and syringe (McKee et al 1988). One aliquot of pore water is assayed for salinity using a LavComp Instrument SCT analyzer and a pH using a HANNA H19025 pH meter. A second aliquot of sample is filtered to reduce error associated with suspended sediments; the first 10 ml of each sample is discarded to avoid oxidation. The next 5 ml of sample was immediately added to an equal volume of antioxidant buffer and brought to the labaoratory where it is analyzed for sulfide concentrations with a LAZAR Model IS-156 sulfide sensing electrode (McKee et al. 1988).
