Nutrients
The results of nutrient sampling are shown on Figs. 5 & 6. Figure 5 presents the results of surface water ammonium and phosphorus concentrations, Fig. 6 shows mean sediment ammonium and phosphorus concentrations. Results of salinity measurements for the above noted sample sites are shown on Fig. 7. In general, phosphorus in the surface waters was highest in the unrestricted marsh, while ammonium was higher in the restricted marsh. Although these trends were similar between surface waters and sediments, they tended to be more pronounced in the surface waters.


Figure 5. Surface water nutrient concentrations for phosphorus and ammonium. Mouth refers to mouth of Sybil Creek near the Branford Harbor. Transects #1 & #2 in the restricted marsh refer to Transects #3 & #4 used in this report.
Figure 6. Sediment nutrient concentrations for phosphorus and ammonium. Sampling conducted along Transects #1 & #3.
Figure 7. Mean salinity (ssu) + 1 SE for S. patens (SP), Panne (PN), P. australis (PA), and S. alterniflora (SA) habitats in the unrestricted and restricted marshes during the study period. * denotes habitat is significantly different from other habitats in same marsh (p < 0.00001). Habitats crossed by bar are significantly different (p < 0.00001).
