nutrient concentrations along salinity gradient • Results & comparison with proposed targets (Marshall,
Wingard & Pitts, E&C, 2013; and this session)
• Conclusions/Recommendations

• Salinity gradient analysis • Several stations along transects
– Change components, structure and function of ecosystem
• One station under different salinities – Preserve components, structure and function of
ecosystem

General TN decline as salinity increases. Green arrow shows potential trend if restoration is implemented. Blue arrow shows trend as sea level rises.

Positive slopes = above average TN Negative slopes = below average TN Horizontal segments = average TN
If salinity drops below 5 psu due to restoration, TN values would be preferentially above the current mean, in other words SRM would
experience nutrient enrichment
Running sum of standardized concentrations TNcsum=(TN-TNave)/TNsd

Conclusions: - Increased freshwater flows into the coastal
Everglades will cause changes in water quality besides the intended declines in salinity
- Time series analysis indicate that in Florida Bay TN, TP and CHLa concentrations may increase
- In 10,000 Islands-Whitewater Bay, TN may increase everywhere; TP may decline in fresher water stations (landward) with no clear pattern oceanward; CHLa may increase except in freshwater end members around Shark River mouth.
