Water moves across the south Florida landscape in a fashion far different than it did only a century ago. Seasonal, expansive flows of years past have been replaced by managed, periodic discharges from a handful of points along our coasts, often resulting in great salinity fluctuations in coastal waters. One of the principle goals of Everglades restoration is returning more natural hydrologic conditions to receiving bodies of water, such as Florida Bay and Biscayne Bay.

This CESI-funded investigation provides important baseline data for the shallow-water environments of western Biscayne Bay. Researchers surveyed the area using the Shallow Water Positioning System, and documented salinity and temperature patterns via a high-resolution monitoring network. The results of this study provide not only insight into seasonal species composition, distribution, diversity and abundance in this area, but can serve as a touchstone against which to gauge the effects of ongoing restoration efforts.
