Summary

This study uses electomagnetic (EM) methods to map the location of the saltwater/freshwater interface in the Florida Everglades.

For more information, please see the Tides and Inflows in the Mangrove Ecotone (TIME) Model Development Project Webpage.

This project addresses the question of determining the location of the fresh-water/salt-water interface (FWSWI) in the coastal regions of southern Dade and Monroe Counties, synoptic monitoring of changes in water quality associated with changes in water management practices, and looking for geophysical evidence of subsurface discharges of fresh water to Florida Bay.

This project covers a 1036-square-kilometer region of the Everglades located in Everglades National Park and surrounding areas. The study area is bounded on the east by U.S. Highway 1, on the south by Florida Bay and Whitewater Sound, and on the far west by the mouths of the Harney River and Shark River Slough. From these boundaries the study area extends inland from 14 to 22 km.
