- Description:
-
- Abstract:
-
These helicopter electromagnetic data were flown over a portion of Everglades National Park and surrounding areas in south Florida 9-14 December 1994. Two versions of the data are provided: the original dataset and the corrected dataset.
- Purpose:
-
This project addressed the question of determining the location of the fresh-water/salt-water interface (FWSWI) in the coastal regions of southern Miami-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 to Florida Bay.
This project provided basic information needed to create ground-water models and test various restoration strategies and their impact on ground-water quality.

During the interpretation of the datset provided by Dighem, errors in the data became apparent which caused difficulties in obtaining reliable layered-earth inversion models. These errors were traced to problems with calibration and with the bird tow-cable length. Calibration errors were corrected using a procedure described in Deszcz-Pan et al, 1998.

During 9-14 December 1994 a helicopter electromagnetic survey was flown by Dighem, Mississauga, Ontario, Canada, over parts of Everglades National Park and surrounding areas in south Florida. The survey covered 398 square miles (1031 sq. Km) with flightlines totaling 1718 miles (2765 km). The data were collected towards the end of the wet season.
