Geophysical Studies of the Southwest Florida Coast

The development of ground-water floor models for the southwest coast of Everglades National Park and Big Cypress National Preserve is an essential part of resource management in the area because of the critical importance of water on the ecosystem and the strong interaction of ground- and surface-water flows in the region. Flow models, which will be developed by other projects in this program, are only as good as the data upon which they are based. Critical to their development is information on the location of geologic boundaries and salinity transitions. Due to the inaccessibility of much of this area and low density of drill holes, an alternative approach is needed to obtain this information. Geophysical data combined with information from any existing or future drill holes provides a way of filling this void and insuring the development of ground-water flow models that are of value in resource management.
