  1. 1st International Conference on Mining Impacts to the Human and Natural EnvironmentsThe use of Seismic Profiling to identify subsurface fluid migration pathwaysJames Flocks

  2. U.S. Geological Survey

  3. Principles of karst

  4. Principles of karst Soil-filled sinkhole Dissolution fractures

  5. High Resolution Seismic Profiling (HRSP)

  6. 35 water bodies within the SJRWMD Seismic profile projects in Florida

  7. Seafloor Vent Buried sinkhole Freshwater plume Seafloor Spring vent Buried sinkhole Seismic profile projects in Florida - Marine

  8. Seismic profile projects in Florida - Lakes

  9. Seismic profile projects in Florida - Rivers http://coastal.er.usgs.gov

  10. Undiff. Sand and Clay Hawthorn Group Ocala Limestone Groundtruthing seismic profiles Drill wells

  11. Ocala Karst after overburden removal Peace River draining underground Winter Park sinkhole, leaky pool drain Applications to environmental monitoring 1. Alteration of the landscape impacts drainage 2. Much of the drainage occurs in the subsurface 3. Altered drainage can increase dissolution of the underlying geology

  12. Applications to environmental monitoring 1. Alteration of the landscape impacts drainage 2. Much of the drainage occurs in the subsurface 3. Altered drainage can increase dissolution of the underlying geology 4. Subsurface dissolution pathways can be detected using seismic profiling, and ground- truth using invasive methods
