Two versions of helicopter electromagnetic data were flown over a portion of Everglades National Park and surrounding areas in south Florida from December 9-14, 1994. The data were collected by the CEOS_EXTRA organization to map the freshwater-saltwater interface and support groundwater modeling. This project aimed to monitor changes in water quality and test restoration strategies for the region.
Use Cases
- Mapping the freshwater-saltwater interface location using corrected electromagnetic measurements.
- Creating groundwater models by interpreting subsurface conductivity anomalies from the survey data.
- Monitoring synoptic changes in coastal water quality linked to management practices via time-series geophysical evidence.
- Searching for subsurface discharge points into Florida Bay using the spatial electromagnetic data.
Strengths
- Data collection occurred over a 6-day period in December 1994, providing a focused temporal snapshot.
- Two data versions (original and corrected) are provided, allowing for quality assessment and comparison.
Limitations
- The dataset is from a single survey in 1994, making it temporally stale for current hydrological conditions.
- The specific row count, column details, and spatial resolution are unknown, limiting reproducibility analysis.
