CEOS_EXTRA data details mercury speciation in the South Florida aquatic food chain. The dataset contains analytical results for periphyton and water samples collected in 1995 and 1996. Samples were analyzed for total mercury, methylmercury, and nutrient content across three wetland conservation areas.
Use Cases
- Model methylmercury concentration in periphyton based on nitrogen, phosphorus, and organic carbon levels.
- Analyze correlations between water-column major ion concentrations and periphyton mercury speciation.
- Map spatial patterns of mercury contamination across Water Conservation Areas, Big Cypress, and Everglades National Park using sample location and date.
- Investigate temporal trends in total mercury and methylmercury levels between the 1995 and 1996 sampling campaigns.
Strengths
- Data covers multiple sample types (periphyton and water) from the same dates for paired analysis.
- Analytical measurements include speciation between total mercury and the neurotoxin methylmercury.
- Spatial coverage includes three major south Florida wetland conservation areas.
Limitations
- Dataset is temporally stale, with the last update in 1997 and no recent measurements.
- Sample size and row count are unknown, potentially limiting statistical power.
- Geographic scope is limited to specific South Florida wetlands, reducing generalizability.
