CEOS_EXTRA provides dissolved organic carbon (DOC) and specific ultraviolet absorbance (SUVA) data for surface water and pore water in South Florida Water Management District conservation areas. This dataset supports research on mercury interactions with organic matter, collected as part of a multi-agency field and laboratory study. The data was last updated in June 1998.
Use Cases
- Analyze relationships between surface water DOC concentration and SUVA values to characterize organic matter.
- Compare pore water DOC levels with surface water measurements to study vertical biogeochemical gradients.
- Model mercury reactivity and methylmercury formation using DOC chemistry and structural characteristics as features.
- Investigate spatial patterns of water chemistry across selected onsite research locations in the Water Conservation Areas.
Strengths
- Data originates from an intensive, multi-agency study organized by the South Florida Water Management District, U.S. EPA, and USGS.
- Focuses on a specific, poorly understood process (mercury-DOC interactions) critical for modeling mercury behavior.
Limitations
- Dataset is temporally stale, with last update in 1998, limiting relevance to current conditions.
- Sample size, row count, and specific geographic coordinates are unknown, hindering reproducibility.
Provenance
- Source
- CEOS_EXTRA, via NASA Earthdata.
