Spatial gradients of polychlorinated biphenyls (PCBs) and organochlorine pesticides were examined in young-of-the-year bluefish. The data was collected in the vicinity of a PCB Superfund Site in New Bedford Harbor, Massachusetts, and adjacent waters by the National Oceanic and Atmospheric Administration. The dataset was last updated on the platform in March 2026.
Use Cases
- Model spatial contaminant gradients based on sampling locations near a Superfund site.
- Analyze bioaccumulation patterns of PCBs and pesticides in a specific fish species (young-of-the-year bluefish).
- Assess environmental remediation impacts by comparing contaminant levels in harbor and adjacent waters.
Strengths
- Data focuses on a specific, ecologically relevant species (young-of-the-year bluefish).
- Examines multiple contaminant classes (PCBs and organochlorine pesticides).
- Spatial context is clearly defined around a known PCB Superfund Site.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the single study area.
