Harbor seals in the Gulf of Maine show high tissue levels of PCBs, dioxins, mercury, and other industrial pollutants. The data originates from the Seals as Sentinels study conducted by the organization MERI, led by Dr. Shaw. Findings are intended to explain implications for human health and the ocean environment.
Use Cases
- Analyze bioaccumulation trends of PCBs and dioxins based on seal tissue measurements.
- Assess mercury contamination levels in marine mammals based on tissue data.
- Model pollutant transfer implications for human health based on the sentinel species findings.
- Monitor industrial pollutant impacts on the Gulf of Maine ecosystem based on seal tissue levels.
Strengths
- Focuses on a recognized sentinel species for environmental monitoring.
- Includes measurements for specific pollutants: PCBs, dioxins, and mercury.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
Provenance
- Source
- MERI (Marine Environmental Research Institute) via NASA Earthdata platform.
- Collection Method
- Likely contains biological sampling and tissue analysis from the ongoing Seals as Sentinels study.
- Time Range
- null
- Freshness
- unknown
- Geography
- Gulf of Maine
