Sediment samples from multiple Puget Sound locations contain biological and chemical measurements of bioeffects associated with toxicants. Data includes amphipod survival rates, infauna taxon counts, urchin fertilization rates, Microtox and Cytochrome toxin results, and sediment size fractions. The dataset was collected by NOAA's National Status and Trends Program from 31 May to 30 June 1999.
Use Cases
- Correlate sediment size fractions with amphipod survival rates to assess habitat quality impacts.
- Model urchin fertilization rates against Microtox and Cytochrome toxin results to identify chemical stressors.
- Analyze spatial patterns of infauna taxon counts to map biological community health across Puget Sound.
- Use amphipod survival and urchin fertilization rates as bioindicators for integrated sediment quality assessment.
Strengths
- Data collected under NOAA's standardized National Status and Trends Program
- Includes multiple biological endpoints (survival, fertilization, taxon counts) and chemical assays
- Spatially explicit samples from multiple locations in Puget Sound
Limitations
- Single-month temporal snapshot from 1999, limiting trend analysis
- Unknown sample size (row count) and specific number of locations
- Lacks modern contaminant measurements or genetic biomarkers
