1997 sediment and water quality data from the Delaware Bay estuary system, collected from September 2 to October 8. The dataset was created by NOAA's National Centers for Environmental Information (NCEI) using a stratified probabilistic sampling design based on the Sediment Quality Triad approach. It characterizes chemical contamination, sediment toxicity, and benthic infaunal community structure from the fall line to the mouth of the Bay.
Use Cases
- Analyze correlations between chemical contamination measurements and sediment toxicity bioassay results (Microtox, amphipod, sea urchin gamete).
- Model benthic infaunal community structure as a function of sediment quality and contaminant levels.
- Map the spatial distribution of toxicity and biological effects from the fall line to the mouth of Delaware Bay using georeferenced samples.
- Assess the extent and magnitude of biological effects associated with specific contaminants identified in the study.
Strengths
- Data collection follows the structured Sediment Quality Triad (SQT) methodology.
- Sampling utilized a stratified probabilistic design for system characterization.
- Covers a defined temporal period from 1997-09-02 to 1997-10-08.
Limitations
- Dataset is from a single sampling period in 1997, limiting temporal trend analysis.
- Specific row count, column names, and sample sizes are unknown.
- Data may be geographically limited to the Delaware Bay estuary and adjacent waters.
