Delaware Estuarine Water Quality Monitoring Data from 1995

July-December 1995 water quality data from two Delaware Bay estuarine reserves, the St. Jones River and Blackbird Creek. Measurements of parameters like water temperature, salinity, and dissolved oxygen were taken every 30 minutes at two specific sites over two-week periods. The dataset was produced by the Delaware National Estuarine Research Reserve, with the latest documented update in August 1997.

Use Cases

• Analyze temporal patterns in water temperature, specific conductivity, and salinity from 30-minute interval data.
• Compare dissolved oxygen concentration and pH levels between the urban-impacted St. Jones River and the less-impacted Blackbird Creek sites.
• Correlate water depth and turbidity measurements with seasonal or tidal influences at the specified geographic coordinates.
• Model the relationship between land use (described as urbanized vs. agricultural/forested) and observed salinity ranges (8-30 ppt vs. 2-7 ppt).

Strengths

• Data collection at a high temporal resolution of every 30 minutes.
• Clear geographic context with precise latitude and longitude coordinates for two distinct sampling sites.
• Explicit documentation of the monitoring period (July-December 1995) and a subsequent update date.

Limitations

• Limited temporal coverage to a single six-month period in 1995, making it unsuitable for analyzing long-term trends.
• Small spatial scope with data from only two specific sites within Delaware.
• Sample size and total row count are unknown from the provided description.
