Delaware Bay Water Quality Measurements from Four Estuarine Sites

Delaware Bay water quality data collected at four monitoring sites from January to December 2002. The dataset contains high-frequency measurements of parameters like water temperature, salinity, and dissolved oxygen taken every 30 minutes over two-week periods. It was produced by the SCIOPS organization for the National Estuarine Research Reserve system.

Use Cases

• Modeling salinity or dissolved oxygen concentration from water temperature and specific conductivity using time-series analysis.
• Analyzing trends in pH and turbidity over time to assess water quality changes at Scotton Landing, Lebanon Landing, Division Street, and Blackbird Landing sites.
• Correlating water depth measurements with tidal cycles or seasonal variations across the St. Jones River and Blackbird Creek watersheds.
• Detecting anomalies in percent saturation or specific conductivity data streams collected at 30-minute intervals.

Strengths

• High temporal resolution with measurements recorded every 30 minutes.
• Covers four distinct monitoring sites (Scotton Landing, Blackbird Landing, Lebanon Landing, Division Street) across two watersheds.
• Includes eight core water quality parameters per measurement.

Limitations

• Data is from a single year (2002), limiting analysis of long-term trends.
• Unknown total row count and sample size for statistical reliability.
• Geographic scope is limited to specific sites within Delaware Bay.
