Coastal data from the Gulf of Mexico region includes time-series measurements of ocean currents and concentrations of marine toxic substances. The dataset was submitted by Science Applications, Inc. - Raleigh NC (SAI) in support of the Brine Disposal project. Measurements were collected from October 1977 to April 1979.
Use Cases
- Model brine plume dispersion using current direction, speed, and water temperature time-series data.
- Analyze correlations between pollutant concentrations and environmental conditions like salinity, sea surface temperature, and wave height.
- Study temporal trends in toxic substance levels near discharge sites using CAS registry number-identified chemicals and collection dates.
- Calibrate hydrodynamic models with Eulerian current measurements reported at 10-15 minute intervals from moored instruments.
Strengths
- Data processed to standardized NODC F005 and F144 formats with documented schema.
- Includes multiple environmental parameters: current speed/direction, water temperature, salinity, wind, wave data, and pollutant concentrations.
- Time-series coverage spans approximately 18 months from 1977 to 1979.
Limitations
- Sample size and spatial coverage are unknown, potentially limiting statistical analysis.
- Data is temporally stale, with the last update in April 1979, reflecting historical conditions.
- Specific row counts, file sizes, and data completeness metrics are not provided.
