NOAA NCEI Accession 0069103 contains chemical, physical, profile, and laboratory analysis data collected aboard the OCEAN VERITAS vessel in the Gulf of Mexico from August 6 to August 10, 2010. The Subsurface Monitoring Unit gathered data on attenuation/transmission, CDOM fluorescence, volatile and semivolatile organic compounds, total petroleum hydrocarbons, conductivity, dissolved oxygen, salinity, temperature, and water density using CTD, LISST, transmissometer, fluorometer, and oxygen meter instruments. This dataset was created in response to the Deepwater Horizon oil spill event.
Use Cases
- Analyze Total Petroleum Hydrocarbons (TPH) and Volatile Organic Compounds concentrations to assess post-spill contamination levels.
- Correlate CDOM fluorescence and attenuation/transmission measurements with suspended solids data to map plume dispersion.
- Model water density and salinity profiles from CTD data against hydrostatic pressure and temperature readings.
- Track dissolved oxygen levels alongside conductivity to evaluate impacts on marine ecosystem health.
Strengths
- Data collected over a focused 5-day period during a major environmental event.
- Includes multiple measurement types: chemical, physical, profile, and laboratory analysis.
- Preliminary quality assurance and control procedures were applied to CTD data by the National Coastal Data Development Center.
Limitations
- Analytical chemistry data are provisional and from onshore laboratory analysis.
- Sample size and row count are unknown, limiting statistical confidence.
- Temporal coverage is very short, capturing only a snapshot from August 2010.
