Gulf of Mexico oceanographic data collected aboard the OCEAN VERITAS vessel from June 1 to June 5, 2010. The dataset includes chemical, physical, profile, and laboratory analysis measurements such as attenuation/transmission, CDOM fluorescence, volatile organic compounds, and water density. It was gathered by the Subsurface Monitoring Unit, a consortium of government and corporate agencies, in response to the Deepwater Horizon oil spill.
Use Cases
- Analyze Total Petroleum Hydrocarbons (TPH) concentration trends relative to salinity and temperature measurements over the 5-day sampling period.
- Model dissolved oxygen levels using conductivity and hydrostatic pressure data to assess impacts on marine life.
- Correlate CDOM fluorescence and Semivolatile Organic Compounds data to track the spatial distribution of oil-derived contaminants.
- Validate sound velocity and water density profiles collected by CTD instruments against theoretical oceanographic models.
- Use provisional analytical chemistry data from laboratory analysis of water samples for preliminary impact assessment.
Strengths
- Data collected over a focused 5-day period immediately following a major environmental event.
- Includes multiple measurement types: chemical, physical, profile, and laboratory analysis from various instruments.
- CTD data underwent preliminary quality assurance and control procedures at the National Coastal Data Development Center.
Limitations
- Analytical chemistry data are labeled as provisional, indicating potential unreviewed or unvalidated results.
- Sample size and geographic coverage are limited to one vessel cruise over 5 days in a specific region.
- No information on row count, column count, or data completeness is provided.
