Chemical oceanographic data were collected aboard the RYAN CHOUEST in the Gulf of Mexico from July 28 to August 9, 2010, in response to the Deepwater Horizon oil spill. The dataset includes measurements of Total Petroleum Hydrocarbons (TPH) and fluorescence, gathered by the Subsurface Monitoring Unit using instruments like fluorometers and gas chromatographs. It also contains real-time analysis products such as charts, graphs, and maps, along with cruise-level documentation.
Use Cases
- Model subsurface oil plume transport using geospatial TPH and fluorescence measurements.
- Analyze correlations between fluorescence readings and Total Petroleum Hydrocarbon concentrations.
- Assess the spatial extent of hydrocarbon contamination from the Deepwater Horizon event using cruise-track data.
- Validate real-time decision support products like maps and charts created during the response.
Strengths
- Data collected during a critical 13-day period immediately following a major environmental disaster.
- Includes direct chemical measurements (TPH, fluorescence) from specialized instruments like gas chromatographs.
Limitations
- Data is described as raw and provisional, indicating potential unverified quality.
- Temporal coverage is limited to a single two-week cruise in 2010.
- Specific row counts, column details, and sample sizes are unknown.
