Total Petroleum Hydrocarbon and fluorescence measurements were collected over a 3-day cruise in July 2010 aboard the R/V Ryan Chouest. The Subsurface Monitoring Unit, a multi-agency group, gathered this data for real-time analysis following the Deepwater Horizon spill. Instruments included CTD, fluorometer, and gas chromatograph.
Use Cases
- Model Total Petroleum Hydrocarbon (TPH) concentration dispersion using fluorescence and CTD profile data.
- Analyze correlations between physical water properties from CTD sensors and hydrocarbon levels.
- Track provisional hydrocarbon sensor array readings for anomaly detection during the spill response.
- Use cruise-level documentation and products for reconstructing the environmental monitoring timeline.
Strengths
- Data collected over a focused 3-day period (2010-07-11 to 2010-07-13) for a specific event.
- CTD data underwent preliminary QA/QC procedures by the National Coastal Data Development Center.
- Includes raw sensor data and derived products like charts and maps for decision support.
Limitations
- Hydrocarbon Sensor Array data are explicitly noted as raw and provisional.
- Dataset scope is limited to a single, short cruise following the initial spill event.
- Individual data specifics are contained in separate metadata records, requiring additional lookup.
