CTD Measurements from Gulf of Mexico Oil Spill Response Cruise

NRDA-processed CTD data from the Seward Johnson cruise in the Gulf of Mexico provides conductivity, temperature, depth, dissolved oxygen, and fluorometry measurements. The data was collected by NOAA_NCEI from July 10 to July 14, 2010, as part of the Deepwater Horizon oil spill sampling effort. The final product is a series of quality-checked NetCDF files containing every CTD cast.

Use Cases

• Analyze temperature and conductivity profiles to model water column stratification during the spill event.
• Correlate dissolved oxygen and fluorometry data with oil contamination levels in the Gulf of Mexico.
• Map depth-specific measurements to create 3D models of oceanographic parameters around the spill site.
• Use time-series CTD casts to track changes in water properties over the five-day sampling period.

Strengths

• Data is processed and quality-checked according to NRDA standards.
• Covers a specific, critical event (Deepwater Horizon spill) over a defined 5-day period.
• Includes multiple oceanographic parameters (temperature, conductivity, depth, dissolved oxygen, fluorometry).

Limitations

• Sample size and row count are unknown, limiting statistical confidence.
• Temporal coverage is limited to only five days in July 2010.
• Geographic coverage is confined to the cruise track of the Seward Johnson.
