CTD Water Column Measurements from Gulf of Mexico Oil Spill Response Cruise

NRDA-processed CTD data from the R/V Seward Johnson Cruise 1 Leg 4 provides conductivity, temperature, depth, dissolved oxygen, and fluorometry measurements. The dataset captures water column parameters collected from August 4 to August 8, 2010, as part of the Deepwater Horizon oil spill sampling effort. NOAA_NCEI is the authoritative source, and the final product is a series of processed and quality-checked NetCDF files.

Use Cases

• Analyze vertical profiles of temperature and salinity (conductivity) to study water column stratification.
• Correlate dissolved oxygen measurements with fluorometry data to assess potential impacts on marine ecosystems.
• Map the spatial distribution of physical parameters (depth, temperature) across the Gulf of Mexico cruise track.
• Use the time-series of CTD casts to track changes in water properties during the immediate oil spill response period.

Strengths

• Data has been processed and quality checked, indicating a level of reliability.
• Provides multi-parameter measurements (temperature, conductivity, depth, dissolved oxygen, fluorometry) per cast.

Limitations

• The temporal coverage is limited to a 5-day cruise in August 2010.
• Specific row counts, column details, and sample sizes are unknown.
• Data is over 14 years old, limiting analysis of current conditions.
