CTD Oceanographic Data from the Deepwater Horizon Oil Spill Response

Gulf of Mexico conductivity, temperature, and depth data were collected from the R/V HOS Davis over one week in November 2010. The dataset contains processed measurements for physical oceanographic parameters, including dissolved oxygen and fluorometry. It was created by NOAA's National Centers for Environmental Information as part of the Deepwater Horizon oil spill sampling effort.

Use Cases

• Analyze temperature and salinity profiles from CTD casts to model water mass structure in the spill area.
• Correlate fluorometry data with other spill indicators to track dissolved hydrocarbon plumes.
• Use dissolved oxygen measurements alongside depth data to assess potential impacts on marine biogeochemistry.
• Map the spatial distribution of collected CTD casts to visualize sampling coverage during the response cruise.

Strengths

• Data is processed and quality-checked, as stated in the description.
• Covers a specific, critical event (Deepwater Horizon spill) with temporal precision (2010-11-07 to 2010-11-14).
• Includes multiple oceanographic parameters (temperature, conductivity, depth, dissolved oxygen, fluorometry).

Limitations

• Sample size and row count are unknown.
• Data is from a single, one-week cruise, limiting temporal scope.
• Geographic coverage is specific to the cruise track in the Gulf of Mexico.
