Processed CTD Data from Deepwater Horizon Oil Spill Response Cruise

NetCDF files contain processed Conductivity, Temperature, and Depth (CTD) casts from the M/V Sarah Bordelon Cruise 07. Measurements include temperature, conductivity/salinity, depth, dissolved oxygen, and fluorometry to determine physical oceanographic parameters. Data was collected and quality-checked by the National Oceanic and Atmospheric Administration as part of the Deepwater Horizon oil spill Natural Resource Damage Assessment.

Use Cases

• Analyzing vertical profiles of temperature and salinity to understand water column structure in the Mississippi Canyon area.
• Correlating fluorometry data with other samples to assess phytoplankton response to the oil spill event.
• Using dissolved oxygen and conductivity measurements to model changes in water quality following the spill.
• Mapping the spatial distribution of sea water density anomalies from the collected CTD casts.

Strengths

• Data has been processed and quality-checked, as stated in all source descriptions.
• Contains multiple key oceanographic parameters: temperature, conductivity, depth, dissolved oxygen, and fluorometry.
• Time range is precisely documented from 2010-12-04 to 2010-12-19.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• A conflict exists on the 'last updated' metadata, with one source listing 2010-12-19 and another listing 2026-03 05.
