Oceanographic CTD Profiles from Deepwater Horizon Oil Spill Response

Nine oceanographic parameters were collected aboard the SEWARD JOHNSON from July 10-14, 2010, in direct response to the Deepwater Horizon disaster. The Subsurface Monitoring Unit, a multi-agency group, gathered this data using CTD, fluorometer, and oxygen meter instruments. Quality assurance and control procedures were applied by the National Coastal Data Development Center to validate scientific integrity.

Use Cases

• Analyzing the vertical distribution of salinity and temperature to map water mass structure in the spill area.
• Correlating CDOM fluorescence and dissolved oxygen measurements to assess hydrocarbon dispersion and biological effects.
• Modeling sound velocity and water density profiles for acoustic and hydrodynamic simulations post-spill.
• Tracking changes in conductivity and hydrostatic pressure to understand subsurface plume dynamics.

Strengths

• Data collection targeted a specific major environmental event, the Deepwater Horizon spill, providing focused context.
• Quality assurance and control procedures were explicitly applied by the National Coastal Data Development Center.
• Measurements cover nine specific parameters including CDOM fluorescence, dissolved oxygen, salinity, and temperature.

Limitations

• Exact row count, file size, and complete column names are not provided by any source.
• Sources conflict on the last updated date, with one listing 2010-07-14 and another 2026-03 05.
• License information is not specified across all platforms.
