Description
Gulf of Mexico oceanographic profile data were collected aboard the American Diver on August 4, 2010, in direct response to the Deepwater Horizon oil spill. The dataset includes measurements of CDOM fluorescence, conductivity, dissolved oxygen, pressure, salinity, sound velocity, temperature, and water density. Data were gathered by a multi-agency Subsurface Monitoring Unit using CTD, fluorometer, and oxygen meter instruments and have undergone quality assurance by the National Coastal Data Development Center.
Use Cases
Analyzing the vertical distribution of dissolved oxygen and salinity to assess water column stratification post-spill.
Correlating CDOM fluorescence measurements with potential hydrocarbon dispersion from the spill site.
Modeling water density and sound velocity profiles for oceanographic and acoustic studies in the Mississippi Canyon region.
Investigating the relationship between hydrostatic pressure, temperature, and conductivity to validate instrument performance during emergency monitoring.
Strengths
Data collection was performed by a coordinated multi-agency Subsurface Monitoring Unit (SMU), ensuring standardized methodology.
The dataset has undergone formal quality assurance and control procedures at the National Coastal Data Development Center.
Measurements were taken in direct response to a major environmental event, providing a focused temporal snapshot.
Limitations
The dataset appears to contain only a single day of measurements (2010-08-04), limiting temporal analysis.
Conflicting 'last updated' dates exist across platforms (2026-03 06 vs. 2010-08-04), casting doubt on metadata maintenance.
Specific row counts, file sizes, and a complete column list are not provided by any source.
