Nine chemical and physical oceanographic parameters were collected from CTD casts aboard the SEWARD JOHNSON in the North Atlantic Ocean and Gulf of Mexico. Data were gathered from August 4 to August 8, 2010, by the multi-agency Subsurface Monitoring Unit in response to the Deepwater Horizon oil spill. The National Coastal Data Development Center performed quality assurance and control procedures on these data.
Use Cases
- Analyze salinity and temperature profiles to model water column stratification and pollutant transport.
- Correlate CDOM fluorescence and standard fluorescence measurements with subsurface hydrocarbon presence.
- Model dissolved oxygen levels against hydrostatic pressure and water density to assess potential hypoxia.
- Use conductivity and sound velocity data to calibrate or validate regional oceanographic models.
- Establish a pre-dispersant baseline of physical water properties for the affected Gulf of Mexico region.
Strengths
- Data collected during a critical 5-day period immediately following a major environmental event.
- Includes nine validated parameters: CDOM fluorescence, conductivity, dissolved oxygen, fluorescence, hydrostatic pressure, salinity, sound velocity, temperature, and water density.
- Underwent quality assurance and control procedures by the National Coastal Data Development Center.
Limitations
- Temporal coverage is limited to a single 5-day cruise in August 2010, providing only a snapshot.
- Spatial coverage is restricted to the specific cruise track in the North Atlantic and Gulf of Mexico.
- The dataset's size, row count, and specific sampling resolution are unknown.
