NOAA Ship Gordon Gunter collected chemical, physical, profile, and underway oceanographic data in the Gulf of Mexico from July 8 to July 16, 2010. The Subsurface Monitoring Unit gathered data on conductivity, dissolved oxygen, salinity, temperature, water density, and current speed components using ADCP, CTD, and oxygen meters. This dataset was created for real-time analysis and decision support following the April 20, 2010 Deepwater Horizon event.
Use Cases
- Analyze the distribution of suspended materials using ADCP-derived current speed U and V components.
- Assess changes in water quality by correlating salinity, temperature, and dissolved oxygen measurements over the cruise period.
- Map the vertical profile of hydrostatic pressure and sound velocity to understand water column structure.
- Model pollutant transport by creating detailed maps of ocean current vectors from the ADCP data.
- Evaluate preliminary CTD data quality assurance procedures implemented by the National Coastal Data Development Center.
Strengths
- Data collected over a 9-day period during a critical environmental event.
- Includes multiple instrument types (ADCP, CTD, oxygen meter) measuring distinct physical and chemical features.
- Contains products created for real-time analysis, including charts, graphs, maps, and GIS files.
Limitations
- ADCP data is described as raw and unprocessed.
- Some datasets associated with the instruments are incomplete.
- Limited temporal coverage of only nine days in July 2010.
