NOAA NCEI Accession 0069356 contains chemical, physical, and sediment analysis data collected aboard the RYAN CHOUEST vessel in the Gulf of Mexico from October 7 to 17, 2010. The Subsurface Monitoring Unit gathered measurements including CDOM fluorescence, Total Organic Carbon, metals, volatile organic compounds, conductivity, salinity, and temperature. Data includes provisional laboratory analysis results and products created for real-time decision support.
Use Cases
- Analyze relationships between Total Petroleum Hydrocarbons (TPH) concentration and sediment properties from core samples.
- Model water column contamination by correlating Volatile Organic Compounds with conductivity, salinity, and temperature CTD profiles.
- Assess organic matter degradation by tracking CDOM fluorescence and dissolved oxygen levels across sampling stations.
- Evaluate spatial distribution of metals and Semivolatile Organic Compounds in sediment cores against hydrostatic pressure and water density.
- Use GIS-formatted data files to map chemical plume movement relative to real-time analysis products like charts and graphs.
Strengths
- Data covers a 10-day intensive sampling period immediately following a major environmental event.
- Includes multiple data types: chemical laboratory analysis, physical CTD profiles, imagery, and sediment core records.
- Preliminary quality assurance and control procedures were applied to CTD data by the National Coastal Data Development Center.
Limitations
- Analytical chemistry data are labeled provisional, indicating potential unreviewed or unvalidated results.
- Temporal coverage is limited to a single 10-day cruise, offering a snapshot rather than long-term monitoring.
- Geographic scope is confined to the Gulf of Mexico region near the Deepwater Horizon spill site.
Provenance
- Source
- Subsurface Monitoring Unit (SMU), a multi-agency group, via NOAA National Centers for Environmental Information (NCEI).
- Collection Method
- Data collected via ship-based instruments including CTD, bottle sampler, fluorometer, oxygen meter, and sediment corer, with onshore laboratory analysis.
- Time Range
- 2010-10-07 to 2010-10-17
