Description
Oceanographic data includes CDOM fluorescence, Semivolatile Organic Compounds, Total Petroleum Hydrocarbons, Volatile Organic Compounds, conductivity, dissolved oxygen, hydrostatic pressure, salinity, sound velocity, temperature, and water density. The Subsurface Monitoring Unit collected this data aboard the Ferrel vessel from August 3 to August 11, 2010, in response to the Deepwater Horizon oil spill. Provisional analytical chemistry results and CTD data underwent preliminary quality control.
Use Cases
Analyze Total Petroleum Hydrocarbons (TPH) concentration trends against salinity and temperature profiles to model oil plume behavior.
Correlate Volatile Organic Compounds data with dissolved oxygen measurements to assess microbial degradation activity.
Use CDOM fluorescence and conductivity readings to track the dispersion of dissolved organic matter from the spill site.
Model water density and sound velocity from CTD profiles to understand changes in water column structure post-spill.
Assess provisional Semivolatile Organic Compounds laboratory results against in-situ hydrostatic pressure data for depth-related contamination analysis.
Strengths
Data covers a specific 9-day sampling period during a major environmental event.
Includes multiple data types: in-situ CTD profiles and provisional onshore laboratory analysis.
Collection involved a coordinated multi-agency unit (Subsurface Monitoring Unit).
Limitations
Analytical chemistry data are labeled as provisional, indicating potential unverified results.
Sample size and row count are unknown, limiting statistical certainty.
Temporal coverage is limited to a single, short cruise in August 2010.
