June 25-29, 2010 data includes chemical, physical, profile, and laboratory analysis measurements collected aboard the OCEAN VERITAS in the Gulf of Mexico. The Subsurface Monitoring Unit, a multi-agency group, gathered data on attenuation/transmission, CDOM fluorescence, organic compounds, conductivity, dissolved oxygen, salinity, temperature, and water density using CTD, LISST, transmissometer, fluorometer, and oxygen meter instruments. This collection was created in response to the Deepwater Horizon Oil Spill event.
Use Cases
- Analyze Total Petroleum Hydrocarbons (TPH) and Volatile Organic Compounds concentrations to map hydrocarbon plume dispersion.
- Correlate dissolved oxygen and salinity measurements from CTD profiles with locations of suspended solids.
- Model water density and sound velocity changes using concurrent temperature and conductivity data.
- Assess CDOM fluorescence and attenuation/transmission readings to estimate particulate matter from the spill.
Strengths
- Data collected over a focused 5-day period during a major environmental event.
- Includes provisional laboratory analysis results for water and sediment samples.
- CTD data underwent preliminary quality assurance and control procedures.
Limitations
- Analytical chemistry data are labeled as provisional, indicating potential unverified results.
- Sample size and row count are unknown, limiting statistical assessment.
- Data temporal coverage is limited to a single, short cruise post-spill.
