Description
Chemical and physical oceanographic profile data were collected aboard the Specialty Diver I in the Gulf of Mexico from 2010-09-10 to 2010-09-15 in response to the Deepwater Horizon oil spill event. The dataset includes conductivity, dissolved oxygen, fluorescence, hydrostatic pressure, salinity, sound velocity, temperature, and water density, collected using CTD, fluorometer, and oxygen meter instruments. Data underwent quality assurance and control procedures at the National Coastal Data Development Center.
Use Cases
Tracking subsurface oil plume dispersion based on fluorescence and dissolved oxygen measurements.
Modeling changes in water column structure (density, salinity, temperature) following a major hydrocarbon release.
Calibrating hydrodynamic models with in-situ sound velocity and pressure data from the spill zone.
Assessing potential impacts on marine ecosystems using chemical and physical profile data.
Strengths
Data collection was part of a coordinated multi-agency (Subsurface Monitoring Unit) response to a major environmental event.
Underwent documented quality assurance and control procedures at a national data center (National Coastal Data Development Center).
Covers a specific, critical 6-day period (2010-09-10 to 2010-09-15) shortly after the Deepwater Horizon spill.
Limitations
Key metadata such as row count, file size, and specific column names are not provided on any platform.
The dataset's spatial coverage is limited to the cruise track of a single vessel (Specialty Diver I).
Provenance
Source
Subsurface Monitoring Unit (SMU), consisting of multiple government and corporate agencies, collected aboard the Specialty Diver I.
