UNC-Chapel Hill GEOG 491
November 29, 2010

2. Overview
Objective: Perform a risk assessment analysis for active oil platforms in the Gulf of Mexico that incorporates environmental, economic, and human factors.
Environmental factors: Hurricanes, Sea Floor Sediment Type, Species
Economic factors: State Oil Dependency, Industry Impact, Platform Value
Human factors: Safety, Maintenance, Technology

Shoreline Environmental Sensitivity Index (ESI) – Assesses shoreline vulnerability to oil spills on a scale of 1-10.
At-risk species (more variety and oil-specific vulnerability calculation)
Specific habitat impact analysis (Coral, nesting, spawning locations)
