Gulf of Mexico Research Initiative
$500 million, 10-year investment
Goal - Improve society’s ability to understand, respond to, and mitigate the effects of petroleum pollution and related stressors
Focus areas: 1. How do oil and dispersants move around the
environment?2. How do oil and dispersants break down over time? 3. How do oil and dispersants impact the environment?4. How can technology be improved? 5. How do oil spills impact people?

Understanding fisheries impacts from oil spills: 3 level approach
How do oil spills impact a group of living things of the same species?
How do oil spills impact many different kinds of living things in an area or habitat?
How do oil spills impact individuals?

BUT chemicals in oil can cause: • Decreased swimming speed• Decreased size• Deformities• Sensitivity and impact varies
by fish life stage/age, & concentration of oil
FISH are good at breaking down the bad stuff in oil!• Oil metabolizing gene (CYP1A) triggers
production of proteins that will breakdown PAHs in fish
• Animals without CYP1A bioaccumulate• CYP1A is a biomarker for oil exposure in fish

Did the Deepwater Horizon oil spill cause skin lesions on fish?
• There was an increase in skin lesions on offshore marine fish
• There was an increase in PAHs in locations with lesioned fish during the same time period
• The PAHs found in the lesioned fish were similar to the PAHs in DWH oil samples, but it is not 100% certain that DWH oil caused the lesions

Community Impacts
• Pre-spill normal diet :
– shrimp, crabs, squid but also a 15 – 20% zooplankton
• Post-spill diet shift attributed to DWH
– more fish & crustaceans and less zooplankton

• Deep sea fish are exposed to PAHs in different ways
• Fish habitat and fish behavior play a key role in exposure
• Oiled sediments exposed golden tilefish to higher levels of PAH for a few years after the oil spill
• Episodic exposure; source of PAH not determined
