Main IdeasAnatomy of a spillMajor oil spills ConsequencesWildlife damageClean up/ Prevention
What is an oil spill? the release of a
liquid petroleum hydrocarbon into the environment
Mostly marine Human activity
Petroleum seeps Fractures, fissures,
outcrops
Exxon Valdez 1989 Tanker ran aground on Bligh Reef – Alaska 10.9 million gallons of 53 mil release in 3 hrs. 8 of 11 tanks damaged Major storm march 26
Hurricane Katrina> 100 oil
platforms destroyed
4 medium spills134 minor spillsLargest – Bass
Enterprises
Deepwater Horizon Exploded drilling rig – April 20, 2010
Methane gas 11 dead
Lasted 3 months 4.9 mil BBLs
210 mil gallons leaked Capped July 15 Contaminated 16,000 mi. of coastline
Deepwater Horizon
Wildlife Damages Animals may not avoid oil spills Oil coats animal’s bodies Oil that sticks to feathers and fur
causes: Hypothermia Decreased Buoyancy Increased predation Malnutrition Damage scent Internal health problems
Hypothermia Destroys insulation and waterproof
features Lanugo – wooly fur insulation
Buoyancy Oiled feathers at weight
Drowning of birds Fur seal pups
Unable to stay afloat with oiled fins
Increased Predation Inability to fight off predators
Matted feathers Oiled flippers
Causes low body temperature Metabolism tries to combat cold, body
weight diminishes Prey contamination
Malnutrition
Damage Scent Covers scent of
seal pups Rejection Abandonment Starvation
Internal Health Ingestion causes ulcersStomach bleedingInflammation and infection

Prevention Offshore Oil Spill Prevention and
Response Reassessing training protocols, equipment
and procedures Plans for avoidance, control and shutdown
of offshore operations Federally mandated Drilling blowout preventer
Pipe rams and Shear rams
Expected Learning Outcomes What is an oil spill? What are 2 ways it affects wildlife? How can oil be cleaned from land? What is a BOP?
