  4. 4. 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
  5. 5. Hurricane Katrina > 100 oil platforms destroyed  4 medium spills 134 minor spills Largest – Bass Enterprises
  6. 6. 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
  7. 7. Deepwater Horizon
  8. 8. 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
  9. 9. Hypothermia  Destroys insulation and waterproof features  Lanugo – wooly fur insulationBuoyancy Oiled feathers at weight  Drowning of birds Fur seal pups  Unable to stay afloat with oiled fins
  10. 10. Increased Predation  Inability to fight off predators  Matted feathers  Oiled flippersMalnutrition Causes low body temperature  Metabolism tries to combat cold, body weight diminishes Prey contamination
  11. 11. Damage Scent Coversscent of seal pups  Rejection  Abandonment  StarvationInternal Health Ingestion causes ulcers Stomach bleeding Inflammation and infection
  12. 12. Cleanup Ocean Land Booms  High pressure  Floating barriers hoses Skimmers  Vacuum Trucks Biological Agents  Shovels, Road EquipmentWildlife  Dawn: Saving Wildlife  Rescue Organizations  Donations
  13. 13. OceanCleanupo Boom o Containment o Diversion o Exclusion
