  1. Trapping Trash Designing a Structure to Remove Marine Debris

  2. What comes to mind when you think of the ocean?

  3. How have humans affected marine environments?


  5. What is Marine Debris? • Includes objects that don’t occur naturally in the marine environment • Oceans, salt marshes, estuaries, beaches • Marine debris can be classified by the activity that created the waste item • “ocean and waterway activities”, “illegal dumping”, “smoking-related activities”

  6. Marine debris comes from MANY different sources! Where do you think marine debris comes from?

  7. Main Sources of Marine Debris • Beachgoers • Improper disposal of trash on land • Stormwater sewers and combined sewer overflow • Ships and other vessels • Industrial facilities • Waste disposal activities • Offshore oil and gas platforms

  8. Effects of Marine Debris • Entanglement • Ingestion • Habitat Degradation • Unsightliness • Costly Cleanup

  9. What Characteristics Affect the Presence of Debris in the Marine Environment?

  10. Buoyancy • The ability of something to float in water • Trash can become marine debris even when it is properly disposed of!

  11. Photodegrade • The process by which a substance or object is broken down via sunlight • In nature, materials are broken down through a process called biodegradation

  12. What is a Gyre?

  13. North Pacific Gyre

  14. North Pacific Gyre Cont. • 2 times the size of Texas • 90% of all trash in the ocean • Plastic doesn’t break down • Photo degrades • “Mermaid tears” • Kills wildlife, damages boats, is unsafe • Nets for cleanup harm marine organisms

  15. What YOU can do to help! • REDUCE your wastes • REUSE products • RECYLE plastics, cardboards, and metals! • Pick up trash at your local beach!! • Proper disposal of trash • Secure your trash • Become an Ocean advocate • Educate others about the impacts marine debris has on our environment!


  17. What are we doing today? • Today, you will be designing a machine that can remove trash from the ocean! • When designing your trash collector, take these things into consideration: • How does it avoid harming wildlife? • How does the machine run? • What happens to the trash after it’s collected?
