1. Ocean Technology 8 th Grade Science SWMS

2. Ocean Technology How we explore the ocean! Some major ways: – Sonar – Buoys – Submersibles

3. Sonar Using SOUND waves to determine depth and structure. Length of time for waves to return = distance. Longer Time = Deeper Shorter Time = Shallow How SONAR works

5. Submersible Vehicles that can submerge, or go under water. Robotic vs. Manned Explore the deep ocean!

6. Unmanned Submersible  Manned Submersible 

7. Buoys Floating devices that are used for: – Measure water properties (temp, pH, etc.) – Sonar – Navigation markers

11. Oceans in 3D hydrothermal vents
