  1. SHORT HISTORYSUBMERSIBLES • Average depth of ocean is 3,700m. • Deepest Scuba dive is about 135m • Scuba limitation: cold, pressure

  2. TIME LINE • 1934 Dr. William Beebe reached a depth of 1000 meters in a steel chamber called a Bathysphere ( fits 2 people).

  3. Beebe’s Bathysphere

  4. TIME LINE • 10 min video

  5. In 1960 a Swiss team of Auguste and Jacques Piccard, made the deepest dive in a submersible (bathyscaphe) to the bottom of the Mariana Trench (10,852 meters- 4 hrs.).

  6. cameron's dive in 1 min (2min) • dive to marianna

  7. 1964 - Alvin is a submersible that has logged in over 1000 dives. It holds a crew of 3.

  8. 1966- ALVIN recovered hydrogen bomb • Investigates hydrothermal vents

  9. restructure of alvin to 2013 6 min

  10. Alvin

  11. 1979 -Dr. Sylvia Earle holds the record for the deepest solo dive- 380 meters. (Jim Suit)

  12. New Suit (2 Min)

  13. The Jim Suit

  14. Dr. Earle Dive (7min) • Dr. Earle and deep sea diving (2 min) • Dr. Earle and exploration 11 min

  15. Using high tech submersibles specially outfitted to withstand the cold temperatures and high pressure of the deep ocean.

  16. How do Modern Submersibles Explore the Ocean Floor? ROVs – Remote Operated Vehicles

  17. JASON • Robot connected by cables from a surface ship WHAT JASON SEES 35 SEC

  18. How was the Titanic Found?

  19. Why were scuba divers not used to locate the resting place of the Titanic?

  20. Sonar • Sonar stands for sound navigation and ranging. • Sonar uses a beam of sound waves directed downward • Sound wave will bounce off and return back causing an echo. • Image of bottom or object is created

  21. Sonar

  22. Sounding the Deepest Spot on Earth 1 min

  23. JAMES CAMERON • Long Way Down 2 min • long way down 3 min

  24. Summary The development of advanced technology, in the form of submersibles, robot vehicles, and sonar equipment has opened up the fields of Marine Biology and Oceanography in a way we could never have imagined!
