  1. Modern Ocean Research-Submersibles Lesson 1.2: *Refer to Chapter 2 in your Textbook

  2. Lesson 1.2 Learning Targets: • I can describe the major advancements of research in oceanography over time. • I can compare & contrast the different types of marine submersibles.

  3. Ocean Explosion • Inventions during the 1900’s: • Steal/iron ships with engines • Echo sounding mapping • Submersibles • Self- contained diving • ROV’s/AUV’s • Electronic navigation & Satellites

  4. Ocean Explosion • The German Meteor (1925) • Primary accomplishment was mapping the Atlantic ocean floor using echo sounding technology

  5. Ocean Explosion • U.S. Atlantis (1931) • Confirmed the existence of a mid-ocean ridge= underwater mountain chain

  6. Ocean Explosion • HMS Challenger II (1951) • Used echo sounding to map the depth of the Pacific & Indian Oceans • Discovered the deepest part of the ocean in the Mariana’s Trench • 10,914 meters / ~7 miles

  7. Submersibles • Bathysphere (1932) • William Beebe & Otis Barton • Steel ballwith a window • Attached to a cable from a ship • Only went up & down

  8. Submersibles • Bathyscaphe • Similar to bathysphere, but not attached to a ship • Instead has a floatthat contains a liquid that is buoyant in water (ex. gasoline), & heavy ballast water to move up and down • Small motor to move side to side (though very limited)

  9. Bathyscaphes • Trieste 1960 • The 1st time the deepest part of the ocean was ever visited by man • Located in the Mariana’s Trench • Claim to have seen a fish, jellyfish, and shrimp

  10. Submersibles • Bathyscaphe

  11. Submersibles • Deep Diving Submarine • Large variety of shapes & sizes • Move both vertically & horizontally • Some have robotic arms to grasp samples or perform experiments outside the submersible • Most current & technologically advanced

  12. Submersibles • Deep Diving Submarine • James Cameron 2012visited the deepest part of the ocean for the 2nd time ever! • Updates since the Trieste: • Color pictures & videos • Collected samples
