    • 9 th Grade Chapter 4 Lesson 4 Pgs. 101-109 For Student Use Only
    • Oceanography: Study of the Sea
      • Began with Spanish and Portuguese explorers
      • Matthew F. Muarry- studied wind patterns, ocean currents and temperature
      • 1870- H.M.S. Challenger collected massive amount of data
    • Oceanography: Study of the Sea
      • In 20 th century (1900s) new tools helped gather information
        • Diving Suits
        • Submarines
        • Satellites- for ocean surface
      • Tools of Oceanography
        • Surface Vessels
          • Oceanographic Research Ship
            • Labs, instruments, library, research team cabins, and crew cabins
    • Oceanography: Study of the Sea
      • Tools of Oceanography
        • Knorr- oceanography research ship

    • Oceanography: Study of the Sea
      • Tools of Oceanography:
        • FLIP: Floating Instrument Platform
          • Does not move on its own, but is towed where it needs to go

    • Oceanography: Study of the Sea
      • Tools of Oceanography:
        • Oceanographic Buoys:
          • Used to measure sea and weather conditions automatically (cheaper than ships)
          • Independent Breathing Devices:
            • 1700s – underwater breathing devices were extremely heavy
            • Jacques Cousteu- invented aqualung on 1943- allowed people to swim freely
            • SCUBA- Self-Contained Breathing Apparatus- allows diver to breathe and swim freely
    • Oceanography: Study of the Sea
      • Tools of Oceanography:
        • SCUBA Gear:

    • Oceanography: Study of the Sea
      • Subsurface Vessels:
        • Submersibles: small research submarines
          • Examples:
            • Alvin
            • Deep Rover
            • Deep Flight
        • Remote Vehicles: controlled by remote control
          • Examples:
            • Argo
            • Jason Jr.
    • Oceanography: Study of the Sea
      • Subsurface Vessels:
        • Modern Technology has helped create unmanned submersibles
          • Examples:
            • ABE- Autonomous Benthic Explorer
        • Manned undersea labs:
          • Located on Continental Shelf:
            • Conshelf 1
            • Sealab (Navy)
      • (See video Clip Notes)
    • Oceanography: Study of the Sea
      • Instruments of Oceanography:
        • Sound Measurements:
          • SONAR: Sound Navigation and Ranging
            • Uses sound waves
          • Sonoprobe:
            • Indicates thickness and composition of sediment

    • Oceanography: Study of the Sea
      • Instruments of Oceanography:
        • Currents
          • Drift Bottles- original way to study currents
          • ALACE- (Autonomous Lagranging Circulation Explorer)- drifts with currents and transmits data
          • Rosette- clusters of insulated bottles that open and close at different depths
          • Piston Corer- brings back core samples of sea floor
