SOUND IN THE OCEAN
Explain how SOUND travels. (What kind of wave?):
Explain the SOFAR channel:
Explain how marine organisms may use sound in the ocean (Voices in the Sea):
Explain how people use sound (sonar) in the ocean (military, exploration) :
Watch video and explain how SONAR is used to map the ocean floor
Explain how SOUND travels. (What kind of wave?):
- S-Wave (sheer): A type of elastic wave, the S-wave, secondary wave, or shear wave (sometimes called an elastic S-wave) is one of the two main types of elastic body wave, so named because they move through the body of an object, unlike surface waves. S-waves travel slower in rock
- P-Wave (pressure): P-waves are a type of elastic waves, called seismic waves in seismology, that can travel through a continuum. The continuum is made up of gases (as sound waves), liquids, or solids, including the Earth. P-waves can be produced by earthquake and recorded by seismographs
Explain the SOFAR channel:
- The Sofar channel is a section in the ocean where sound travels slowly and dose not rise to the surface or reach the bottom of the ocean .
Explain how marine organisms may use sound in the ocean (Voices in the Sea):
- Marine organisms may use sound through the process of collocation where animals bounce sound waves off objects in order to identify them
Explain how people use sound (sonar) in the ocean (military, exploration) :
- People use a process called sonar in which sound waves are produced and when they bounce back information about the geography and inhabitant of the ocean are received.
