Ocean Floor Features

*Scientists study the ocean floor using sound waves called SONAR – Sound Navigation and Ranging

*The satellites Seasat and Geosat are also used to study the ocean floor.

*Submersibles are also used to study the ocean floor:

   A) piloted vessels:  Alvin and Deep Flight

   B) robotic vessels:  Jason II and Medea

*Using robotic vessels is cheaper and not as risky as a piloted vessel
