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
