Mapping The Ocean FloorSONAR – system that uses sound waves to
calculate the distance to an object.Echosounding – Indirect method used for mapping the ocean floor
using sound waves
Energy waves such as sound waves are sent to the ocean floor from the surface
Sound waves are reflected back to the ocean surface from the ocean floor and the time is recorded by the oceanographer
Knowing the speed of sound in water and the time that it takes the sound wave to travel from the surface to the floor, back to the surface; allows the oceanographers to determine the depth of the ocean floor at a certain point
Ocean Depth = (# of seconds / 2) X 1500 m/s
How deep is the ocean floor if it takes the sound wave 15 seconds to return to the boat?
Step 1 – Write the equationOcean Depth = (# of seconds / 2) X 1500 m/s
Step 2 – SubstitutionOD = (15 seconds / 2) X 1500 m/s
