The sonar systems calculate the time each pulse takes to reach the seafloor and return, then translates those times into water depths, allowing us to uncover the bathymetry below us.

How can sonar be used to map the ocean floor?

Multibeam sonar signals are sent out from the ship. With about 1500 sonar soundings sent out per second, multibeam “paints” the seafloor in a fanlike pattern. This creates a detailed “sound map” that shows ocean depth, bottom type, and topographic features.

Why is it that we use sonar to study the ocean floor?

Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.
