Ellen is applying for a summer internship creating high-resolution sea floor maps for a government agency. If she gets the internship, which sonar technology would she MOST likely use to create these images?

Question

A. multibeam sonar because it sends one signal at a time
B. side-scan sonar because it sends large amounts of sound signals
C. side-scan sonar because it sends large amounts of light signals
D. multibeam sonar because it is a classified technology

Answer 1

B. side-scan sonar because it sends large amounts of sound signals

Side-scan sonar is commonly used for creating high-resolution sea floor maps because it sends out a fan-shaped beam of sound signals that can cover a larger area and provide detailed imagery of the sea floor.
