Sound travels more slowly in the SOFAR channel than in the areas of the ocean immediately above and below it.

Question

Quizplus · Accepted Answer

The SOFAR channel (Sound Fixing and Ranging channel) is a layer of ocean water where sound travels at its slowest speed due to a combination of pressure, temperature, and salinity conditions. This area acts as a waveguide, reflecting and refracting sound waves, making it valuable for long-range underwater communication and detection of seismic activity. Sound travels faster in the upper and lower layers of the ocean due to the differences in temperature and pressure.
