🌐 How SONAR Uses Sound to Map the Hidden Ocean Depths
From section: 🐋 Listening to life in the oceanThis biological perspective connects back to the earlier discussion of sound propagation. The same physical principles that guide SONAR pulses also shape how animal sounds travel through the ocean, which provides a natural path toward understanding how SONAR technology developed over time.
