Strategic Objectives
• Decode the complex relationship between salinity, pressure, and sound speed.
• Navigate the treacherous 'Sea' layer where traditional electromagnetic laws vanish.
• Understand the mechanics of signal attenuation and multi-path interference.
• Master the environmental variables that dictate underwater transmission success.
The Core Challenge
Radio waves die in seconds beneath the waves, leaving subsea technology isolated and blind without a mastery of acoustic physics.
