Remote sensing of sound speed and temperature in the ocean Academic Article

For the remote sensing of temperature profiles in the ocean, Brillouin scattering can be exploited as both a sound speed and a temperature tracer. Such a light detection and ranging (LIDAR) system is capable of delivering online data from an extended region of the ocean. The acquired sound speed/temperature profiles can give valuable input to climate studies, weather forecasting and sonar analyses.1Recent progress promises the realization of practical systems in the near future.
