Retrieval of sound-velocity profile in ocean by employing Brillouin scattering LiDAR

Jiulin Shi et al.

Summary: This paper proposes a new method based on stimulated Brillouin scattering (SBS) LiDAR for accurately detecting the sound velocity profile of upper-ocean mixed layers. By theoretical and experimental methods, the sound velocity profile of the upper-ocean mixed layer in the South China Sea was successfully retrieved.

Influence of temperature-salinity-depth structure of the upper-ocean on the frequency shift of Brillouin LiDAR

Ning Xu et al.

Summary: Brillouin-based LiDAR is an alternative remote sensing technique for measuring temperature, salinity, and sound speed in the upper ocean mixed layer. Seawater temperature has the most significant impact on Brillouin frequency shift compared to salinity and pressure. The experimental results closely align with theoretical simulations, indicating the potential for future applications of Brillouin LiDAR in ocean remote sensing.
