WebSonars are useful for the detection of fish and biomass estimation. In recent years, high powered laser systems operating in the blue- green portion of the visible spectrum (lidar) have shown promise for the evaluation of fishery resources. A lidar carried on aircraft flying at an approximate altitude of 1700 m can detect fish at depths to 16 m. WebThis kind of wave travels along a surface between two media. If you've ever been in an earthquake, surfed the inside of an ocean wave, or blown across the surface of a cup of tea, then you've seen a surface wave.
