   There are two common methods to obtaining sound velocity in water using the probe method. Firstly, the main three variables that affect sound velocity may be measured using a Conductivity, Temperature & Depth Probe (CTD Probe). This instrument can determine the salinity, temperature and pressure variables, and then calculate the sound

   This feature is referred to as bottom-track. The process has two parts; first identify the position of the bottom from the acoustic echo, then calculating the velocity from a window centered around the bottom position. When an ADCP is mounted on a moving ship, the bottom track velocity may be subtracted from the measured water velocity.

   A multibeam echosounder is a device typically used by hydrographic surveyors to determine the depth of water and the nature of the seabed. Most modern systems work by transmitting a broad acoustic fan shaped pulse from a specially designed transducer across the full swathe acrosstrack with a narrow alongtrack then forming multiple receive beams (beamforming) that are much narrower in the ...
