    4.1 The accuracy of depth measurements made by a fathometer or echo sounder requires a number of corrections because of the variability of sound or acoustic velocity in water with changes in temperature, salinity, and depth of water. In addition instability of the equipment can also result inMeasuring water depth Echosounding,Measuring water depth Echosounding Historical Note. To measure ocean water depths before the development of echosounders, a heavy line was lowered to the seafloor. The length of line that it took to reach the bottom was measured and recorded. This was called "sounding". The H.M.S. Challenger is shown in the figure to the right with a line over the side. The Challenger expedition which set
