Webb13 nov. 2024 · For example, given an echo with a delay of 0.5 s from the transmitted signal and the speed of sound in water (c = 1,480 m s –1 ), Equation 3 tells us that d = (1,480 m s –1 ) (0.5 s) = 740 m. The estimated seafloor depth is 370 m, half of the total distance traveled to and from the seafloor by the transmitted signal. Figure 2. WebbThis method of seafloor mapping is called echosounding.
