← ScienceWhich risk increases for surface ships equipped with sonar when intense thermoclines generate underwater turbulence?
A)Doppler shift measurement errors increase✓
B)Signal attenuation becomes exponentially higher
C)Increased algae growth on transducers
D)Waveguide effects become negligible
💡 Explanation
Turbulence induced by thermoclines causes variations in the speed of sound, because it introduces localized regions of different densities. Subsequently, Doppler shift accuracies decrease as signal distortion impacts frequency estimation, therefore erroneous speed estimates occur, rather than simple absorption changes happening.
