Sonar used to map ocean floors can penetrate polluted and turbid waters
Is it true that Sonar used to map ocean floors can penetrate polluted and turbid waters?
Yes. Sonar is well-suited for mapping ocean and inland floor bathymetry because acoustic waves penetrate turbid and polluted waters where optical methods fail.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The retrieved literature consistently supports the fundamental premise that acoustic remote sensing (sonar) is not hindered by water turbidity, unlike optical remote sensing methods which suffer from electromagnetic attenuation in cloudy or turbid waters.
