Active Remote Sensing Acoustic! multiple, focused, high-frequency, short wavelength sound beams “narrow-beam” or “multibeam” bathymetry –sound beam stays narrow and focused all the way to the bottom –depths much more precise –e.g., Sea Beam has 16 beams, Sea Beam 2000 has 121, EM3000 has 127, EM120 has 191
