Figure 2.  Acoustic backscatter profiles form the 2010 Mud MURI field program showing  scattering from suspended sediment (15 to 80 cm), a fluid mud layer (1 to 15 cm) and the stationary seafloor (0 cm). b through e) Along beam velocity profiles for each of the 4 individual frequencies that are used in the multi-frequency inverse showing two cycles of a 5 s period wave. The velocity aliasing can be seen as the sharp transition from blue to red (discontinuity of 0.24 m/s ) at t=178 s in panel b, and  t = 174, 176 and 178 of the higher frequencies. f) The result of the multi-frequency inverse showing the de-aliased velocity profiles.
