The Australian Beach Safety & Management Program (ABSAMP) was established in 1990 as a joint program between SLSA and the Coastal Studies Unit and the University of Sydney, and is the most comprehensive study ever undertaken on the beaches of any part of the world's coast.
More Acoustic backscatter refers to the component of sound waves emitted by a sonar that are reflected from the seabed back in the direction from which they came.
This includes sidereal, isotopic, radiogenic, and chemical dating methods.
An introduction to dating techniques: a guide for geomorphologists.
The intensity of backscattered energy depends on a number of factors including the angle of incidence of the acoustic beam, the acoustic wavelength, and the 'roughness' or scattering properties of the seabed.
