The previous chapter (Chapter 2) presented basic acoustic theory, from the generation of a sound wave to its scattering on/in the seabed and its reception by the sonar platform. Acoustic pressures are used to quantify the response of the seabed at the particular frequency used. These backscatter measurements are combined across-track to create a swath,

Marine Geology, 1967
Abstract Trace fossil communities are mainly bathymetry-controlled. Their relative depth sequence has been established in sedimentary series of up to Cambrian age. Actual depth figures can now be added from counterparts in the present oceans. As exemplified by the spreite burrows, behavioural response to a bathymetric gradient in food suply is ...

Smoothing bathymetry is a necessary step of any run of ROMS. Here the software bathymetry is demonstrated that allows optimal solution of the problem for a fixed roughness factor.

Laser Bathymetry in the Netherlands
1992Four institutes were involved in a common program to study the potentials of an airborne laser bathymetry system. Apart from the determination of the water depth, a laser bathymetry system can also be applied for measuring the scattering properties of the water and for obtaining information on the water surface.
