This article provides an application of the silt-suspension theory to a Bayesian-inference inversion for the geo-acoustic parameters in marine mud. The theory, with consequences that have been developed recently, postulates a suspension of water and

Increased understanding of developmental disorders of the brain has shown that genetic mutations, environmental toxins and biological insults typically act during developmental windows of susceptibility. Identifying these vulnerable periods is a nece

Understanding physics of complex media is generally helped by one's having a complete set of partial differential equations that govern the motion and interactions within the media. A single scalar wave equation is usually not sufficient for understa

Present paper considers case of silt-less mud where clay particles are flocculated to a card-house structure, with te flocculation hypothesis yielding a porosity of 90%. During the passage of a sound wave, Van-der-Waals forces between platelets cause

Sound attenuation in marine mud sediments is partly caused by viscous dissipation of acoustically-induced flow past suspended silt particles. Clay particles in the surrounding lattice carry electrostatic charges, causing high porosity, so one asks wh

Work presented at previous meetings and in various publications for propagation of sound through mud continues with a theory that simultaneously takes into account viscous flow past both suspended clay and silt particles. Why silt particles do not se

Mud in marine sediments is a mixture of clay and silt particles. Paper follows a suggestion by Holland and Dosso (JASA, 2013) that the variability of the measured frequency-dependent compressional wave attenuation may be caused by the variability of

Mud consists mostly of particles of clay minerals: kaolinite, illite, and smectite. Particles are hexagonally shaped platelets and have widths of the order of microns. In contrast, sandy/silty sediments are composed of silicate particles that are sph

Recent theory of authors ascribes attenuation in typical marine mud sediments to be caused by viscous interaction of sea water with embedded silt particles. Influence of underlying clay matrix is regarded as passive and of minor importance. Present p
