JOE Special Issue on Sediment Acoustic Processes

Call for Papers

Announcing a Special Issue on Sediment Acoustic Processes for the April 2008 issue of the IEEE Journal of Oceanic Engineering.

Guest Editors:

Eric I. Thorsos, Applied Physics Laboratory, University of Washington
Michael D. Richardson, Naval Research Laboratory, Stennis Space Center
James F. Lynch, Woods Hole Oceanographic Institution

This special issue is devoted to quantifying the effects of sediment properties and seafloor morphology on dispersion, attenuation, reflection, and scattering of acoustic waves, and on acoustic detection of buried targets. Papers are solicited on acoustic and environmental measurements and modeling pertaining to scattering from, penetration into, and propagation within shallow water sediments at frequencies above 100 Hz. Papers on environmental processes, measurements, or modeling need not include acoustic components, but authors of environmental papers are encouraged to discuss relevance to acoustic measurements or modeling.

Specific topics of interest include the following:

- Measurement and modeling of sediment hydrodynamic, geological, and biological properties and processes that pertain to sediment acoustics (e.g., seabed roughness, sediment heterogeneity, propagation-model parameters, sediment microstructure, bioturbation).

- Monostatic and bistatic scattering (and reflection) from the seafloor; scattering from discrete scatterers (e.g., shells).

- Acoustic penetration into seafloor sediments, especially at subcritical grazing angles.

- Volume scattering and its effects on wave propagation in sediments.

- Modeling of wave propagation in sediments, including the dependence of wave speeds and attenuations on physical properties (e.g., grain size, porosity and overburden pressure) as well as frequency.

- Acoustic detection and classification of buried objects.

Manuscripts must be submitted online by March 1, 2007 at http://joe.msubmit.net where authors may find all the necessary formatting and submission information.
