In the wake of growing concern over limited natural resources, scientists and engineers are increasingly turning to the sea for answers. ASFA 2 is the source that puts professionals in touch with effective management solutions, alerts them to problems, and updates them on new legislation that affects management practices. Coverage spans the wide-ranging fields of oceanography: physical, descriptive, dynamical, chemical, geological, and biological aspects are extensively examined, as well as limnology, ocean engineering, and specific resources. From international policy and legislation to meteorology and climatology to technology and engineering, ASFA 2 covers the crucial current issues.

Abstract
A system of differential equations is derived from Biot's constitutive
and motion equations for a poroelastic material. The seabed is
modeled as a poroelastic layer over a rigid substrate. A residue
expansion for pressure in the far field is found in the case of
constant parameters. The model's prediction for transmission loss
is examined for five different types of sediments. |
