ASFA 2: Ocean Technology,Policy and Non-Living Resources

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.

    AB: 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.
