Abstract
Normal-mode expansions for Green's functions are derived for ocean-bottom s ystems. The bottom is modeled by Kirchhoff and Reissner-Mindlin plate theor ies for elastic and poroelastic materials. The resulting eigenvalue problem s for the modal parameters are investigated. Normal modes are calculated by Hankel transformation of the underlying equations. Finally, the relation t o the inverse problem is outlined.
