2pUW31. Scholte--Stoneley waves on a solid layered ocean floor.
Dept. of Phys., Catholic Univ., Washington, DC 20064
The existence of a Scholte--Stoneley interface wave has been pointed out
for the two-layer propagation model of Pekeris, as generalized to a
shear-supporting ocean bottom. Further, the occurrence of apparent resonances
in a solid sediment covering the ocean floor has been noted [S. J. Hughes et
al., 1283 (1990)]. By finding the poles in the complex frequency plane
corresponding to the various interface-wave (Scholte--Stoneley) and
trapped-wave modes (including Love waves), a detailed study is carried out of
the various wave modes that exist in the elastic layered problem taking note of
their identities and of transitions between mode types, and the resonance
behavior associated with them is investigated.
