\begin{abstract}
Sound propagation from a point time-harmonic source in a stratified
water layer lying over an elastic solid half-space is investigated.
It is assumed that the sound speed in the layer is less than the
shear speed in the solid bottom, and that it increases with the
depth. Numerical examples are given which show that the dependence
of the wave field on the range between the source and the receiver
can sharply change the character under rather small variations of
the frequency. Namely, for some particular frequencies, the sound
amplitude shows a periodical dependence on the range, while for
other frequencies there is no periodicity. A theoretical explanation
of this phenomenon is given in a mathematical development using the
normal modes theory and high-frequency asymptotic approximations.
The dispersion phase curves are found to have
``quasi-intersections", i.e., small domains where two adjacent
curves almost intersect. The corresponding frequencies are called
the ``specific" frequencies. For any non-specific frequency, there
is \ {\it one} \ interface Stoneley ($=$ Scholte) mode, whilst for
each specific frequency there are \ {\it two} \ modes of the
Stoneley type with close phase velocities. The periodicity of the
field is a result of interference in the two Stoneley modes.
