An algorithm is proposed to numerically integrate the inhomogeneous
depth-separated wave equation using a state variable technique. The solution
obtained for two simple shallow water models is shown to agree well
with the known exact solutions. Integration grid density is discussed and
a minimum required density specified.
The use of complex sound speeds to simulate bottom attenuation is
reviewed. A numerical instability inherent to the technique that arises
during the use of complex sound speeds is investigated.
The algorithm is also applied to a deep ocean profile, and the solution
characteristics discussed. Sensitivity problems that arise when modelling
the seafloor as a layered elastic medium are analyzed.

Stability of a coastal upwelling front over topography
Barth, John A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-10)A two-layer shallow water equation model is used to investigate the linear stability of a coastal upwelling front. The model features a surface front near a coastal boundary and bottom topography which is an arbitrary ... -
Seismic constraints on shallow crustal processes at the East Pacific Rise
Christeson, Gail L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-02)This thesis is concerned with understanding how oceanic crust is emplaced at mid-ocean ridges. The emphasis is upon fast-spreading ridges, and the use of seismic techniques to image the uppermost several hundred meters ... -
