Added mass for wave motion in density-stratified fluids

In a density-stratified fluid the existence of a restoring force - buoyancy - alters fundamentally the dynamics of submerged bodies. This effect can be described as a modification of their added mass. We investigate it in the simplest possible configuration - the small-amplitude motion of an unbounded Boussinesq uniformly stratified fluid - and for the simplest possible bodies - a horizontal circular cylinder in two dimensions and a sphere in three dimensions.
