Internal wave motions are considered in a thermocline that consists of thin sheets across which there are abrupt changes in the density. These sheets are separated by homogeneous layers of water in which there is turbulent mixing. Investigations have been undertaken to determine the dependence of both the rate of energy dissipation and the dynamical stability upon the number of sheets in the thermocline....
