A model is reported for wave propagation through a marginal ice zone (MIZ) based upon the finite floe solution of Meyland and Squire (1993a,b, 1994). It is shown first that an approximate solution which neglects interaction between adjacent ice floes is amply precise in most circumstances. Then the propagation of waves through an array of discrete, non-colliding floes based on the addition of energy is considered, assuming that floe lengths are Rayleigh distributed. It is found under these conditions that an MZI is analogous to a low-pass filter to incoming ocean waves, with filter characteristics a function of average floe length, floe thickness and the number of floes present.
