A method is presented for the prediction and attenuation of long-period water-layer multiples based on an adaptive multichannel lattice algorithm. The multichannel approach can be viewed as a generalization of two-dimensional linear prediction. The multichannel linear least-squares prediction problem is reviewed briefly and the performance and limitations of the algorithm are demonstrated on two different marine data sets with different properties of the simple and peg-leg multiple system. The algorithm works well even on problematic data sets and is very easy to apply.
