    Abstract: Solid information on the present environment and its effect on acoustic wave propagation is key to conducting and planning a successful sonar operation. \nIn recent years, the quality and avaliability of oceanographic model data has increased significantly. However, the vastness of information contained in these models leads to high complexity and possibly very long computation times. We propose a method for organizing the ocean masses in geographically divided areas with\nsimilar sound speed profiles by using empirical orthogonal functions and clustering. The expected sonar performance and its uncertainty are estimated by using representative sound speed profiles for each area and compared with an exhaustive run for the entire model area. The method is demonstrated and explored using ocean model data sets from Eggakanten outside Lofoten in Northern Norway.
