A computer program is utilized to examine the effect on sound propagation of the oceanic polar front in the Denmark Strait and along the Southeastern coast of Greenland. Ray traces are computed with the source in both the cold and warm current areas for surface thermal gradients of 0.036 C/KM to 1.68 C/KM. These gradients are created by varying horizontal distances between actual oceanographic stations. The results indicate greater trapping angles with the source in cold water. A relationship is reported between the surface thermal gradient and the change in trapping angle difference for pairs of runs. The location of the oceanic polar front and the effects of environmental influences on its strength and seasonal movement are described.
