Some effects of large-scale oceanography on acoustic propagation
A propagation experiment was conducted along a great circle track in the North American Basin, beginning at a point 400 km north of Antigua, W.I. and ending at the Grand Banks of Newfoundland. Shallow explosive sources were detonated at half hour intervals and shallow-13.89 and 111.1 Hz cw sources w...
