 note = {Since 1962, measurements of the time differences of Loran ground waves propagating over the sea surface of Southern Kyushu has been performed to investigate the characteristics of variations. In the previous papers, the author suggested that the velocity of Loran ground wave over the sea surface is faster than that of the standard used on a computed Loran table. As is shown in Figure 3, 4 and Table 3, 4, 5, though the distances over the land to the section I, IV and V nearly the same, there is the difference that amounted to about 3 microseconds between the errors of 2S6 and 2S7 in these sections. But the errors of 2S7 in the three section were almost equal. Therefore, it is suggested that these differences are due to the probable variations in the conductivity of the path over the sea. The deviation may be enhanced with increasing distances of propagation. The conductivity may vary with some physical conditions of the path, which in this case would be influenced by the warm current “Kuroshio”.},
