Tides in the Mediterranean and Adjacent Seas

Sakhalin and the continent. This deep adjacent sea will, therefore, receive 

 its principal impulse for the tidal motion through the Strait of Tsushima. 

 Table 60 contains a compilation of the tidal constants of the most important 

 coastal localities, for numerous other localities they can be found in the 

 above mentioned paper of Ogura. Figures 182 and 183 represent the co-tidal 

 and co-range lines, according to the latter.

The semi-diurnal tidal wave penetrating from the south shows a well- 

 developed amphidromy at the northern outlet of the Strait of Tsushima, 

 which has already been assumed at this point Harris (1900, 1904). The length 

 of the entire strait is estimated to be 280 miles (450 km), its mean depth around 

 328 ft (100 m) this gives a natural period of 8 1 h and v =0-65. As the 

 difference in phase at both ends of the strait is exactly 1 80°, the distribution 

 of the amplitudes along the same is according toDEFANT(1919, p. 105) given by
