Tides in the Mediterranean and Adjacent Seas

and northern section. This is explained by the fact that in this southern 

 section, the amplitude of the longitudinal oscillations reaches a maximum 

 towards the open end in the south, and then decreases which requires a change 

 in the sign of the horizontal displacement of these oscillations.

 Transverse lines correspond to the sections used for the theoretical computation. 



The combined longitudinal and transverse oscillations give the tidal picture 

 of the Adria represented in Fig. 171. The agreement with the tidal con- 

 stants of the coastal localities is excellent for both the semi-diurnal and the 

 diurnal tides. 



8. The Tides of the Aegean Sea 



This sea, which has a very intricate configuration, can be considered as 

 a bay of the eastern Mediterranean basin and is connected with the latter 

 by means of the two straits west and east of Crete. The areas of the cross- 

 sections are respectively 25 and 55 km 2 , so that the eastern strait is to be 

 considered as the more important opening. The entire bay, on account of 

 its bottom relief is divided in two basins which are fairly well separated 

 from each other: (1) the Cretan basin, which is bordered in the north 

 by the Cyclade Islands and in the south by Crete, and which has a good
