Tides in the Mediterranean and Adjacent Seas

diurnal lidal components in front of the Cabot Strait, the diurnal tides will 

 only be very little developed. As v = 03, we will only be very little developed. 

 As v = 0-3, we will have a simultaneous rise and fall of the water surface 

 of the entire Gulf. The harmonic values seem to confirm this. According to 

 Dawson, the daily inequality in the Northumberland Strait increases from 



Table 67. Harmonic constants for the Gulf of St. Lawrence 



east to west; the tidal currents also show irregularities here which, according 

 to Springstubbe, can be explained from the co-oscillation of the water-masses 

 in the canal with the tides at the openings in the west and in the east. Dawson 

 also points out the surprising reversal of the daily inequality between the 

 opening in the Cabot Strait and the opposite coasts in the west, i.e. if on 

 a certain day the morning tide is higher in the east, the evening tide will be 

 higher in the west. Krummel sees correctly in this the effect of the standing 

 (semi-diurnal) wave. 



19. The Tides of the Bay of Fundy 



The Bay of Fundy has the largest tides of the earth and, therefore is of 

 great interest. The bay forms a narrow bend extending to the north-east off 

 the wide Gulf of Maine which in its centre has a depth of more than 200 m 

 (650 ft). It is bordered on both sides by high, rocky, steep banks, and its 

 width varies only little until it bifurcates into two canal-like arms. The 

 Advocate Peninsula separates the Chignecto Basin from the Minas Basin. 

 The water depths are still more than 100 m (320 ft) at the opening, then gra- 

 dually decrease to 50 m (160 ft) in front of the bifurcation. In the Minas Basin, 

 the depth decreases to 20 m (65 ft) and less, and the Basin ends in sand 

 and rock banks. Table 68 gives a survey of the variations of the establishments 

 and tidal ranges at spring tide along the entire bay. One notices that in the 

 outward section high water occurs almost simultaneously; the lag up till the 

 bifurcation is only 24 min and this happens only in the last section. In the 

 Chignecto Basin there is a further lag of 26 min up to Sackville ; it is greater 

 in the shallower Minas Basin. Near Noel high water occurs around 1 h 40 min 

 after high water at the opening. The tidal ranges at the opening are not very
