lo Vertical Distribution 

 The vertical distribution of temperature, salinity and density 

 ((?^) for each of the sections occupied in the Passamaquoddy area are 



shown in figure 16, 



■f 



In section 948-897 the waters are relatively stratified to a 



o 

 depth of 75 metres. Temperatures range from a high of 12,0 G„ at 



o 

 the surface to less than 7o5 C, at the bottom (120 mo), with corres- 



o 

 ponding salinities of 32,3 nnd 33„0 /oo. The density distribution 



in this section, which runs from White Head Island to Pt, Lepreau, 

 affords an ooportunity to determine the general direction of the 

 water movements through this section, B'rom the slopes of the iso- 

 pycnals it is seen that there are tv;o main water movements, one into 

 the section around Pt, Lepreau and one out of the section around 

 White Head. The extent of these two movements varies with deptho 

 In the upper 25 metres the Inward movement extends -almost as far 

 south as station 949 while below this level to the bottom, both move- 

 ments reach as far as station 951, Thus, on the basis of the area 

 of this section, we may s°y that the greatest inward movement is 

 in the upper 25 metres while the greatest outward movement is below 

 this level. 



In section 953-955, across the southern entrance to the G^cnd 

 Mpnan Channel, it is seen that the waters in this area are for all 

 intents and purposes homogeneous in respect to temperature, sf'linity 

 and density. So well mixed are these waters that the Archemedean 

 forces acting on this body of water would be so slight as to be 

 negligible. Thus such a water mass is mainly subject to movements
