found In the offshore vj^tev?. , Tine waters nenr the entrance to 



o 

 P-^ssgmaquoddjr Boy hsve s'llinlties slightly higher (less thfin 32 o5 /oo) 



than the w«*ters proceeding from the Siint John rep-ion (less than 

 o 



32.4 /oo) wViile the salinities in the Grnnd Knnnn Channel range from 



o 



32.5 to 32.7 /oo) . 



At 50 metres (figure 22) the waters of lowest salinity (less than 

 o 

 32,50 /oo) are to be seen proceeding from the Passamaquoddy region. 



Between Grgnd I/lanan and the mainland the v/Qters have salinities rang- 



o 

 Ing from 32,60 and 32,70 /oo, while the salinities in the offshore 



o 

 v;aters are grentor than 32.9 /oo . 



( c ) Density 



The horizontal distribution of density i^t) at 1 metre 

 (figure 23) shov/s that the lightest water at this level is to the east 

 of the area under investigation and flowing from the Saint John region. 



Figure 24 illustrating the distribution of density (<ni-) at 

 25 metres shov/s that the waters from the north of the area are flowing 

 southwestward and sweeping in toward Passamaquoddy Bay just north of 

 Grand Ivlonan. The lov/ densities in the approaches to Passamaquoddy 

 Bay indicate that the waters in the region are flowing away from the 

 area to the east of Grand Manan, Since the area is so strongly In- 

 fluenced by the tides it is Impossible, using normal nrocedures, to 

 get adequate data that will support an analysis presupposing simul- 

 taneous observations. 



At 50 metres (figure 25) the v/aters are seen to b e moving towards 

 the entrance to Passamaquoddy Bay from the northeast past Pt , Lepreau, 

 and fromi the south through Grand Manan Channel.
