same time, conditions ^re chonping so ropldly thctt the results ob- 

 tained over p period of time could not be counted upon to give 

 reliable results. Consequently, of thn d"tq collected in n survey 

 carried out during the freshet of 1950, only salinity values are 

 used. The locations of the stations occupied during this survey of 

 the area from April 17th to May 8th, 1950, are given in figure 15. 



The horizontal distribution of salinity at 0, 10, 25 and 50 metres 

 is shown in figures 26, 27, 28 and 29 respectively. In the surff=ice 

 distribution (figure 26) the most prominent body of w«>ter resulting 

 from the spring freshets is that proceeding from the Snint John River 

 region. The main movement is outward from the Saint John Estuary, 

 swinging to the right as It progresses, ^nd definitely outlined as 



far as the eastern extremity of Grand Manan. The salinity of the 



o 

 main outflow varies between a value less than 27,5 /oo and q value 



o 

 greater than 51,6 /oo, while the waters from the Possamaquoddy 







region have salinities greater th^in 51,8 /oo , The temperatures of 



o o 

 the vnrious waters range from 0.95 to 6,65 C. at the surf nee, qnd 







from 1.25 to 4.90 C. at the bottom, thus the relative values of 

 the densities would be roughly in the same proportion as the salini- 

 ties. Consequently, the waters from the Soint John region eventually 

 cover or mix with the waters from the P^ssnmaquoddy ars^ , There 

 appears to be considerable movement of the fresher and therefore 

 lighter waters from the Saint John area to the Possamaquoddy area. 

 The greatest movement, as has been previously pointed out, is from 

 the Saint John area towards Grand Man^n. The water from the Possa- 

 maquoddy area penetrates into Grand Manon Channel, and then flows 

 into the Bay of Fundy around the north shore of Grand Manan. It
