In pnrticulnr, it is Heen thcit nt Isle Haute, nt the he^d of the B^y, 



o 

 the temperatures rnnged from greater thnn 14.0 C, in August, 1929, to 







less than -1,0 C, in February, 1930. At St. Andrews, the temperatures 



o 

 ranged from greater th-^n 13,0 C, in August and September, 1929, to 



o 

 -1,0 C. in January and i^'ebru-^ry of the following year. In 1929, at 



o 

 Grand M^nan, the highest daily average temperature was 11,0 C, in 



o 

 late September, with the lov/est of -1,0 C. in l^'ebruary 1930, At 



o 

 Lurcher Lightship the highest daily average temperature of 12,0 C, 



*^ was recorded in August 1929, while the lowest was 2.0 C, in February, 



1930. Thus, in comparing the annual ranges for the varjous points, 



the efficiency of mixing in different areas in the Bay of Fundy can 



be appreciated. These annual ranges are as follows:

The range in temperfrture at Isle Haute, St, Andrews, and G^gnd 



o o 



Manan shov/ a gradation from 16 C, at the hend of the Boy to 13 C, at 



the mouth. These results further Illustrate the results of pro- 

 gressive mixing of the waters that take place in the Bqy, During 

 the' summer months, the bottom waters nt the mouth of the B,qy h-^ve 

 comparatively low temperatures. Mixing, v/lth the resultant bringing 

 up of bottom v/ater, tends to keep the surface temperatures low. As 

 a result of this m^lxlng, the bottom, v/aters further up the Bqy hnve 

 slightly higher tem.peratures than those at the mouth. Consequently, 

 their effect on the temperature of the surface water is not ^s great.
