During the winter months the bottom vmters from outside nre of com- 

 paratively high temperjjtureo The quantity of outside bottom w^ter 

 brought into the B^y during the winter months is probably nt n mini- 

 mum due to the rel'^tively sm-ill amount of surface outflow. Consequent- 

 ly, the mixing process exerts Pt minimum effect on the .surface tempera- 

 tureg with the result thn t little difference is to be found between the 

 minimum daily average temperature nt different ports of the ^ay. The 

 general cold surface water? present throughout the summer months is 

 productive of n considerable amount of fog in the ^py of Fundy region. 

 It is probable that the minimum amount of fog occurs at the he^^d of 

 the Bqy while the maximtim occurs ^t the m.outh. This factor must be 

 taken Into account in dealing with the aver-^ge dally w^ter tem.peratures 



at different parts of the Bgy, The range in temperature at Lurcher 



o 

 Lightship is 13.0 C, a minimum for the whole region. Temperatures in 



o 

 the vicinity of 15.0 C, were obtained, over a very short period in 



1931 only, as may be seen from the plotted results. The 'Absence of 



fog in this region during this time is a probable explan^^tion of 



this short tem-perature rise. Lurcher Lightship Is so located that 



the waters in this area are always effected to a considerable degree 



by the waters from the open ocean. This fact Is clearly shown by the 



o 

 temperatures in the winter months ^ with a minimum value of 2„0 C„ 



Summary of Results 



(a) The large tides coupled with the nature of the bottom configura- 

 tion are responsible for the specific hydrographlc conditions found 

 in the Bay of Fundy. 



(b ) The bottom of the Bay consists of three important types; mud, 

 sand and stones, rocks and ledges.
