A HYDROGRAPHIC SECTION OF THE BAY OF FUNDY IN 1914. 



By E. Horne Craigie^ University of Toronto. 



(With 1 Chart and 5 Figures.) 



In addition to the hydrographic investigations in the St. Croix river and Passa- 

 maquoddy bay, which have been described in a separate report, it was felt that much 

 might be gained from a similar inves1;igation of the Bay of Fundy itself. Under the 

 existing conditions very much of such work could not readily be carried on, and lack 

 of time necessarily made the observations very limited, but during the last week of 

 August a cruise was made across to St. Mary's bay. Nova Scotia, on which it was 

 found possible to make sufficient observations to form one complete section across 

 the bay. To add to the value of the work, one of the members of the staff took 

 plankton samples at each station. A few observations of the surface temperature 

 were also made between the stations. These are recorded in the table of data obtained, 

 but were not sufficient for any deduction to be made from them. 



The apparatus uged in this work was exactly the same as that which has already 

 been described in the report on the work in the St. Croix river and Passamaquoddy 

 bay, as were all the methods employed. The weight used for sounding was twenty- 

 two pounds. On account of the depth of the water, observations were made only at 

 10-fathom intervals instead of at 3-fathom intervals as was done in the previous 

 investigation, except at the two deeper stations in the Western passage. 



Temperature curves for each station and an isothermal section of the bay havo 

 been constructed. For convenience of comparison the section has been drawn upon 

 the same scale as the accompanying map, upon which the stations are shown. 



The stations were established upon a straight line drawn from East Quoddy 

 head, Campobello island, to Boars head, Petit passage, Long island, Nova Scotia, and 

 were located as follows : — 



The distances are geographical miles. The points were found by the use of a log. 



The 50 fathom and 100 fathom lines have been inserted upon the map, which thus 

 gives an idea of the conformation of this part of the bay and shows how the stations 

 were established so as to obtain as complete a sedtion as possible, showing conditions 

 in the various parts. Station 1 is in the Grand Manan channel, which will be noticed 

 to rise to less than 50 fathoms a little further out, while station III has been placed so 

 as to show the conditions in the deepest part, where the depth is over 100 fathoms. 



The temperature curves (see figure) are interesting in that they show a marked 

 resemblance between stations II, III, and IV, while station I in the Grand Manan 

 channel is distinctly different. Considerable areas of the same, or nearly the same,
