CIRCULATION OF WATER IN BAY OF FUNDY 

 AND GULF OF MAINE 



By Dr. James W. Mayor 



Union College, Schenectady, N. Y. 



A general movement of the water in the Bay of Fundy 

 and its approaches has been shown by investigations car- 

 ried on by the writer for the Biological Board of Canada. 

 During these investigations he has had the cooperation of 

 the staff of the Atlantic Biological Station and especially 

 of Dr. Alexander Vachon who performed the titrations of 

 the water samples and of Capt. Arthur Calder and the crew of 

 the Prince who set out all the drift bottles and made all hydro- 

 graphic observations. 



Three different and independent methods have been 

 applied to the problem: The actual measurements at dif- 

 ferent points made with current meters by Dr. W. Bell Daw- 

 son have been treated mathematically so as to eliminate 

 the semi-diurnal oscillations of the tidal stream; a large 

 number of drift bottles have been set out; and lastly, 

 a series of hydrographic sections have been made in the 

 bay, and from the temperatures and salinities at the dif- 

 ferent stations the velocities at right angles to the sections 

 have been calculated by the hydrodynamic method devel- 

 oped by Bjerkan. 



During the summers of 1904 and 1907, Dr. W. Bell 

 Dawson,* of the Dominion Tidal Survey, made an exten- 

 sive series of accurate observations on the currents in the 

 Bay of Fundy and its approaches, using the surveying 

 steamer Gulnare and anchoring at 19 different stations for 

 periods varying from two days to one week. Measure- 

 ments were made half-hourly with current meters working 

 at a depth of 3 fathoms. The results of these observations
