PHYSICAL OCEANOGEAPHY OF THE GULF OF MAINE 



961 



Obviously, the center for the general anticlockwise gulf eddy lay considerably 

 farther offshore in that summer than in 1914 — according to the chart approximately 

 50 miles south of Mount Desert Island. The general drift in the northwestern and 

 western sides of the gulf, then, more nearly paralleled the coast line from northeast to 

 southwest, and so southward past Cape Elizabeth toward Cape Cod. Under these 

 circumstances drifts might be expected more closely to approximate the tracks of the 

 bottles that went from the Bay of Fundy to Cape Cod in 1919 (p. 870 ), rather than 

 to show the offshore trend characteristic of the series set out off Mount Desert and 

 off Cape EUzabeth in the summers of 1922 and 1923 (p. 895).

In August, 1913, no data were obtained closer to the Nova Scotian coast than 

 German Bank; but a higher surface in over the latter than over the basin suggests 

 the northward drift to be expected on this side of the gulf. As it happens, this 

 general scheme is obscured by a rather complex interaction between light and heavy 

 water over the eastern side of the basin, which may, perhaps, mirror nothing more 

 than some observational error at one or other of the two stations concerned (10092 

 and 10093). 



Unfortunately, no observations were taken in the southern or southeastern parts 

 of the area in August, 1913. However, the distribution of salinity (p. 767) makes it 

 probable that the heavy water in the ofSng of Mount Desert was then entirely
