PHYSICAL OCEANOGRAPHY 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 Elizabeth 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 offing of Mount Desert was then entirely
