PHYSICAL OCEANOGRAPHY OF THE GULF OF MAINE 
789 
The course of the isohaline of 32.5 per mille over Georges Bank in this profile 
is also worth comment in connection with the northeastern to southwestern tongue 
of low salinity and low temperature recorded there at the surface (p. 770) as evidence 
of a counter movement out of the gulf, eddying clockwise around the eastern end of 
the bank (fig. 207) . The confinement of the slope water between the banks is also 
illustrated by a summer chart of the 34 per mille water (fig. 152), as is its extent at 
that season compared with the spring (fig. 118).
