PHYSICAL OCEANOGRAPHY OF THE GULF OF MAINE 
709 
offshore gales often bring up water from below in volume great enough appreciably to 
affect the temperature and salinity of the surface along the western shores of the 
gulf during the later spring (p. 729). 
It is not clear whether the water salter than 32.8 per mille, which occupied the 
southeastern part of the gulf in March, 1920, was then continuous with still higher 
salinities offshore at the 40-meter level, as is suggested on the chart (fig. 93), or 
whether it was inclosed by slightly lower salinities at the mouth of the Eastern 
Channel, as seems to have been the case at the surface at the time. A station in 
the offing of the channel would have settled this question.
