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 ofRng of the channel would have settled this question.
