circulation. The explanation of disagreement may lie in a sudden 

 and transitory outpush of water from between the Grand Bank and 

 Flemish Cap. The shape of the stream lines on the inner side of the 

 Gulf Stream in this locality suggest such a possibility. 



SUMMARY 



The five current surveys which were made of the waters around the 

 Grand Bank beginning the first week in April and ending the latter

part of June (and the five sets of illustrations, figs. 33-52) permit 

 us to follow quite accurately the changes in the general circulation 

 which took place during the ice season of 1927. 



When the patrol vessel first entered the ice regions the circulatory 

 system was basically normal, and by that is meant, Labrador current 

 flowed southward along the eastern edge of the Grand Bank, while 

 offshore the. Gulf Stream moved eastward in the Atlantic. The 

 countercloc'kwise eddy that the patrol has so often observed centered 

 over the.sbuthwestern slope of the Grand Bank was sounded out and
