CHARACTERISTIC TYPES OF CIRCULATION AT JUNCTION OF LABRADOR 



Current and Gulf stream 



FiGUKE 101. — The two iipper maps and the lower left one feature a cyclonic vortex 

 ill the circulation at the Tail of the Grand Bank, where the Labrador current 

 meets the Gulf Stream. The lower right-hand map shows the Gulf Stream crowa- 

 ing well in over the southwest slope of the Grand Bank, while a strong Labrador 

 current penetrates deeply toward the south. All these types of circulation have 

 been mapped by the ice patrol, and icebergs alst> have many times been observed 

 in the control of these systems.
