 sinking is accompanied by the process of cabbeling and mixing with 

 the border of the westward-flowing branch of the comparatively warm, 

 salty, West Greenland Current; just as such cabbeling, mixing and 

 sinking takes place on the Labrador Sea side (southern) boundary of 

 this current. Both factors combine to produce a temperature max-

 sized again, that this cabbeling, mixing, and sinking takes place all 

 along the boundaries of the more rapidly moving currents of the cir- 

 culatory system of the Labrador Sea and is not restricted to any single 

 locality. Thus the temperature maximum shown in figure 56 should
