survey, figure 15, shows a weak Labi-ador Current whicli becomes 

 poorly defined south of 45° N. Most of what Httle Labrador Current 

 water enters the surveyed area from the north sets westward between 

 45° X., and 46° N., and is lost to the surveyed area. The higlier 

 dynaiuic heig'hts ;it stations 7622, 7()2;^, and 76)30 are the resuU of 

 warmer water which probably crossed the Grand Banks Irom the 

 margins of the Gull' Stream system oil" tlie southwest slope of the 

 Grand Banks. Some modified Labrjidor (^u'rent water continues in a 

 southwai'd flow along the eastern slo])e of the banks south of 45° N., 

 and rounds the Tail of the Banks to the westward in a normal pattern. 

 The Atlantic Current shows a characteristic meander to the southeast- 

 ward ill the vicinity of station 7608. The northern nuirgin of the 

 Atlantic C/urrent shows an abnormal meander northward, with the 

 axis at a])Out 46° W., the efi'ects of which extend to the northermost 

 section of the survey at station 7667. Eastward of this meander, a 

 cyclonic eddy is shown southward of Flemish Cap. Any bergs enter- 

 ing the area from the north would ])rob<ibly liave been set westward 

 onto the baidvs north of about 45°;30' N. 



Figure 16, representing conditions found during the second survey, 

 shows eddies and meanders in the southwestern part of the surveyed 

 area which indicat(> that for a berg to be carried soutli by the Labrador 

 Current, it would have liatl to enter the western edge of the area 

 between stations 7725 and 7726 and even then with some chances of 

 stranding on the northern odix^" of tlie Grand Banks. The weak 

 clockwise circulation within the two dynamic isohypses of 970.9 

 dynamic meters northwestward of Flemish Cap was probably con- 

 ditioiTcd by the northward meander of the Atlantic Current found in 

 this longitude in the first survey. Rather flat topography was found 

 in the northeastern half of the surveyed area. 



In figure 17, from data collected dui-ing the third survey, the Lab- 

 radoi- Current shows some recovery from the situation found during 

 the first survey, especially with regjird to its continuation southward 

 past the 45th parallel. It suft'ers some eastward deflection at the 46th 

 parallel and just north of the 44th parallel the renmants of the warm 

 water found during the first survey still afl^ect stations 7768-70. 

 Losses of Labi-ador Current water mixing and recurving eastward are 

 l)ronounced south of 44° X. A major meander of the Atlantic Cur- 

 rent northward with its axis along the 47th meridian is shown from 

 43° X., northward. Eastward of this a southward meander of colder 

 mixed water extends along the 46th meridian to south of 44° N. The 

 remnant of the abnormal northward Jiu^ander of Atlantic (\nTent 

 water found during the first survey along the 46th meridian is traceable 

 with an axis through stations 778:5, 7800, and 781 1. 



The dynamic to])ograpliy found during the fourth survey is shown 

 in figure 18. The dividing point between the eastern and western 

 branches of the Labrador Cun-ent appears to ])v som(^what northward
