figure 16, developed into interlocking high and low meanders in 

 figure 18. One of these, developing westward along the 44th parallel, 

 was accompanied by a greater eastward diversion of Labrador Cur- 

 rent water in the lower dynamic heights northward of that latitude. 

 The high meander, centered at 46° N., on the eastern edge of the 

 second survey, developed westward and was centered at about 

 45°20' N., in the third survey. 



Figure 19, representing the dynamic topography found during the 

 fourth survey, shows in greater detail the pattern of diversion of 

 Labrador Current water eastward north of Flemish Cap and south- 

 ward east of Flemish Cap. From the standpoint of berg mortality it 

 is worthy of mention that in this survey the minimum temperatures 

 in the cold core of the Labrador Current were uniformly about 

 — 1.5° C at all sections over the slopes of the Grand Banks, but the 

 minimum temperatures in the cold core of the water in the eddy 

 around Flemish Cap were about 2.0° at the periphery and about 3.5° 

 at the center.
