Track F near the northern Grand Banks was mainly governed by the 

 Labrador Current. The few survivors that reached the northeast 

 slope of the Grand Banks drifted to the northeast and out of the main 

 branch of the Current. The prevailing soutliwesterlies, while light, 

 apparently had sufficient driving force to accomplish the above and 

 possibly the Labrador Current, salient to the northeast in this region.
