the northbound current, and in fact included about 1.0 milhon cubic 

 meters per second of northward-moving water. Tlie tabulated 

 transport values should therefore be increased by about 1.0 for both 

 sections NW. and SE. to obtain the transport of the Labrador Current 

 for the fourth survey. Thus the transport was about normal at these 

 sections and about 0.4 above normal at section SW. The proportion 

 of the total Labrador Current following the eastern branch was 78 

 percent, which is below normal for this time of year. At the time of 

 the postseason cruise the volume transport had dropped to values 

 even smaller than the supposed normals for the time of year. 

 Although the proportion of the total Labrador Current flowing in 

 the eastern branch normally decreases seasonally, it increased in 1954
