Ketchen, 1978). This buoy followed the main 

 branch of the Labrador Current and traveled 

 south. One year later another BTT buoy, platform 

 I.D. 0647, was deployed very close to the 1976 

 location (Knutson and Neill, 1978). This buoy 

 followed the northeasterly branch. Platform I.D. 

 0731 was deployed further upstream but passed 

 about 10 miles to the west of the 1976 and 1977 

 deployment sites. This buoy followed the Labrador 

 Current south. The mechanism which determines 

 whether drift objects go south or northeasterly is 

 unknown. 



On 28 June BTT 0731 was recovered by the 

 Woods Hole Oceanographic Institution research 

 vessel Atlantis II.
