65 and 67 but not in between. In 

 botti cases, this ttiin and narrow 

 cold-water core was immediately 

 adjacent to NAC water. The 

 radius of the bend suggested in 

 the hydrography is a function of 

 the north/south station spacing (18 

 km), but it is approximately the 

 same scale as the buoy track 

 radius. The hydrographic section 

 was taken three days after the 

 buoy passed through the area. 

 This probably explains the fact 

 that the location of the bend in the 

 buoy track and the zero degree 

 water are not coincident. 



The orientation of the SLAR- 

 obsen/ed striations in the 26 April 

 imagery (Figure C-14) north of the 

 front is coincident with the direc- 

 tion of the buoy motion and the 

 location of the Labrador Current 

 as determined by hydrography. 



None of the buoys deployed along 

 the westernmost hydrographic 

 section moved through the survey 

 area, so their trajectories (Figure 

 C-14) are of limited use. Buoy 

 4536 was deployed with its 

 drogue in Labrador Current water 

 alx)ut 4 km from a location that 



buoy 4542 moved through 48 

 hours earlier; however, while buoy 

 4542 moved rapidly to the east 

 north of the eddy, 4536 moved 

 sluggishly (20-30 cm/s) to the 

 southwest , roughly parallel to a 

 front shown on the 26 April 

 imagery. Its subsequent north- 

 westward movement was approxi- 

 mately parallel to the striations 

 recorded by the SLAR four days 

 earlier. There is no supporting hy- 

 drography, so it cannot be deter- 

 mined if the subsequent south- 

 ward buoy nnotion along the 

 1 000m bottom contour of the 



Figure C-9 Sea surface (0.5 - 1.0m) temperature (°C) distribution based on the first phase (27 April — 

 3 May) hydrography.
