appendix A. Table 3 is a summary of the drogue data obtained along T2, The 

 depths at which drogues vere tracked were the same as the depths along Tl. 



Table 3= Summary of Drogue Data - Transect 2 



Current speeds along T2 were generally less than those obtained along Tl. 

 Directional motion was also markedly different. 



Motion at 10 and 200 meters was southwesterly (into the Tongue)^ and the 

 drogue tracks indicate uniformity with respect to speed and direction (figure 

 7), Drogue Foxtrot (lO meters)^ however^ did not conform with the others. 

 Position fixes indicated that the Decca receiver was not operating properly. 



The tracks of drogue 3-II (lO meters), and of Mike and Romeo (both 200 

 meters) indicated a displacement (in the form of a hump) toward the north from 

 a relatively uniform path (figure 7), This displacement occurred on all 

 three drogues at the same time. The displacement began on 22 February at 

 0500 hours and continued until 0200 hours on 23 February, This motion did not 

 appear to be tidal in nature, but fixes on the individual drogues were too 

 far apart in time to substantiate this. 



Motion at 10 and 200 meters was uniform and toward the Tongue, as was the 

 case with the 10 and 200 meter drog^jes along Tl, The water motion at these 

 depths is probably due to a combination of flow through the Northeast and 

 Northwest Providence Channels. (The sill depth in the Northwest Providence 

 Channel is approximately 66O meters [preference 2}; therefore, there can be no 

 contribution of flow from the Northwest Providence Channel at depths greater 

 than about 66O meters in both the Tongue and the Northeast Providence Channel.)
