TM No. 306 



Since this is a preliminary report, only raw data and descriptions 

 of the equipment and procedures are presented. A subsequent report will 

 include a final analysis of the data in an attempt to answer the following 

 questions: 



1. Can the motion of the water in the Northeast Providence Channel 

 be traced to the motion of the water in the Tongue of the Ocean (TOTO) 

 (or vice versa)? 



2. What is the "mixing length" of the predominant eddies in TOTO? 



3. What is the general magnitude and intensity of the horizontal 

 and vertical current shear in the central region of TOTO? 



4. To what extent (and time scale) are turbulent shears (normal 

 to the bank walls) causing mixing and transport of bank water into the 

 AUTEC region? 



5- How is the wind drift pattern related to tidal data?
