TM No. 327 



FOREWORD 



In the Atlantic Undersea Test and Evaluation Center 

 development program, the Naval Undervater Ordnance Station 

 (NUOS) Is responsible for the design, installation, test 

 and evaluation of an underwater weapons tracking range. 

 For greater accuracy, tracking data on test vehicles must 

 be correlated with the oceanographic environment . In 

 cooperation with the Woods Hole Oceanographic Institution, 

 NUOS obtained water current data during February and March 

 1963 in the Northeast Providence Channel and the Tongue 

 of the Ocean, Bahamas „ 



A preliminary report (TM No, 306 dated September 19^3 ) 

 described the purpose of the cruise, the parachute drogue 

 system employed, and the navigational equipment used in 

 tracking the drogues, TM No. 306 also included the raw 

 data obtained on the cruise . 



This final report presents an analysis of the data 

 with emphasis on such factors as deep water motion, eddy 

 motion, and current shear. This work was accomplished 

 under BUWEPS Task Assignment No. RUTO-3E-OOO/219 1/SFOO9- 

 03-02 and ASW Oceanographic Research RU22-2E-000/219 

 l/R00i4-03-01.
