FOREWORD 



In the Atlantic Undersea Test and Evaluation Center (AUTEC) 

 development program, the Naval Underwater Ordnance Station (NUOS) is 

 responsible for the design, installation, test, and evaluation of an 

 underwater weapons tracking range . In order to provide accurate 

 tracking data on test vehicles, the information obtained by the 

 underwater instrumentation must be correlated with the oceanographic 

 environment. NUOS, in a cooperative effort with the Woods Hole 

 Oceanographic Institution (WHOl), obtained water current data during 

 February and March 1963, using the parachute drogue system in the 

 Northeast Providence Channel and Tongue of the Ocean, Bahamas,, 



This preliminary report describes the purpose of the cruise, 

 the drogue system, and the type of navigation used in tracking 

 the drogues. The raw data are included in the Appendix. Analysis 

 of the data will be the subject of a subsequent report. This work 

 was accomplished under BUWEPS Task Assignment Nos. RUT0-3E-000/219 

 l/SF-099-03=02 and ASW Oceanographic Research RU22-2E-000/219 

 l/R00i|-03-01.
