Gulf Stream current meandering pattern and eddy 

 development during a one-month period 



The Gulf Stream study is a long-range program, involving 

 participation of several Navy in-house and academic groups 

 as well as other federal agencies. The program is aimed at con- 

 tributing not only to a better description of ocean currents but 

 also to theoretical and laboratory studies. The theoretical de- 

 velopment of models of ocean circulation actually needs to be 

 augmented by more refined field experiments, and such experi- 

 ments are being developed. The necessary instrumentation is 

 being evolved. Simultaneously, investigations of the modes of 

 motion in ocean waters, the time and space scales that contain 

 significant kinetic energy, and the coupling of various modes 

 and scales of motion are being pursued. This aspect of the 

 program is in its early stages of investigation, and results from 

 it are expected to contribute substantially to the prediction of 

 current movements which affect navigation and the emplace- 

 ment of naval systems and equipment in the ocean environment.
