Institution of Oceanography, Lamont Geological Observatory, and Woods Hole 

 Oceanographic Institution will participate in these investigations. The 

 Navy's support in this area constitutes a substantial portion of the 

 U. S. part of the International Indian Ocean Expedition. 



Other oceanographic institutions have extensive current programs in 

 waters adjacent to their laboratories. For example, the Chesapeake Bay 

 Institute has a program to trace the movement of a fluorescent dye, 

 Rhodamine B, in Chesapeake Bay. This dye can be followed over a 

 10-20 day period permitting the determination of weak current patterns 

 not readily detectable from direct current measurements. Similarly, 

 regional programs will be continued and expanded where possible. 



Numerous programs are underway within institution and industry labora- 

 tories to develop new and better equipment for the measurement of 

 currents and other parameters associated with the physical and chemi- 

 cal variables in the sea. These efforts will be accelerated and the 

 resulting improvements of techniques made available to other labora- 

 tory and agency programs. 



An understanding of turbulent processes is a necessary prerequisite 

 to the development of objective forecasting systems for any of the 

 internal oceanic parameters. The use of Rhodamine B in tracing water 

 particles will be further developed by the Chesapeake Bay Institute 

 primarily to study the estuarine diffusion problems. Lamont Geological 

 Observatory will apply this same technique to deep sea diffusion 

 problems. At the University of Miami and New York University, surface 

 measurements of diffusion will be expanded to include subsurface 

 measurements. 



In addition to the foregoing programs that are concerned primarily 

 with acquiring more basic knowledge about the oceans, there are many 

 programs in the Office of Naval Research devoted to applying this 

 knowledge to Naval problems. These programs, which provide infor- 

 mation for anti-submarine warfare, are also very productive in gaining 

 a further understanding of the oceans, and they will continue in 

 FY-63 with greater emphasis on the effects of the environment. The 

 applied programs are concentrated at the Marine Physical Laboratory 

 and the Applied Oceanographic Group at Scripps Institution of Oceanography, 

 Hudson Laboratories of Columbia University and the Woods Hole Oceanographic 

 Institution. 



Hydrographic Office FY-62 $80,000 



FY-63 $80,000 

 Hydrographic Office research in physical and chemical properties of the 

 oceans is directed toward the solution of military problems. Oceano- 

 graphic data are particularly valuable for military planning and for 

 utilization in forecasting. Emphasis will be placed on three activities: 

 refinement of data collection, especially instrumentation; research into 

 dynamic oceanic principles; and utilization of data for specific military 

 applications.
