Detailed investigations cf the energy exchange processes between at- 

 mosphere and ocean have already been carried out on Texas Towers. 

 Advanced instrumentation developed from these studies will be used 

 on Argus Island, the research tower located off Bermuda, This station 

 will provide the data required to establish new empirical relation- 

 ships and to test theoretical relationships between the ocean and 

 atmosphere. In FY-6.3 an oceanographic research ship will be instru- 

 mented to provide a deep-water research operation of the Argus Island 

 type . 



An oceanographic aircraft is now being outfitted and will be available 

 for long-range survey. It will be capable of providing data such as 

 sea surface temperature, bathythermographs, ocean wave records and 

 supporting meteorological data, 



A synthesized mathematical model of equations suitable for short-range 

 sea water temperature structure forecasting have been reduced for 

 tabular, nomogram and computer usage. Short-range forecasting tech- 

 nique research will be further developed and extended to longer range 

 and seasonal outlooks, 



Changes in thickness of the isothermal layer cannot always be related 

 to meteorological and oceanographic activity at that location. Large- 

 scale movement of surface and subsurface water appears to show direct 

 relationship to atmospheric circulation. The problem will be ap- 

 proached from both the synoptic and the longer term climatological 

 points of view. Additionally, a purely statistical approach to the 

 problem will be conducted on an ocean-wide basis* A grid of predicted 

 meteorological and oceanographic factors and extrapolation in time 

 and space.. Special research into this phenomenon will be conducted 

 aboard ocean station vessels. Hydro survey ships and other ships as 

 practicable. Radio telemetering oceanographic buoys will provide 

 additional ocean coverage with repeated observations from fixed loca- 

 tions. 



Research will continue toward a better understanding of surface waves 

 and wave-induced sea floor pressure fluctuations: This effort will 

 include directional spectrum analysis and correlation of surface and 

 bottom pressure records, as well as work on prediction techniques. 

 Continued importance will be placed on spectral analysis of many 

 physical parameters. Empirical and semi-empirical wave models will 

 be studied which will include examination of varied wind conditions 

 (velocities, durations -and fetches). 



Within arctic regions the physical processes covering the behavior of 

 the environment become increasingly complex, Here three distinct 

 layers - atmosphere, cryosphere and hydrosphere - interact. Frictional 

 forces at the air-ice and ice-water interfaces are the primary influences 

 in producing ice movements, A major study effort will be directed at
