toward several parameters such as wind stress over the water, coastal 

 boundary conditions and the effect of bottom topography on currents. 

 With the rapid accumulation of current observations it is becoming possible 

 to verify and modify the theoretical work. 



In order to test theoretical studies, work is being carried out with 

 several experimental models, some of which use rotating basins. While 

 earlier work attempted to model the real oceans, the present trend is 

 to reach agreement between theory and experiment by using simple boundary 

 conditions. The Woods Hole Oceanographic Institution and the University 

 of Stockholm have strong and well-coordinated model investigations which 

 are being accelerated. Results of theoretical and model work are Droving 

 to be extremely valuable in planning field investigations. 



Gross field measurements of the large scale circulation systems will 

 be continued in FY-63? and detailed investigations of individual 

 current systems and of circulation in the deep ocean will receive 

 increased attention. 



The Arctic Research Laboratory of the University of Alaska has developed 

 techniques enabling it to maintain small research stations upon pack ice. 

 This technique permits the establishment of several floating stations 

 throughout the Arctic Basin which should greatly add to our understanding 

 of Arctic circulation. The newly discovered ice island, ARLIS II, will 

 continue to be occupied as long as it remains in an area of interest. 

 Ice island T-3, now in a favorable position, will be occupied. In the 

 Arctic, Lamont's standard oceanographic measurements and geochemical 

 observations are closely coordinated with those of the Arctic Research 

 Laboratory and other groups making geophysical investigations. Also in 

 the Antarctic, Lamont will emphasize the reg'ion proximate to the Antarctic 

 convergence. 



Much of the work will be concentrated in the equatorial regions.. New York 

 University, Texas A & M College, Johns Hopkins University, University 

 of Miami, Woods Hole Oceanographic Institution and the Marragansett Marine 

 Laboratory will participate in the investigation of the Equatorial Atlantic 

 and the region off the west coast of Africa in cooperation with the efforts 

 of the Bureau of Commercial Fisheries and Coast & Geodetic Survey., Deep 

 current work will be carried out in the Atlantic and Pacific Oceans by 

 scientists from the Narragansett Marine Laboratory, Woods Hole Oceanographic 

 Institution and Scripps Institution of Oceanography using new techniques 

 and equipment. Anchored buoys and Swallow floats will play an important 

 role in these measurements . It is anticipated that radio telemetering 

 will be installed on the line of buoys measuring currents between Cape Cod 

 and Bermuda. 



FY-63 will also see the first major effort to observe the Indian Ocean 

 current structure and changes in it caused by shifting monsoon winds.
