bottles and transporting, free-floating buoys. The Bureau's laboratory 

 in Washington, D. C, is preparing monthly Atlantic coastal and offshore 

 sea-surface temperature charts for the peri del of 1953 to the present. 

 Research presently underway will be continued by the Bureau during 

 FT-63 and in addition new programs will be commenced which will contribute 

 significantly to knowledge of physical and chemical properties of the 

 oceans, A biological and physical oceanographic investigation of the 

 tropical, equatorial Atlantic and West African coastal and offshore 

 waters will commence in the spring of 1963. Objectives of this program 

 are to describe the extent of fishery resources in the equatorial Atlantic, 

 to relate distributions of fish populations to environmental conditions 

 and to contribute knowledge on physical attributes of Atlantic waters. 

 It is planned that this program be a cooperative effort with the Navy, 

 Coast & Geodetic Survey, Bureau of Commercial Fisheries and several 

 private oceanographic institutions. 



Oceanographic research in the eastern tropical Pacific is to "be increased 

 to define zones of high biological productivity. Areas of nutrient 

 enrichment through upwelling and mixing along current boundaries will 

 be sought. Thermocline topography and changes within the mixed layer 

 will be studied. Monthly charts of sea-surface temperatures which the 

 Bureau is now preparing for more northerly waters will be extended to 

 at least 10 o S. latitude and offshore to 100° or 110° W. longitude, 

 depending upon availability of data from merchant ships and fishing 

 vessels. 



Since many of the marine research programs of the Bureau require data 

 over a series of years before results are meaningful, much of its 

 research on physical and chemical properties of the oceans during FY-62 

 will be continued into 1963 • A follow-up expedition into the equatorial 

 Atlantic is planned for the latter part of calendar year 1963 y and 

 oceanographic studies in the eastern tropical Pacific will be continued. 



In addition to these programs of research, it is realized that there is 

 a need for greater, amounts of biological, chemical and physical oceano- 

 graphic data collected in time series over wide expanses of the oceans. 

 Such data will provide clues to changes in the ocean climate to which 

 fish respond. Therefore, an expansion of research is proposed which 

 will monitor environmental conditions. Quarterly biological and 

 oceanographic surveys are to be started in New, England waters of the 

 Atlantic . 



The Bureau proposes to investigate the trade winds zone of the central 

 Pacific to determine principles and parameters of climatic oceanography 

 in this area which are of great interest for fisheries^ weather, 

 navigation and national defense. The objective is to be attained by 

 determination of the seasonal rates of change of surface temperature, 

 salinity, depths of the mixed layer and currents as they are related 

 to the physical processes of heat exchange across the sea surface.
