The research programs supported by the National Science Foundation 

 and the Navy at institutions and universities produce quantities of data 

 which are often useful in the production of charts and atlases. Those sur- 

 veys which are particularly oriented to defense systems, resource develop- 

 ment, and other end-uses are described in detail in other chapters of this 

 report. Of the multipurpose surveys undertaken during 1969, the following 

 were of major interest: 



1. ESSA continued its surveys of the U.S. coast and the deep ocean, con- 

 centrating its efforts off New England, North and South Carolina, Puerto 

 Rico, Washington, Alaska, and the Hawaiian Islands. Special attention was 

 given to inshore hydrographic investigations along the Atlantic and Gulf 

 coasts, where demands for small-craft charts are rapidly growing. Because 

 of extensive changes in the marine topography and possible navigational 

 hazards resulting from hurricane Camille, selected areas of the Gulf coast 

 were resurveyed and recharted. The SEAMAP project involving acquisition 

 of bathymetric and geophysical data continued in the northeast Pacific. 



2. ESSA published seven new nautical charts and issued 487 corrected 

 editions. In consultation with the Department of Defense, ESSA released 

 several previously classified Alaskan charts for public use. A bathymetric 

 map, with two geophysical overlays, was published for Norton Sound, and 

 two other bathymetric maps were published for the California-Oregon coast. 

 Bathymetric maps are also being prepared for parts of the Gulf of Maine 

 and off-shore regions along the North Carolina coast. 



3. Instrumentation to measure waves in the tsunami spectrum in the open 

 ocean was developed and tested by ESSA. 



4. The Bureau of Commercial Fisheries continued its extensive surveys and 

 monitoring of oceanographic conditions, concentrating its work on the East- 

 ern Bering Sea, Aleutian Island area. Gulf of Alaska, Hawaiian Islands 

 area, Eastern Pacific Ocean, the Caribbean Ocean, and the areas off Florida 

 and the New England coasts. 



5. The Bureau of Commercial Fisheries published an oceanographic atlas 

 of the Pacific Ocean. Summarizing 50 years of work, it is based on 50,000 

 oceanographic stations and 3 million individual observations. Because of 

 fishery implications, it is primarily concerned with the uppermost mile 

 of water. 



6. The Navy produced 110 new charts for general navigation, 67 special 

 charts for surface fleet and submarine use, over 700 corrected charts, and 

 numerous accessory publications. Of particular note is the Navy's production 

 of 87 new charts based on surveys and charts made by other countries, the 

 materials for which were acquired through the bilateral chart reproduction 

 exchange program. 



7. The Navy conducted a major survey of the Pacific Trust Territories at 

 Palau, Ulithi, Truk, and Ponape, along with other investigations in the 

 Western Pacific and the Hawaiian Islands. The first third of a 3-year coastal 

 survey of South Korea was also carried out. Deep-ocean bathymetric and 

 geophysical surveys were conducted in the North Atlantic, Western Pacific, 

 and off both coasts of the United States collecting almost 500,000 miles of 

 bathymetry and geophysical data.
