slides and of their locally generated waves resulting from the Alas- 

 kan earthquake in 1964. 



— On the Continental Shelf of northern California and southern Ore- 

 gon, acoustical, sub-bottom profiling delineated major faults and 

 late Tertiary sediments. Systematic magnetometer surveys have lo- 

 cated concentrations of heavy minerals (some of gold) and of near- 

 shore ancient sedimentary rocks (a common locale of petroleum 

 accumulations). 



— In the Gulf of Mexico, the dynamics of formation and sedimentary 

 healing rates of numerous w^ashover scars inflicted on the Padre 

 Island National Seashore by hurricane Beulah were determined. 



— Acoustical profiling in San Francisco Bay defined the geometry of 

 the sediments in the central part of the Bay and located several 

 hitherto unknown faults, increasing knowledge of the earthquake 

 hazards to urban development of the Bay area. 



2. The Bureau of Mines conducts continuing studies of the United States 

 position with respect to consumption, domestic production, and reserves 

 of more than 80 mineral commodities. The Bureau of Mines also ex- 

 amines the economics of minerals production and acquisition from marine 

 and alternative sources. The marine program of the Bureau is designed to 

 assist in the development of technology for the extraction and beneficiation 

 of marine minerals; and the development of equipment and techniques for 

 sampling and delineation of marine mineral deposits. The Bureau is also 

 concerned with identifying the new technology required for economic recov- 

 ery of materials from the sea. The program, finally, is intended to develop the 

 basis for sound advice on Federal policy concerning ocean mineral leasing 

 and regulation of ocean mining operations. 



The Bureau of Mines works in cooperation with private, educational, and 

 Government organizations to improve economic marine mineral production. 

 The cooperative program is designed to provide an opportunity for com- 

 panies to develop experience in the marine minerals field, crystallize their 

 interests, and determine probable opportunities for their own commercial 

 ventures in the sea through : 



— collecting, assembling, and analyzing oceanographic data pertinent 



to marine mining ; 

 — evaluating and improving techniques for marine mineral sampling 

 and deposit delineation, including participation in research cruises 

 on the Pacific Coast ; 

 — collecting, assembling, and analyzing performance and cost data on 

 dredging and other technology applicable to marine mining. 



3. The heavy metals program of the Bureau of Mines and the Geological 

 Survey, with supporting survey operations provided by the Environmental 

 Science Services Administration and Navy, is directed to stimulating the
