ADVANCEMENT OF MARINE SCIENCES 81 



on the coastal hydrography of changes in the rate at which these 

 materials reach the coastal zone. 



6. Study the mechanics and effects of density currents encountered 

 in the coastal area on the current velocities, current patterns, hydrog- 

 graphy, interchange of waters, and rates of sedimentation. 



7. Contract with qualified scientists, research laboratories, research 

 organizations, or educational institutions to undertake basic and 

 applied research studies and experiments in the laboratories and in 

 coastal waters, in furtherance of the purposes of this section of S. 901. 



8. Request and obtain cooperation in these studies from other 

 Government agencies having an interest in the marine sciences and 

 ocean siu-veys, and cooperate with educational institutions and labora- 

 tories devoted to the marine sciences and oceanography, and with 

 other public or private organizations and persons who ma}^ be of 

 assistance. 



Residents and property owners on our coasts are aware of the 

 many changes which constantly can and do affect our shorelines and 

 beaches, frequently causing great financial loss and destrojdng or 

 damaging important recreational areas. In recent years the Beach 

 Erosion Board has conducted research on the phenomena that causes 

 these changes which also have a bearing on oiu* coastal defenses. 



Section 15 of S. 901 would authorize a comprehensive, 10-year 

 program to expand these studies. 



Committee amendments to section 15 

 None. 



SECTION 16 



For the purposes and activities stated in section 15 there would be 

 authorized sums, not to exceed $2 million per annum, for the follow- 

 ing activities: 



1. Investigations m physical oceanography in the near-shore zone. 



2. Purchase, development, acc^uisition, and operation of scientific 

 equipment requned for investigations authorized above, including 

 but not limited to amphibious craft, floating craft, fixed platforms, 

 buoys, current meters, wavemeters, tide gages, sound equipment, 

 direct density measuring equipment, turbulence meters, underwater 

 cameras, and underwater television equipment. 



3. Expansion and equipment of shore facihties necessar}^ to support 

 the investigations authorized in section 15. 



4. Entering into contracts with qualified scientists, research labora- 

 tories, research organizations and educational institutions to conduct 

 physical investigations in the near-shore zone. 



As an example of the need for research and investigations indicated 

 above, a letter from Mr. Richard C Timme, National Marine Con- 

 sultants, Inc., Santa Barbara, Calif., to the committee may be cited. 

 It states in part: 



One immense problem which coastal States must face in 

 the near future is an adequate suppl}' of littoral material 

 (sand) to maintain areas of coastline recreation and struc- 

 tures. The supply of littoral material is dkectly related to 

 the supply of material transported coastward by rivers, trib- 

 utaries, and streams. As these sources are curtailed by dams.
