or biological factors. Further refinement of methods of studying 

 the deep sea scattering layer could provide knowledge of the ocean 

 food potential and of circulatory studies important in radiation 

 contamination. 



Other important instrumentation needed for development are 

 accurate electronic measuring devices for geodetic distance 

 measurements, offshore water level measuring equipment with 

 recording and telemetering links to remove the uncertainty of the 

 tidal gradient between the survey vessel and the tide gauge ashore, 

 means for studying seismic sea waves, and an early warning system 

 for destructive seismic waves. 



Time does not pernnit a detailed discussion of all the ways in 

 which industry can contribute to man's knowledge of the oceans, 

 therefore, only nnajor areas for profitable research development 

 have been mentioned.
