seismic., gravity, magnetic and thermal investigations receive both 

 direct support and indirect support in the form of ship construction, 

 modification and operation. During the numerous cruises and expeditions 

 sponsored by the National Science Foundation, many geophysical measure- 

 ments are taken. An example of this is the geophysics program supported 

 by the Foundation and conducted by Scripps, Lamont and Woods Hole .
