NATIONAL OCEANOGRAPHIC PROGRAM—1965 
Program 
Geological-geophysical exploration, 
under Dr. R. L. Fisher. Emphasis on 
two-ship seismic refraction work 
between Darwin and Jakarta. 
Same program, except for seismic 
refraction. Emphasis on heat flow, 
large-volume water-sampling; 
topography. 
Same

In addition, some seismic reflection shooting was carried out, occasional air samples were 
taken, gravity was measured in ports of call; rocks and biological specimens were collected in ports 
of call; and large organisms were dip-netted at light lures on most night stations. 
The second Scripps cruise, called LUSIAD, is also being carried out by the R/V ARGO, accord-
