any contouring would be performed manually. 
Parameters other than depth could be similarly 
plotted in this mode. 
CONCLUSION 
In conclusion, I have described a digital 
data processing and display instrument of rather 
broad capabilities as an example, if you will, of 
the tools which modern-day technology is making 
available to scientists working in oceanography. 
I have attempted to relate certain character- 
istics of the instrument, such as precision, 
real-time reduction, flexibility, and functional 
completeness, to similar requirements which 
seem to me to be pertinent to the oceanographer's 
task. And finally, I have shown two elementary 
examples, and there are many more, of how such 
an instrument could be put to work in a very 
practical sense, relieving the scientist of much 
of the burden of his own data reduction. 
ACKNOWLEDGMENT 
I would like to acknowledge the efforts of the 
many people whose individual skills and hard 
work are represented collectively by this 
instrument; in particular, the contribution of 
D. M. Scott of the Westinghouse Electronics 
Division, under whose supervision the digital 
computer was designed and built.
