3. Evaluations of the newly developed spectral form, the various new 

 machine programs for integrating ship observations with an initial guess 

 regression wind, for handling wave growth and decay, for specifying the 

 wave spectrum at high frequencies, and for interpolating between 12- 

 hourly observations all show that the results agree with observed wave 

 spectra within the expected accuracy in view of the many variables in- 

 volved. This is not to say that further improvement is impossible 

 because there is still much work remaining to be done. It is believed 

 that the 15 months of wave spectra which have been obtained for 519 

 points over the North Atlantic Ocean represent a definite step forward 

 and the machine techniques used in obtaining these data are a break- 

 through in this field of endeavor.
