in terms of the total degrees of freedom (TDF) to a high degree of 

 accuracy since the total degrees of freedom are large. 



The corrected variance, the significant height, and the 

 total degrees of freedom are relatively insensitive to changes in the 

 noise level and in the high frequency behavior of the spectrum. 

 However, the average period can properly be viewed with caution. 



The winds near the ship at the time of observation are 

 also given to the nearest five knots as read directly from weather 

 maps. These values are subject to later correction in terms of the 

 logs of the weather ships. 



Explanation of tables and graphs 



The body of this report consists of supplementary tables, 

 of tables that give the appropriate results for each of the original 

 wave records, and of graphs of each of the estimated spectra along 

 with the confidence intervals on the spectra. 



The supplementary tables consist of Tables 1 through 4. 

 Tables 1 and Z have been described above. 



Table 3 gives either the on station position of the ship, 

 A, I, J, or K, or the latitude and longitude of the ship if it is going 

 on or off station. The speed and direction of the ship is given.
