conversion program. The input can be a single time series (as ■w(t)), a paired 

 time series (as u(t)^ ■w(t)) from the OMDUM system, -which may or may not be 

 corrected; or a paired time series from the LIMDUM system (as w-, and Wp, or 

 u-]_ and Ug). The usual auto -spectrum analysis is performed on the. single time 

 series. On all paired time series both the auto-spectrum and cross -spectrum 

 operations are performed (as discussed in chapter III). The interpolation 

 program (entitled PROGRAl/I BBELS) is discussed in chapter III. The correction 

 program is entitled SUBROUTINE CORRECT. The third program, the spectrum 

 analysis, is entitled SUBROUTINE SPECTRA. The following abbreviations are used. 



u(l) = Interpolated velocity data from u meter (or upper meter) 



w(l) = Interpolated velocity from vertical w (or lower meter) 



Ml = Number of lags for spectral estimates (limit is set at 100 ) 



CODE = ,^0 denotes single time series 



1 denotes OMDUM data 



-1 denotes LIMDUM data 



101 = Number of series 



y02 = Depth of instrument 



103 = The nth measurement at the particular depth. 



I 



YOU = Time interval (sec) 



U(j) = Un interpolated velocity 



T(J) = Time of occurrance of U(j) velocity. 



NotQ : The CDC 3200 program has a capacity to take 32 x 10-^ single time series 

 data pieces or 2UOO data pairs .
