This data record is used to define the random seed for a wave spectrum. It must be before the spectrum to which it applies. Default seed values are defined below.

Within a spectral group, the default values of SEED for each spectrum will be:
If there is no SEED data record or the SEED number is set to 0:
where I represents the i-th spectrum.
If a SEED data record is used for some but not all of the spectra:
where
N_SEED is the number of SEED data records defined in this group J ranges from 1 to the number of spectra which do not have a SEED data record The seed number of a Gaussian integral wave direction of
spread seas:where
I_SEED is the starting seed number of the spread seas J ranges from 1 to the number of Gaussian integral points The seed number of a sub-direction of a user-defined carpet wave spectrum:
where
I_SEED is the starting seed number of the user-defined carpet wave spectrum J ranges from 1 to the total number of user-defined wave sub-directions
