Abstract : This report describes a series of computer programs developed at Woods Hole Oceanographic Institution during 1977 to compute scalar bispectra and crossbispectra (BISCAL), rotary bispectra and crossrotary bispectra (BIVEC) and to display corresponding bicoherences (BPLOT) and rotary bicoherences (RBPLOT) as contour plots on the bifrequency plane. The usual method of calculating the bispectrum in the frequency domain after using the Fast Fourier Transform is used here, and so there is a program for calculating the Fourier coefficients (FOURIER) as well as programs for organizing the data (FRAGTAP, ORDAT) or generating artificial series (GENRAN) if desired. There is also one specialpurpose program which calculates line integrals of (scalar) bicoherences in the bifrequency plane along paths of constant = +w1 + w2 to determine the relative total contribution of quadratic interactions to each frequency (BISUM).
