*2 min. for C-MAN; 8 min. for moored buoys
**20 min. for moored buoys and 14 min. for C-MAN. The three Olympic buoys and 41023 had 9 min. averaged waves. Directional waves utilize the WPM.
***Whichever is greater.

Wave heights of less than 0.25 m are reported with zero height and period. Frequency resolution on some wave measurement systems can vary from 0.005 Hz at low frequencies to 0.02 Hz at high frequencies. See Column Headings or Labels in the Raw Spectral files to identify the center frequency of each band.
§Some stations average over a 40-minute period and some other over a 20-minute period.
