Figure 3-6. Typical Wave Spectra from the Atlantic Coast.
The ordinate scale is the fraction of total
wave energy in each frequency band of 0.011
Hertz, (one Hertz is one cycle/second) . A
linear frequency scale is shown at the bottom
of each graph and a nonlinear period scale
at the top of each graph.
