swells. Figure 25 indicates that the values of wave heights for particular 

 states of the sea are greatly scattered and variations are as follows: 



State of the Sea 



Wave height meters 



OolO - lo50 

 0=20 - 1.75 

 0.30 - 2o00 

 0.75 - 3oO0 



If, on the other hand, one omits those cases where swells were present 

 then the ranges of v/ave heights for different states of the sea overlap 

 to a much lesser degree. One thus obtains from figure 25 for wind waves 

 without swells, a revised tabulation:

These relations cannot be applied to the estimates of other observers, 



Arithmetic mean values were found from all wave heights at 

 different states of the sea; they were observed during the winter at 

 fixed positions of the lightships. The resultant mean wave heights 

 are shown in Table 2 below and presented in figure 26.

It is evident here (figure 29) as in the frequency diagrams 

 that in the case of the higher values, the wave heights reported from 

 lightship AMRUNBANK were greater than those reported from li^tship 

 BPRKUMRIFF. At each individual state of the sea, -the mean wave heights
