in figures 21+ and 25. In each figure the graph at the left indi- 

 cate's the percentage of the total observations which showed the 

 mean depth of the thermocline at each of the depth categories and 

 the graph at the right indicates the mean amplitudes plotted 

 against each of the depth categories. It is evident that there is 

 a direct relationship between the mean depth about which the 

 thermocline is oscillating and the amplitude of the oscillations 

 themselves. It will be noted that variations from a straight 

 line relationship exist. In particular it was noticed that the 

 slight decrease in the amplitude at the greater depths shown in 

 the right-hand graph of figure 2^ was also characteristic of 

 some of the data computed for other areas of the ocean but not 

 presented in this report. It is not known at present whether 

 this is due to the relatively few observations taken where the 

 thermocline was found at the greater depths or whether there is
