This graph, based on a series of 

 water samples collected at the 

 tower in summer, shows tempera- 

 ture (T) and salinity (S) decrease 

 with depth, whereas density 

 (Ot) increases. The Vdisdld fre- 

 quency (N) fluctuates, with the 

 highest values being found in the 

 thermocline. In summer, the sa- 

 linity ranges from 33.75%o to 

 33.96%o. The average year around 

 is 33.60%o. 



Graph reveals the percent of oxygen saturation at one atmosphere and observed tempera- 

 ture throughout one day in July. Note that the oxygen saturation of sea water to depths 

 of 20 feet sometimes exceeds 100 percent.
