Fig. 8. Profile of temperature structure. 



TYPICAL TEMPERATURE STRUCTURE PROFILE 



An example of vertical temperature structure 

 of sea water recorded with a thermistor chain 

 off the coast of Mexico is shown in Fig. 8. Here 



each printed line represents whole degree iso- 

 therms. The vertical scale represents depth and 

 descends from the surface to 800 feet. The hori- 

 zontal scale represents both time and distance; 

 in this example either 2k miles or h hours . 

 Hormally this is taken as a distance plot.
