Salinity (Fig. 20) and temperature ranges at this level were 

 considerably less than those in the upper levels.

 (Figs. 



500-meter level : The shapes of the isotherms and isohalines 



21 and 22) were similar in many respects to those in the 200 

 meter level, but conditions were much more uniform. Again, all temperatures 

 were greater than 0°C indicating that the Arctic Bottom Water lay 

 below this depth throughout the survey region when the 1964 EDISTO 

 stations were occupied.
