the Equator to the Icelaud-Faeroe-Greenland Ridge (which divides the 

 Atlantic Ocean from the Norwegian Sea). Approximately 600 observa- 

 tions (Fig. 17) were found after a search of all data up to 1950 and much 

 of the data up to 1954. (The "Bulletin Hydrographique" is 5 to 6 years 

 behind in publication.) Since the temperature at intermediate depths is 

 of interest to the cable engineer onl}^ to the extent that he can use it to 

 determine l^ottom temperatures, the observations in depths greater 

 than 2,000 meters which lay within 100 meters of the bottom were 

 sorted out. Only about 150 observations (Fig. 17) were found in this
