Abstract 



Airborne surveys were conducted monthly from August 1963 through 

 July 1968, using an infrared radiometer to measure sea surface tempera- 

 tures and to develop isotherm charts depicting temperature ranges for 

 three areas of the eastern Pacific Continental Shelf. A total of 179 airborne 

 surveys were conducted from aircraft made available by the U.S. Coast 

 Guard as part of their commitment in support of the national oceano- 

 graphic program. Sea surface temperatures determined by the monthly 

 surveys are presented in contoured charts. Five-year mean sea surface 

 temperatures for each of the three survey areas were determined for each 

 calendar month of the year by 10-minute longitude by 10-minute latitude 

 areas and isotherm charts were drawn from these data. 



The mean difference between 146 simultaneously observed airborne 

 radiometer and surface bucket temperatures was —0.35 F° (radiometer 

 lower) . The standard deviation was 0.65 F°.
