 revision to 



End: (1) Supplement to H.O. Pub. 60? 



1. The value of oceanographic information is dependent upon the accuracy 

 and reliability of the instruments used for its collection. The Instruc- 

 tion Manual for Oceanographic Observations (H.O. Pub. 607) provides a 

 basic reference for the care and handling of selected oceanographic instru- 

 ments. Closely allied with this information is the need to know more about 

 the actual performance of oceanographic instruments that have been tested 

 under controlled environmental conditions . 



2. The results of tests conducted by the Navy's Oceanographic Instru- 

 mentation Center have been synopsized and incorporated in a prototype 

 Instrument Fact Sheet. Enclosure (1) should be beneficial to all activ- 

 ities that use precise oceanographic instruments or are concerned with 

 the validity of the data derived from them. Other fact sheets will be 

 prepared and distributed as instruments are tested and evaluated by the 

 Center . 



3. Comments and suggestions concerning the use of the Instrument Fact 

 Sheet are invited and should be forwarded to the Commander, U. S. Naval 

 Oceanographic Office.
