REPORTING 

 PROCEDURE 



A printed form NHO-n92 for re- 

 cording shipboard observations has 

 been prepared to standardize the 

 items to be recorded and the man- 

 ner in which they are to be re- 

 corded. These forms may be pro- 

 cured from the U. S. Navy Hydro- 

 graphic Office, Washington 25, 

 D. C. 



So that the data which you collect 

 can be analyzed by an IBM ma- 

 chine, the values for the observed 

 Items must be coded according to 

 the accompanying code tables. It is 

 important that no items be omitted. 



The basic reporting code is in the 

 following form: 



AAMddy yQLaUU L„L„L„GG 

 ddffE Sd^dwH^Hw PwPwLwLwLw 

 Xdwd„H^H„- P„PwLwLwl-w 

 The data groups Xd„.d„.H„H„ and 

 PwPwLwUl-w may be repeated as 

 many times as necessary to describe 

 all swell systems present, or omitted 

 entirely if no swell is present. 

 Groups SdwdwHwH„ PwPwLwLwLw 

 may be omitted if no wind waves 

 are present. (Note. In this case wind 

 should be reported as calm.) 

 After the items have been encoded, 

 they are written in the shipboard 

 wave observation log, any special 

 remarks are added, and the log is 

 initialed by the observer. 

 The completed log is forwarded at 

 monthly intervals to:
