818. Supervision and Inspection 



Although the officer-in-charge is responsible for the records, he is usually fully 

 engaged otherwise during the actual sounding, and his assistant, usually the right angle- 

 man, shall supervise the actual recording and check closely the marner and accuracy 

 with which the recorder does his work. It is the latter who usually tells the recorder 

 what miscellaneous entries to make. He should see that clear explanatory notes are 

 entered wherever necessary. Some hydrographic or topographic information is found 

 only in the "Remarks" column. Such notes are often of supreme importance, as for 

 example, those referring to rocks awash and revision of shoreline. He should make 

 certain that they are adequate and accurate. Question marks should not be left in 

 the Record to cause future confusion. Rejections of shoal soundings, which may be 

 obvious to the hydrographer, should be logicall}^ and fully explained. (See 3413.) 



A daily review of the boat sheet and Sounding Record shall be made by the hydrog- 

 rapher at which time any errors or omissions in the recorded data shoidd l)e rectified 

 (see 3246). 



The hydrographer in charg(> of the party, or of the watch if on board ship, shall be 

 responsible for the accm-acy and adequacy of the recorded data and at the end of the 

 day's work or watch shall approv^e the record for that day, or watch, over his signatiu'e 

 (see 3412). The signature shall be entered in the appropriate space in Stamp No. 36 

 (fig. 181) which should l)e impressed at the end of each day, or each watch if operations 

 are on a Avatoh basis. 



Sounding Records shall be examined occasionally by the Chief of Party to make 

 sur(> that they are being kept in accordance with the I'equirements and are complete and 

 satisfactory in all respects. The examination required is only a general one, the hydrog- 

 rapher in immediate charge being specifically responsible for the day-to-day examina- 

 tion and for the approval of each day's recorded data. The Chief of Party need not 

 sign the Sounding Records. The space provided in Stamp No. 36 may be disregarded. 

 If the Chief of Party does inspect the Records generally, he may place his signature in 

 this space, with inclusive dates to indicate that part of the Records to w^hich his inspec- 

 tion applies. 



General instructions to the hydrographer by the Chief of Party should be WTitten 

 in the Sounding Record and signed by him. (See also 3411.) 



819. Completion of Sounding Records 



After the completion of a hydrographic survey, all of the Sounding Records for that 

 sui'vey shall be gathered together and the following completion steps accomplished: 



a. Numbering. — The Records are to be grouped in the proper order, the various groups shall be 

 combined, and the complete set of Records shall be numbered consecutively and permanently, includ- 

 ing any volumes used solely for cuts or other miscellaneous data. 



The field number and registry number of the hydrographic survey shall be plainly marked in 

 pencil on the cover label and the title page of each volume of soundings. In the relatively rare case 

 where parts of a Sounding Record have to be plotted on different smooth sheets, the numbers of both 

 surveys shall be entered on the cover label and reference must be made on the proper pages of the Rec- 

 ord to the sheets involved. It is not necessary to copy a portion of the Record into another volume. 

 (See 3213.) 



b. Cover label. — The data called for on the cover label and title page shaU be entered in black 

 drawing ink, except the position numbers and day letters, which shall be entered with ink of the color 

 or colors used in the Record, and the survey numbers which are left in pencil. 



c. Deviation tabic. — The deviation table for the compass used for hydrograph}' shall be entered on 

 page 1 of the first volume of each set of Records, and in the proper Record (with reference to date) if
