8435 HYDROGRAPHIC MANUAL PaGE 792 



the same corrections are applicable to several surveys, a copy of the data shall be 

 included in each Descriptive Report. 



8435. Buoy Station Locations 



Where buoy stations or R.A.R. stations were used and final positions of these have 

 been derived other than by plotting on the smooth sheet, an alphabetic list shall 

 be prepared giving the correct latitude and longitude of each station. If two or more 

 buoy stations in close proximity to each other were used, the inclusive dates between 

 which each was used shall be noted. 



A concise reference to the method of location, the records containing the observed 

 data and the computations, and to the special report which contains the buoy location 

 data, if one was submitted, shall be added. (See 832.) No other data should be in- 

 cluded on this separate insert. 



8436. Miscellaneous 



After the abstract of buoy locations and before the approval sheet there shall be 

 inserted any other data which are believed to be an essential part of the records. If these 

 are voluminous they should be bound separately in their proper groups (see section 83) 

 and forwarded with the records of the survey, but should not be included m the Descrip- 

 tive Report, Examples of such are the original observations, computations, and plotted 

 lines of positions of astronomic sights; the computations of buoy stations; the velocity 

 of sound tests; and the computations of taut- wire traverses. Smooth copies of these 

 are not required^ — the originals will suffice — nor is it necessary to ink the originals 

 (see for example 3382). 



8437. Approval Sheet 



The Chief of Party shall furnish on a separate sheet of paper, attached to the 

 Descriptive Report, a signed statement of approval of the survey. This shall serve as 

 a general approval of the smooth sheet and all accompanying records (see 3411 and 

 7941). It should include a statement as to the amount of personal supervision of the 

 field work and the frequency with which he examined the boat sheet, whether the sur- 

 vey is complete and adequate, whether additional field work is recommended, and any 

 additional information not included in the Descriptive Report that may be of assistance 

 to the Office in reviewing the survey. 



When a hydrographic sheet is transferred elsewhere for completion, in accordance 

 with instructions from the Office, approval shall be made of only that part of the smooth 

 plottmg completed at the time of transfer. If the completed smooth sheet is returned 

 to the Chief of Party for examination prior to transmittal to the Washington Office, 

 his approval of the entire sheet should then be added. 



844. Additions at Washington Office 



Between the receipt of the hydrographic sheet and accompanying records at the 

 Washington Office and the final approval of the survey by the administrative officers, 

 certain forms and reports are added to the Descriptive Report, in the order referred to 

 below. The purpose of each addition is briefly stated, 



a. Records accompanying survey and Office statistics. — On this form an entry is made of the 

 records accompanying the survey, such as, the number of boat sheets, sounding volumes, and wire- 

 drag volumes, but this is in no sense a list of the data required in 842Z.
