Instructions: METADATA FORM FOR SHIPBOARD ADCP 

     Three forms are given to the data producer: a blank 
form, an example, and this instruction file.  Please
fill in the blank form.  If you encounter an uncertain
entry, please refer to the example and instruction files.
If an item is still uncertain or if the information is
not available, leave the entry blank.  It would be of
greatest assistance to us if you could fill out the
readily available entries and return the form at your
earliest convenience, rather than getting bogged down
on a few uncertain items.

     Please also review the items in the file prc_chk.lis
which is a check list of editing steps and configuration
options that the user may have applied to the data set.  
This information is used for creating a data processing 
mask for automatic documentation of how the data were processed.

     Once completed, please return the metadata form via email,
a diskette (IBM-PC compatible preferred), or handwritten to 

     Mr. Patrick Caldwell

     Below, please find a repeat of the meta data form and 
notes on various keyword entries that require additional explanation.  
For the entries below, the first group are primary keywords and are 
prefixed with the pound sign (#).  These should be given priority.  
These keywords are used with the inventory and data retrieval system 
and are necessary components of the archive system.  The keywords under 
#GENERAL_INFORMATION: are secondary keywords.  For these, please 
provide as much readily available information as possible.  If an 
entry is uncertain, please leave it blank.

 #DATA_DATES: yyyy/mm/dd hh/mm/ss to yyyy/mm/dd hh/mm/ss
  #LAT_RANGE: [+/-]  dd mm.tt  to [+/-]  dd mm.tt 
  #LON_RANGE: [+/-] ddd mm.tt  to [+/-] ddd mm.tt 
#DEPTH_RANGE: dd to dddd m

       the above can be completed automatically at a later 
       date when the data are loaded into the CODAS database     

#PLATFORM_NAME: <free form, ship name>
#PRINCIPAL_INVESTIGATOR_NAME: <free form, multiple ok> 

        refers to the one(s) responsible for the data.

#PI_INSTITUTION: <free form, multiple ok>   
#PI_COUNTRY: <free form, multiple ok>   
#PROJECT: <free form, may be joint>
#CRUISE_NAME: <free form>     
      #PORTS: <free form>
#GEOGRAPHIC_REGION: <free form>
#PROCESSED_BY: <free form, institution>
 #NAVIGATION: <free form, type such as GPS or transit>
#QUALITY_NAV: <excellent> <good> <fair> <poor> <none>
   This is for a quick glance at the caliber of the data set;
   it is not easy to generalize but since the categories are 
   so broad, most will be described as <good> while only 
   exceptionally good data sets will be <excellent> and 
   exceptionally bad data sets given <poor>.  Lastly if
   not available, <none>.  This information would define the 
   application for the ADCP data as shear only (poor or no 
   navigation) or absolute currents (fair, good, or excellent 
   navigation).
#GENERAL_INFORMATION: <free form> 
   This is all other pertinent information regarding 
   instrumentation, processing, calibration, etc.  Please do 
   not let the length of this form hinder your efforts to 
   provide metadata; please provide the information at hand 
   and leave the unknown entries blank.
