BATHYTHERMOGRAPH    RECORDS AND  REPORTS LEARNING   OBJECTIVE:  Identify   what records are required to be forwarded to record collection centers. All   successful   bathythermograph   observations should be encoded and transmitted, regardless of clas- sification.  Bathythermograph  observations  are  trans- mitted  to  one  of  two  Collective  Address  Designators (CADS)—OCEANO   WEST   or   OCEANO   EAST,  as specified  in  NAVMETOCCOMINST  3140.1,  United States  Navy  Meteorological  and  Oceanographic Support  System  Manual.  All  transmitted  observations to either of the CADs are automatically entered in both the  current  information  and  the  historical  information data bases. The information then becomes available for acoustic data predictions for all fleet units through the Fleet   Numerical   Meteorology   and   Oceanography Center’s  data  networks. The only records required to be saved indefinitely are  the  originals  of  the  completed  CNMOC  3167/2 bathythermograph  log  sheets.  Each  observation  must be  properly  identified  by  completing  the  data  block preprinted on each section of the chart. As directed by NAVMETOCCOMINST 3140.1, unclassified original bathythermograph   log   sheets   are   forwarded   to   the National Oceanographic Data Center, NOAA/NESDIS E/OC12,  13  15  E  West  Highway,  Silver  Spring, Maryland, 20910-3282, by the fifth day of the following month. Original classified log sheets are forwarded to the   Naval   Oceanographic   Office,   1002   Balch Boulevard,  (ATTN  Code  N34D),  Stennis  Space  Center, Mississippi  39522-5001,  by  the  fifth  day  of  the following month. A meteorological records transmittal form should accompany the log sheets in lieu of a cover letter. NEVER delete geographical positions to make any observation unclassified, as observations without position  data  are  useless.  Instructions  for  the  proper packaging  and  handling  of  classified  log  sheets  are discussed in OPNAVINST 5510.1, Department of the Navy  Information  and  Personnel  Security  Program Regulation. SECNAVINST  5212.5,  Navy  and  Marine  Corps Records  Disposition  Manual,  provides  guidance  for  the retention   of   temporary   records.   Temporary bathythermograph  records,  such  as  the  used  recorder charts  removed  from  the  “take-up”  roll  and  any duplicate copies of the log sheets, are retained on board until no longer needed (usually no more than 6 months). Q28. Q29. Q30. REVIEW  QUESTIONS What   manual   outlines   procedures   for   the transmission of bathythermograph observation data? Where  are  classified  original  bathythermograph log  sheets  mailed? How long are duplicate copies of bathythermo- graph log sheets normally retained on board?
