•  Since  1993,  and  as  a  result  of  German  unification,  an  additional  and  significant  contribution
of  real-time  temperature  data  has  come  from  the  German  Navy  (Fig.  23).  However,  this  realtime ­
  data  source  dried  up  completely  in  2002  due  to  the  Navy’s  decision  to  declassify  their
data  not  earlier  than  1  month  after  collection.  This  decision  was  made  for  safety  reasons.
Therefore,  and  to  avoid  data  losses,  the  non-real-time  BATHY  messages  are  submitted  to
MEDS  (Canada)  for  archiving.
•  The  SST  programme  of  BSH,  which  was  established  in  1987,  has  been  supplemented  by
SSS  measurements  since  1996.  Data  are  collected  by  both  governmental  and  commercial
vessels  using  Pt100  hull  contact  thermometers  (Sy  and  Ulrich,  1990)  or  SBE-21
thermosalinographs.  All  SST  and  SSS  data  received  at  BSH  in  time  are  inserted  onto  GTS
as  TRACKOB  coded  reports.  This  programme  is  restricted  to  the  North  and  Baltic  Seas  with
special  focus  on  the  German  EEZ  (Fig.  24)  and  does  not  follow  the  TWI  line  system.
