CRUISE NOTES

    INSTITUTE                 : Universitat Bremen
    COUNTRY                   : Germany
  SIGNIFICANT DATA GAPS       : Numerous short and long gaps due to
                                partial GPS availability
  SPECIAL SHIP TRACK PATTERNS :
        The cruise did WOCE WHP sections S1/A21 (Drake Passage) and S2/A12
(passage south of Africa; incomplete), with full tracer coverage.
Additional work was carried out in the northern Weddell Sea.  Taken
together this work at the same time completed the SAVE field work, and by
this the large-volume WOCE tracer work in the Atlantic sector.  An account
of the cruise (in German, including all 5 legs of cruise no. 11) has been
given to Roether et al. (1990).

  COMMENTS                    :  This cruise included WOCE One-Time Line S04 
and Repeat Line SR02.  However, the ADCP data for these legs were not 
processed and are assumed to have low quality.

IMPORTANT NOTE ABOUT THE DATA:
The profiles were integrated over the time integral between two succesive 
fixes of the ship's position available from GPS.  Thus the time between
profiles various from minutes to hours.  The depth separation is consistently
8 m.  These data have been adopted to the NODC Shipboard ADCP Standard Subset 
format.  The original files as provided by AWI are also available.  

A HIGH-RESOLUTION (CODAS) DATABASE IS NOT AVAILABLE FOR THIS SET.
