   NOTE:

   The CTD data for casts 007 - 028 were affected to varying degrees by
   a cracked conductivity sensor.  By comparing the measured CTD
   conductivity values with the calculated conductivity values for the
   bottle salinities at in situ temperatures and pressure, it appeared
   that for most casts the CTD salinity values could be corrected by
   applying a linear regression fit to the CTD conductivities to make
   them equal to the bottle conductivity values.  Because casts 14 and
   22 did not have corresponding bottle salts and casts 15, 19, 20 and
   24 still looked odd after the regression, these casts were not
   adjusted and the salinities deleted.  In some cases, salinities were
   deleted from selected sections of the casts.  For CTD casts 7 - 28,
   CTD salinities and related computed values should be used with caution.
