Data Format:
   ASCII text files formatted in accordance with NODC F015
   ASCII Header information
   1-db averaged data listed in columns

Instrument Type:
   Sea-Bird 911 Plus CTD

Instrument Calibration:
   NWRCC calibration prior to spring field season
   Salinity samples taken during cruise allowed precision of
   salinity measurements to <.0015 psu.

Data Processing/Reduction Methodology
   Standard recommended Sea-Bird processing for this instrument
   was employed.
   Data was averaged to 1 - m bins.
   The resulting data was despiked to limit density inversions 
   to <0.02 sigma-t units (i.e. 10E-05 kg m-3)

Data were made available to Sid Stillwaugh at NODC
via direct electronic data transfer on 15 Jul.-1999
