#platform_name:                    Wecoma
#collection_methods:  
 (i.e. how were the data obtained) 

 SeaBird 9/11 plus CTD in General Oceanics rosette, with 2 
 salinity samples per cast (usually); salinity samples analyzed 
 onshore with a Guildline Autosal; data acquired with SBE Seasave 
 Win32 v1.10, using MRK files to match CTD and sample data.

#analysis_methods:
 (i.e. how were the data processed, calibrated etc)

  - in situ conductivity calibration determined from comparison 
    of CTD values from *.mrk files with sample conductivity
    (calculated from samples salinity and CTD temperature); 

  - correction (if present) incorporated after final Seasoft step;
    data processed using Seasoft modules DATCNV, ALIGNCTD, CELLTM  
    (with alpha = 0.03 and 1/beta = 7 sec), LOOPEDIT (with minimum 
    velocity = 0.1), and BINAVG (averaging to 1 dbar values).

  - the 1-dbar average T,C data were transferred to Sun 
    workstation where we used standard algorithms (Fofonoff and 
    Millard, 1983) to calculate salinity, potential temperature, 
    density anomaly (sigma-theta), specific volume anonomaly, and 
    geopotential anomaly.

     temperature sensor SN 1371 (calibrated at SBE 08 February 2001),
     conductivity sensor SN 1021 (calibrated at SBE 10 April 2001). 
     conductivity sensor SN 1030 (calibrated at SBE 10 April 2001).

#format_description:
 (e.g. description of the header, data, record layouts. Include
 units, scales, resolution, accuracy)

  Files contain 13 lines of header with a format of variable
   length character strings: ('h ',a), followed by the data
   with a format of 
     (f7.1,4f8.3,f7.1,f8.3,f7.3,f6.1,f7.3,f8.3,2f8.2,f7.3). 
   The header contains: 
      file name, latitude, longitude, time, bottom depth,
      station number, station name (may be blank),
      2 comment lines, and the data column labels. 
   The data includes:
      pressure (dbars), accurate to better than plus/minus 1 db
      temperature (C), accurate to plus/minus 0.01 C
      salinity (psu), accurate to plus/minus 0.004 psu
      potential temperature (C), 
      Sigma-theta (kg/cubic meter),
      specific volume anomaly (cl/ton),
      geopotential anomaly (J/kg)
      fluorescence (0-5 v),
      light transmission (0-100 %) 
      par (0-5 v),
      oxygen current (0-5 v)
      oxygen temperature (C)
      oxygen saturation (ml/l)
      fluoroscein (0-5 v)
      
    The last data column (fluorescein) is only present in casts 22-33.

 Most files are identified as "w0108ac.##"  where ## is the cast number. 
 Two stations were repeated immediately; these are identified in the files
 by appending a "b" (.##b).  A flourometer tuned to detect fluoroscein
 was added for work on August 13 and 14 (casts 22-33).  To indicate the
 presence of additional column of data, they are identifed as "w0108ac2.##".  
 Some casts were not submitted (casts 28,31,33) since these were lesser
 quality towyo series aimed at detecting a fluoroscein dye injection.

#submittor_documentation:          *
 any textual information about the data, provided by the submitter,
 or investigator, (not NODC folks)  For example, in most cases this
 has been an ASCII text file accompanying the data on a DAT , diskette,
 or CDROM.  It may contain information which is redundant with other
 parts of this form.
