Data Set Description:

     This file contains the explanation of the data in the Southern Surveyor
underway data set taken during cruise SS 11/95, part of the ACE-1 experiment.
Each column heading is explained, and any caveats for these preliminary data
sets are noted.

     All data are presented as 30-minute averages, centered around the hour and
half hour.  The 30-minute averages are derived from 1-minute averaged data.

Format: comma-delimited ASCII with fields:

Column 1:  Date (YYYY/MM/DD) (UTC)
Column 2:  Time (HH:MM:SS) (UTC)
Column 3:  Julian decimal day, with time in half-hour increments.  (UTC)
Column 4:  Decimal Latitude:  4253.83 is 42 degrees 53.83 minutes
Column 5:  This is South
Column 6:  Decimal Longitude:  14721.01 is 147 degrees 53.01 minutes
Column 7:  E:  All longitudes are East.
Column 8:  GPS_Speed: This is the doppler log record of ships speed and
           represents an accurate vessel speed through the water.
Column 9:  GPS_Heading: Ships heading from the gyro compass.
Column 10:  EK500_depth:  depth of water under the ships keel.  Zero values mean
           the echo sounder has lost bottom lock, and should be ignored.
Column 11:  DT_Air_Temp:  Air temperature in degrees celsius
Column 12: DT_Wind_Speed_Knots:  wind speed in knots
Column 13: True wind direction:
Column 14: DT_Light: masthead photosynthetically active radiation (PAR).
Column 15: Thermosalinograph salinity:  NB THIS IS UNCORRECTED DATA
Column 16: Thermosalinograph salinity:  NB THIS HAS BEEN CORRECTED USING THE
           CTD SURFACE SALINITY DATA.  IT IS THE DATA TO USE.
Column 17: Thermosalinograph temperature
Column 18: Fluoresence measured in the thermosalinograph outflow water.
Column 19: Data from column 17 corrected to chlorophyll a using a regression
           of fluoresence to chla from discrete samples.
