File UWCOMP.CSV
	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, centred around
	the hour and half hour.  The 30 minute averages are derived
from 1 minute averaged data.

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