    The CTD stations are as follows:
    
    1         TEST
    2-82      TOTTEN/DALTON REGION
    83-133    MERTZ REGION
    134-141   SR3
    
    
    
    
    CTD DATA
    --------
    * SeaBird CTD 704 was used for the entire cruise.
    
    * CTD data are in text files named *.all, containing 2-dbar data.
    An example of file naming convention:
    
    a14024010.all -  a = Aurora Australis
                    14 = year of first CTD
                    02 = cruise number (i.e. voyage 2 in this case)
                     4 = CTD instrument number
                   010 = CTD cast number
    
    * Post-processed bathymetry data for the cruise are included in the
    file headers and station data file. All bottom depths are corrected
    for the local sound speed at each station.
    
    * The CTD 2 dbar files consist of a 15 line header with station info,
    followed by the data in column format, as follows:
    
    column 1 - pressure (dbar) 
    column 2 - temperature (degrees C, T90 scale) 
    column 3 - conductivity (mS/cm) 
    column 4 - salinity (PSS78) 
    column 5 - dissolved oxygen (umol/l) 
    column 6 - fluorescence (manufacturer supplied calibration giving
               units ug/l)
    column 7 - photosynthetically active radiation (PAR) (manufacturer supplied
               calibration giving units uEinsteins/m2.sec)
    column 8 - transmittance (% transmittance, referenced to clean water value)
    column 9 - number of data points used in the 2 dbar bin
    column 10 - fluorescence, upcast data
    column 11 - PAR, upcast data
    column 12 - transmittance, upcast data
    column 13 - number of data points used in the 2 dbar bin, upcast data
    
    
    * CTD data are all 2 dbar averaged values, for each even valued pressure bin.
    
    * columns 2 to 9 are downcast data; columns 10 to 13 are upcast data
    (both downcast and upcast data are supplied for fluorescence, PAR and transmittance).
    
    * All files start at 2 dbar, and there is a line for each 2 dbar bin.
    Any missing data are filled by the null value -9.0
    
    * Temperature/conductivity/salinity data are from the primary temperature
    and conductivity sensor pair for all CTD casts.
    
    * Station information contained in the headers is described below in the
    section on station data, with the addition of:
     lastbin = deepest 2 dbar pressure bin (dbar) for the cast
     pressure (dbar) at the minimum altimeter value
     local sound speed (m/s) used for correction of bottom depths
    
    * Note that all oxygen values are volumetric (i.e. umol/l).
    
    * Note that deeper fluorescence data are slightly negative in value,
    due to the calibration coefficients supplied.
    
    * Note that maximum transmittance values are slightly less than the
    expected 100%, due to a small calibration error.
    
    
    
    
    BOTTLE DATA
    -----------
    * All bottle oxygen data are finalised
    
    * Note that all nutrient and oxygen values are volumetric (i.e. umol/l).
    
    * The bottle data (hydrochemistry) are contained in the a1402.bot text file, with the
    following columns:
    
    column 1 - cast number
    column 2 - ctd pressure (dbar)
    column 3 - ctd temperature (deg. C, T90 scale)
    column 4 - null data (i.e. -9.0)
    column 5 - ctd conductivity (mS/cm)
    column 6 - ctd salinity (PSS78)
    column 7 - bottle salinity (PSS78)
    column 8 - phosphate (umol/l) 
    column 9 - nitrate (umol/l) (i.e. total nitrate+nitrite)
    column 10 - silicate (umol/l)
    column 11 - bottle dissolved oxygen (umol/l)
    column 12 - bottle flag (1=good,0=suspicious,-1=bad, relevant to
                salinity values for CTD calibration i.e. not applicable to other bottle data)
    column 13 - niskin bottle number
    column 14 - ctd fluorescence (units as per CTD note above)
    column 15 - ctd photosynthetically active radiation (PAR) (units as per CTD note above)
    column 16 - ctd transmittance (units as per CTD note above)
    
    
    * Columns 2, 3, 5, 6, 14, 15 and 16 are all the averages of CTD upcast burst data 
    (i.e. averages of the 10 seconds of CTD data from 5 seconds prior to 5 seconds after each bottle firing). 
    Temperature, conductivity and salinity data are from the primary sensor pair.
    
    * Any missing data are filled by the null value -9.0
    
    
    
    
    STATION INFORMATION
    -------------------
    A summary of the station information is contained in the a1402.sta file
    (this station information is also included in the matlab file a1402.mat).
    All times are UTC. The data columns for each cast are:
    
    CTD cast number

    * Decimal times are decimal days from 2400 on 31st Dec. 2013 (so, for example,
    midday on 2nd January 2015 = decimal time 366.5).
    
    * Any missing values are filled by a blank
    
    
    
    
    MATLAB FORMAT
    -------------
    
    * In the matlab files, column number for each array corresponds with CTD cast number.
    
    * In the matlab files, NaN is a null value.
    
    * In the matlab CTD file, profiles are padded down to 4400 dbar.
    
    * In the matlab bottle file, the rows 1 to 24 are the shallowest to deepest Niskins respectively.
    
    * CTD data are in matlab format in the file a1402.mat, which includes station info.
    The array names have the following meaning:

    date is ddmmyyyy date
    altimeter = minimum altimeter value (m)
    press_alt = pressure (dbar) at the minimum altimeter value
    
    
    * Bottle data are also in matlab format in the file called a1402bot.mat,
    which includes some of the station info.
    The array names have the following meaning:
    "ctdbot" refers to upcast CTD burst data, for the parameters:

    * For Antarctic shelf data (stn 1-133), when lowering or raising of the CTD slowed down
    in regions of significant vertical structure, high variability was at times evident in the profile data.
    Examples of this are sensor spikes near the bottom of stations 50, 55 and 72.
    This variability was also evident as sensor drift during bottle stops. In all these cases
    any unusual features can be seen in both the primary and secondary sensor data, however
    the primary and secondary sensor data mismatch is more than usual. Possible reasons are:
    - highly variable ocean structure (more likely)
    - sensor time constants (possible contributor)
    - interference from ice crystals forming as the CTD slows (speculative)
    These data are not flagged as suspect, but are perhaps at the limit what the CTD can accurately 
    measure in a highly variable environment.
    
    * Many shelf stations were taken around highly variable bottom topography, and in a few cases
    (e.g. stations 3 and 114) a mismatch occurred between bottom depth from the 12 kHz sounder and
    bottom depth as measured by the CTD (i.e. pressure at bottom of cast + altimeter reading).
    Clearly the CTD does not always lie in the measurement cone of the sounder; and bottom picking
    of sounder data (during the quality control) can be difficult in highly variable topography.
    
    * 2 dbar upcast fluorescence and transmittance data do not always match the fluorescence and
    transmittance upcast 10 sec burst data - due to the difference between 2 dbar and
    10 second averageing on what is often highly featured data.
    
    * A full data report is in the file a1402.pdf.
