gsw_t_freezing

in-situ temperature freezing point

Contents

USAGE:

t_freezing = gsw_t_freezing(SA,p,saturation_fraction)

DESCRIPTION:

Calculates in-situ temperature freezing point of sea water.

in-situ temperature freezing.

INPUT:

SA  =  Absolute Salinity                                        [ g/kg ]
p   =  sea pressure                                             [ dbar ]
       ( i.e. absolute pressure - 10.1325 dbar )
       
OPTIONAL:

saturation_fraction  =  the saturation fraction of dissolved air  
                        in seawater
(i.e., saturation_fraction must be between 0 and 1, and the 
default is 1, completely saturated) 

p & saturation_fraction (if provided) may have dimensions 1x1 or Mx1
or 1xN or MxN, where SA is MxN.

OUTPUT:

t_freezing = in-situ temperature at which seawater freezes.    [ deg C ]
             (ITS-90)

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
p =  [     10;      50;     125;     250;     600;    1000;]
saturation_fraction = 1;
t_freezing = gsw_t_freezing(SA,p,saturation_fraction)
t_freezing =
