gsw_t_from_pt0_ice

Contents

USAGE:

t_ice = gsw_t_from_pt0_ice(pt0_ice,p)

DESCRIPTION:

Calculates in-situ temperature from potential temperature with a 
reference pressure of 0 dbar of ice.

It is also possible to calculate in-situ temperature from potential
temparature using the function gsw_pt_from_t_ice.  In this case it 
would be called with potential temperature referenced to 0 dbar, 
pt0, and the in-situ pressure (i.e. gsw_pt_from_t_ice(pt0_ice,0,p)). 

INPUT:

pt0_ice =  potential temperature of ice                           [ deg C ]
           with reference sea pressure (pr) = 0 dbar.
Note. The reference sea pressure of the input, pt0_ice, is zero dbar.
p      =   sea pressure                                            [ dbar ]
         ( i.e. absolute pressure - 10.1325 dbar )

p may have dimensions 1x1 or Mx1 or 1xN or MxN, where pt0_ice is MxN.

OUTPUT:

t_ice   =  in-situ temperature of ice (ITS-90)                    [ deg C ]

EXAMPLE:

pt0_ice = [-10.7856; -13.4329; -12.8103; -12.2600;  -10.8863;  -8.4036;]
p = [     10;      50;     125;     250;     600;    1000;]

t_ice = gsw_t_from_pt0_ice(pt0_ice,p)

t_ice =

  -10.783412084414074
  -13.422068638139141
  -12.783170223330448
  -12.205667526492039
  -10.755496924674144
