gsw_pt0_from_t_ice

Contents

USAGE:

pt0_ice = gsw_pt0_from_t_ice(t,p)

DESCRIPTION:

Calculates potential temperature of ice with reference pressure,
pr = 0 dbar.  The present routine is computationally faster than the
more general function "gsw_pt_from_t_ice(t,p,pr)" which can be used 
for any reference pressure value.

INPUT:

t   =   in-situ temperature (ITS-90)                          [ deg C ]
p   =   sea pressure                                           [ dbar ]
        (ie. absolute pressure - 10.1325 dbar)

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

OUTPUT:

pt0_ice  =  potential temperature of ice                      [ deg C ]
            with reference sea pressure (pr) = 0 dbar.
Note. The reference sea pressure of the output, pt0_ice, is zero dbar.

EXAMPLE:

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

pt0_ice = gsw_pt0_from_t_ice(t,p)

pt0_ice =

  -10.787787898205298
  -13.443730926050607
  -12.837427056999708
  -12.314321615760905
  -11.017040858094250
