gsw_t_maxdensity_exact

Contents

USAGE:

t_maxdensity_exact = gsw_t_maxdensity_exact(SA,p)

DESCRIPTION:

Calculates the in-situ temperature of maximum density of seawater.
This function returns thein-situ temperature at which the density
of seawater is a maximum, at given Absolute Salinity, SA, and sea 
pressure, p (in dbar). 

Click for a more detailed description of calculating the in-situ temperature of maximum density.

INPUT:

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

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

OUTPUT:

t_maxdensity_exact  =  in-situ temperature at which the density of
                       seawater is a maximum for given Absolute 
                       Salinity and pressure.                 [ deg C ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
p =  [     10;      50;     125;     250;     600;    1000;]

t_maxdensity_exact = gsw_t_maxdensity_exact(SA,p)

t_maxdensity_exact =

  -3.725008913916380
