gsw_t_deriv_chem_potential_water_t_exact

Contents

USAGE:

chem_potential_water_dt = gsw_t_deriv_chem_potential_water_t_exact(SA,t,p)

DESCRIPTION:

Calculates the temperature derivative of the chemical potential of 
water in seawater.

INPUT:

SA =  Absolute Salinity                                         [ g/kg ]
t  =  in-situ temperature (ITS-90)                             [ deg C ]
p  =  sea pressure                                              [ dbar ]
      (ie. absolute pressure - 10.1325 dbar)

SA & t need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t are MxN.

OUTPUT:

chem_potential_water_dt  =  temperature derivative of chemical potential 
                                of water in seawater           [ J/g/C ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
t =  [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
p =  [     10;      50;     125;     250;     600;    1000;]

chem_potential_water_dt = gsw_t_deriv_chem_potential_water_t_exact(SA,t,p)
