gsw_chem_potential_water_t_exact
chemical potential of water in seawater
Contents
USAGE:
chem_potential_water_t_exact = gsw_chem_potential_water_t_exact(SA,t,p)
DESCRIPTION:
Calculates 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_t_exact = chemical potential of water in seawater
[ J/g ]
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_t_exact = gsw_chem_potential_water_t_exact(SA,t,p)
