gsw_rho_alpha_beta_CT_exact

in-situ density, thermal expansion & saline 
contraction coefficients from CT

Contents

USAGE:

[rho, alpha_CT, beta_CT] = gsw_rho_alpha_beta_CT_exact(SA,CT,p)

DESCRIPTION:

Calculates in-situ density, the appropiate thermal expansion coefficient
and the appropriate saline contraction coefficient of seawater from
Absolute Salinity and Conservative Temperature.
Note that this function uses the full Gibbs function.  There is an
alternative to calling this function, namely gsw_rho_alpha_beta(SA,CT,p), 
which uses the computationally-efficient 48-term expression for density 
in terms of SA, CT and p (McDougall et al., 2011).

INPUT:

SA  =  Absolute Salinity                                        [ g/kg ]
CT  =  Conservative Temperature                                [ deg C ]
p   =  sea pressure                                             [ dbar ]
       ( i.e. absolute pressure - 10.1325 dbar )
SA & CT need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & CT are MxN.

OUTPUT:

rho       =  in-situ density                                  [ kg/m^3 ]
alpha_CT  =  thermal expansion coefficient                       [ 1/K ]
             with respect to Conservative Temperature
beta_CT   =  saline contraction coefficient                     [ kg/g ]
             at constant Conservative Temperature

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
CT = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]
p =  [     10;      50;     125;     250;     600;    1000;]
