gsw_rho_CT_exact

in-situ density

Contents

USAGE:

rho_CT_exact = gsw_rho_CT_exact(SA,CT,p)

DESCRIPTION:

Calculates in-situ density from Absolute Salinity and Conservative
Temperature.
Note that potential density with respect to reference pressure, p_ref, is
obtained by calling this function with the pressure argument being p_ref
(i.e. "gsw_rho_CT_exact(SA,CT,p_ref)").
Note that this function uses the full Gibbs function.  There is an 
alternative to calling this function, namely gsw_rho(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_CT_exact   =  in-situ density                             [ kg/m^3 ]

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;]
rho_CT_exact = gsw_rho_CT_exact(SA,CT,p)
