gsw_beta_CT_exact

saline contraction coefficient at constant 
Conservative Temperature.

Contents

USAGE:

beta_CT_exact = gsw_beta_CT_exact(SA,CT,p)

DESCRIPTION:

Calculates the saline (i.e. haline) contraction coefficient of seawater
at constant Conservative Temperature.
Note that this function uses the full Gibbs function.  There is an 
alternative to calling this function, namely gsw_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).

Temperature.

INPUT:

SA  =  Absolute Salinity                                          [ g/kg ]
CT  =  Conservative Temperature (ITS-90)                         [ 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:

beta_CT_exact  =  saline contraction coefficient                  [ kg/g ]
                  at constant Conservative Temperature

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
CT = [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
p =  [     10;      50;     125;     250;     600;    1000;]
beta_CT_exact = gsw_beta_CT_exact(SA,CT,p)
