gsw_thermobaric

thermobaric coefficient (48-term equation)

Contents

USAGE:

thermobaric = gsw_thermobaric(SA,CT,p)

DESCRIPTION:

Calculates the thermobaric coefficient of seawater with respect to
Conservative Temperature. This routine calculates rho from the
computationally-efficient 48-term expression for density in terms of
SA, CT and p (McDougall et al., 2011).

coefficient.

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:

thermobaric  =  thermobaric coefficient with respect
                to Conservative Temperature.               [ 1/(K Pa) ]
Note. The pressure derivative is taken with respect to
  pressure in Pa not dbar.

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;]
thermobaric = gsw_thermobaric(SA,CT,p)
