USAGE:
specvol_anom_CT_exact = gsw_specvol_anom_standard_CT_exact(SA,CT,p)
DESCRIPTION:
Calculates the standard specific volume anomaly from Absolute Salinity,
Conservative Temperature and pressure. The reference value of
Absolute Salinity is SSO and the reference value of Conservative
Temperature is equal to 0 degrees C.
Note that this function uses the full Gibbs function. There is an
alternative to calling this function, namely
gsw_specvol_anom_standard(SA,CT,p), which uses the computationally
efficient 75-term expression for specific volume in terms of SA, CT
and p (Roquet et al., 2015).
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:
specvol_anom_CT_exact = specific volume anomaly [ 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;]
specvol_anom_CT_exact = gsw_specvol_anom_standard_CT_exact(SA,CT,p)
