gsw_specvol_anom

specific volume anomaly (48-term equation)

Contents

USAGE:

specvol_anom = gsw_specvol_anom(SA,CT,p)

DESCRIPTION:

Calculates specific volume anomaly from Absolute Salinity, Conservative
Temperature and pressure.  It uses the computationally-efficient 48-term
expression for density as a function of SA, CT and p (IOC et al., 2010).
The reference value of Absolute Salinity is SSO and the reference value 
of Conservative Temperature is equal to 0 degress C.

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  =  specific volume anomaly                      [ m^3/kg ]

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 = gsw_specvol_anom(SA,CT,p)
