gsw_specvol_anom

specific volume anomaly

Contents

USAGE:

specvol_anom = gsw_specvol_anom(SA,t,p)

DESCRIPTION:

Calculates specific volume anomaly from Absolute Salinity, in-situ
temperature and pressure, using the full TEOS-10 Gibbs function.
The reference value of Absolute Salinity is SSO and the reference value
of Conservative Temperature is equal to 0 degrees C.
TEOS-10

volume anomaly.

INPUT:

SA   =   Absolute Salinity                                      [ g/kg ]
t    =   in-situ temperature (ITS-90)                          [ deg C ]
p    =   sea pressure                                           [ dbar ]
         ( ie. absolute pressure - 10.1325 dbar )
SA & t need to have the same dimensions,
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t are MxN.

OUTPUT:

specvol_anom  =   specific volume anomaly                     [ kg/m^3 ]

EXAMPLE:

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