# gsw_specvol_CT_exact

`specific volume`

## USAGE:

`specvol_CT_exact = gsw_specvol_CT_exact(SA,CT,p)`

## DESCRIPTION:

```Calculates specific volume from Absolute Salinity, Conservative
Temperature and pressure.```
```Note that this function uses the full Gibbs function.  There is an
alternative to calling this function, namely gsw_specvol(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 and CT are MxN.```

## OUTPUT:

`specvol_CT_exact  =  specific volume                               [ 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_CT_exact = gsw_specvol_CT_exact(SA,CT,p)`
`specvol_CT_exact =`
` 1.0e-003 *`
