# gsw_rho_t_exact

`in-situ density of seawater`

## USAGE:

`rho_t_exact = gsw_rho_t_exact(SA,t,p)`

## DESCRIPTION:

```Calculates in-situ density of seawater from Absolute Salinity and
in-situ temperature.  Note that the output, rho_t_exact, is density,
not density anomaly; that is, 1000 kg/m^3 is not subracted from it.```

## INPUT:

```SA  =  Absolute Salinity                                        [ g/kg ]
t   =  in-situ temperature (ITS-90)                            [ deg C ]
p   =  sea pressure                                             [ dbar ]
( i.e. 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:

`rho_t_exact  =  in-situ density (not density 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;]```
`rho_t_exact = gsw_rho_t_exact(SA,t,p)`
`rho_t_exact =`
`1.0e+003 *`
