# gsw_rho_t_exact

**in-situ density of seawater**

## Contents

## 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)
