SW_Density    Density of sea water

=========================================================================
USAGE:  rho = SW_Density(T,S)
DESCRIPTION:
   Density of seawater at atmospheric pressure (0.1 MPa) using Eq. (8)
   given by [1] which best fit the data of [2] and [3]. The pure water
   density equation is a best fit to the data of [4]. 
   Values at temperature higher than the normal boiling temperature are
   calculated at the saturation pressure.

INPUT: 
   T = temperature [degree C] (ITS-90)
   S = salinity    [g/kg] (reference-composition salinity)

OUTPUT:
   rho = density   [kg/m^3]

VALIDITY: 0 < T < 180 C; 0 < S < 160 g/kg;
 
ACCURACY: 0.1
