% USAGE:
%  SSO = gsw_SSO
%
% DESCRIPTION:
%  SSO is the Standard Ocean Reference Salinity (35.16504 g/kg).
%
%  SSO is the best estimate of the Absolute Salinity of Standard Seawater
%  when the seawater sample has a Practical Salinity, SP, of 35
%  (Millero et al., 2008), and this number is a fundmental part of the 
%  TEOS-10 definition of seawater.  
% 
% OUTPUT:
%  SSO  =  Standard Ocean Reference Salinity.                      [ g/kg ]
