%
%%% Syntax
%
%   v = visc35( T )
%
% * [T] temperature in units of degrees Celsius. 
% * []
% * [v] viscosity in units of metres-squared per second. 
%
%%% Description
%
% Return an approximation of the kinematic viscosity, $\nu$, in units of
% $\si{\square\m\per\s}$, based on temperature, in units of
% $\si{\celsius}$. The kinematic viscosity is derived from a
% $3^{\mathrm{rd}}$-order polynomial fit of $\nu$ against $T$ for
% salinity 35. The error of the approximation is less than
% $\SI{1}{\percent}$ for $0\le T \le \SI{20}{\celsius}$ and  $30\le S \le
% \SI{40}{PSU}$ at atmospheric pressure.
