37      !! ** Purpose :  - Time stepping of SBC including sea ice (dynamic and thermodynamic eqs.)
38      !!               - Time stepping of OPA (momentum and active tracer eqs.)
39      !!               - Time stepping of TOP (passive tracer eqs.)
40      !!
41      !! ** Method  : -1- Update forcings and data
42      !!              -2- Update vertical ocean physics
43      !!              -3- Compute the t and s trends
44      !!              -4- Update t and s
45      !!              -5- Compute the momentum trends
46      !!              -6- Update the horizontal velocity
