!!****  *MOD1D_n*  
!!
!!    PURPOSE
!!    -------
!     Source that exchanges Fluxes and SST between SURFEX (coupling_seaflux) 
!     and the oceanic 1D model in TKE eqations (mixtl_n) 
!     
!!**  METHOD
!!    ------
!     Change turbulent fluxes in solar, non solar, and fresh water fluxes 
!     with the oceanic convention for orientation of fluxes
!     The stress of wind is exchange between SURFEX and TKE model
