    530530  If the under ice shelf seas are opened (\np{ln_isfcav}{ln\_isfcav}), the depth of the ice shelf/ocean interface has to be include in  
    531531  the \ifile{isfdraft\_meter} file (Netcdf format). This file need to include the \ifile{isf\_draft} variable.  
    532   A positive value will me an ice shelf/ocean or ice shelf bedrock interface below the reference 0m ssh.  
    533   The exact shape of the ice shelf cavity (grounding line position and minimum thickness of the water column under an ice shelf, ...) can be specify in \nam{lst:namzgr_isf}.

    542    The options available to define the shape of the under ice shelf cavities are listed in \nam{namzgr_isf}{namzgr\_isf} (\texttt{DOMAINcfg} only, \autoref{lst:namzgr_isf}).

    544544   \subsection{Model ice shelf draft definition} 
     
    556556   This step is needed to take into account possible small mismatch between ice shelf draft value and bathymetry value (sources are coming from different grid, different data processes, rounding error, ...). 
    557557 
    558    \item{\np{rn_isfhw_min}{rn\_isfhw\_min}:} This parameter is minimum water column thickness in the cavity.  
     558   \item{\np{rn_isfhw_min}{rn\_isfhw\_min}:} This parameter is the minimum water column thickness in the cavity.  
    559559   Where the water column thickness is lower than \np{rn_isfhw_min}{rn\_isfhw\_min}, the ice shelf draft is adjusted to match this criterion.  
    560560   If for any reason, this adjustement break the minimum ice shelf draft allowed (\np{rn_isfdep_min}{rn\_isfdep\_min}), the cell is masked.

    579    In case of steep slope and shallow water column, it likely that 2 cells are disconnected (bathymetry above its neigbourg ice shelf draft).  
     579   In case of steep slope and shallow water column, it likely that 2 cells are disconnected (bathymetry above its neigbourging ice shelf draft).  
    580580   The option \np{ln_isfconnect}{ln\_isfconnect} allow the tool to force the connection between these 2 cells. 
    581581   Some limiters in meter or levels on the digging allowed by the tool are available (respectively, \np{rn_zisfmax}{rn\_zisfmax} or \np{rn_kisfmax}{rn\_kisfmax}).

    12181218     \np{ln_isfcav_mlt}{ln\_isfcav\_mlt}\forcode{ = .true.} activates the ocean/ice shelf thermodynamics interactions at the ice shelf/ocean interface.  
    12191219     If \np{ln_isfcav_mlt}\forcode{ = .false.}, thermodynamics interactions are desctivated but the ocean dynamics inside the cavity is still active. 
    1220      The logical flag \np{ln_isfcav}{ln\_isfcav} control wether or not the ice shelf cavities are closed. \np{ln_isfcav}{ln\_isfcav} is not defined in the namelist but in the domcfg.nc input file.\\

    12221222     3 options are available to represent to ice-shelf/ocean fluxes at the interface: 
     
    12721272 
    12731273        where $T_b$ is the temperature at the interface, $S_b$ the salinity at the interface, $\gamma_T$ and $\gamma_S$ the exchange coefficients for temperature and salt, respectively,  
    1274         $S_i$ the salinity of the ice (assumedto be 0), $h_{isf}$ the ice shelf thickness, $\rho_i$ the density of the iceshelf,  
     1274        $S_i$ the salinity of the ice (assumed to be 0), $h_{isf}$ the ice shelf thickness, $\rho_i$ the density of the iceshelf,  
    12751275        $c_{p,i}$ the specific heat capacity of the ice, $\kappa$ the thermal diffusivity of the ice  
    12761276        and $T_s$ the atmospheric surface temperature (at the ice/air interface, assumed to be -20C).  
     
    13031303     The fluxes and friction velocity are computed using the mean temperature, salinity and velocity in the first \np{rn_htbl}{rn\_htbl} m. 
    13041304     Then, the fluxes are spread over the same thickness (ie over one or several cells). 
    1305      If \np{rn_htbl}{rn\_htbl} larger than top $e_{3}t$, there is no more direct feedback between the freezing point at the interface and the top cell temperature. 
     1305     If \np{rn_htbl}{rn\_htbl} is larger than top $e_{3}t$, there is no more direct feedback between the freezing point at the interface and the top cell temperature. 
    13061306     This can lead to super-cool temperature in the top cell under melting condition. 
    13071307     If \np{rn_htbl}{rn\_htbl} smaller than top $e_{3}t$, the top boundary layer thickness is set to the top cell thickness.\\
