    550550Most of the namelist options refer to how to specify the Stokes 
    551551surface drift and penetration depth. There are three options: 
    552 \begin{enumerate} 
    553   \item \np{nn\_osm\_wave=0}. Default value in \texttt{namelist\_ref}. In this case the Stokes drift is 
     552\begin{description} 
     553  \item \np{nn\_osm\_wave=0} Default value in \texttt{namelist\_ref}. In this case the Stokes drift is 
    554554      assumed to be parallel to the surface wind stress, with 
    555555      magnitude consistent with a constant turbulent Langmuir number 
     
    560560      of \SI{5 m}. 
    561561  
    562   \item \np{nn\_osm\_wave=1}. In this case the Stokes drift is 
     562  \item \np{nn\_osm\_wave=1} In this case the Stokes drift is 
    563563      assumed to be parallel to the surface wind stress, with 
    564564      magnitude as in the classical Pierson-Moskowitz wind-sea 
     
    567567      depth, following the approach set out in Breivik(XXxx) 
    568568  
    569     \item \np{nn\_osm\_wave=2}. In this case the Stokes drift is 
     569    \item \np{nn\_osm\_wave=2} In this case the Stokes drift is 
    570570      taken from  ECMWF wave model output, though only the component parallel 
    571571      to the wind stress is retained. Significant wave height and 
     
    573573      depth, following the approach set out in Breivik(XXxx). 
    574574 
    575     \end{enumerate} 
     575    \end{description} 
    576576 
    577577    Others refer to the treatment of diffusion and viscosity beneath 
    578578    the surface boundary layer: 
    579 \begin{enumerate} 
    580    \item \np{ln\_kpprimix}.  Default is \np{.true.}. Switches on KPP-style Ri #-dependent 
     579\begin{description} 
     580   \item \np{ln\_kpprimix}  Default is \np{.true.}. Switches on KPP-style Ri \#-dependent 
    581581     mixing below the surface boundary layer. If this is set 
    582582     \np{.true.}  the following variable settings are honoured: 
    583     \item \np{rn\_riinfty}. Critical value of local Ri # below which 
     583    \item \np{rn\_riinfty} Critical value of local Ri \# below which 
    584584      shear instability increases vertical mixing from background value. 
    585     \item \np{rn\_difri}. Critical value of local Ri # below which 
    586       shear instability increases vertical mixing from background value. 
    587   \end{enumerate} 
    588   and the last to diagnostic outputs: 
    589   \begin{list} 
    590     \item \np{ln\_dia\_osm}. Default is \np{.false.}; allows XIOS output of OSMOSIS internal fields. 
    591   \end{list} 
    592  
    593      
    594     Obsolete namelist parameters include: 
    595   \begin{enumerate} 
    596    \item \np{ln\_use\_osm\_la}. With \np{nn\_osm\_wave=0}, 
     585    \item \np{rn\_difri} Maximum value of Ri \#-dependent mixing at $\mathrm{Ri}=0$. 
     586    \item \np{ln\_convmix} If \texttt{.true.} then, where water column is unstable, specify 
     587       diffusivity equal to \np{rn\_dif\_conv} (default value is 1 ms$^{-2}$).  
     588 \end{description} 
     589 Diagnostic output is controlled by: 
     590  \begin{description} 
     591    \item \np{ln\_dia\_osm} Default is \np{.false.}; allows XIOS output of OSMOSIS internal fields. 
     592  \end{description} 
     593Obsolete namelist parameters include: 
     594\begin{description} 
     595   \item \np{ln\_use\_osm\_la} With \np{nn\_osm\_wave=0}, 
    597596      \np{rn\_osm\_dstokes} is always used to specify the Stokes 
    598597      penetration depth. 
    599  
    600     \item \np{nn\_ave}. Choice of averaging method for KPP-style Ri# 
     598   \item \np{nn\_ave} Choice of averaging method for KPP-style Ri# 
    601599      mixing. Not taken account of. 
    602   
    603      \item \np{rn\_osm\_hbl0} 
    604      \item \np{ln\_dia\_osm} 
    605       \end{enumerate} 
     600   \item \np{rn\_osm\_hbl0} Depth of initial boundary layer is now set 
     601     by a desnity criterion similar to that used in   
     602\end{description}
