In this case, it is possible to define the location of $t$-levels at the middle of cells (\np[=.true.]{ln_dept_mid}{ln\_dept\_mid})

For backward compatibility with version 3.6, by setting \np[=.false.]{ln_e3_dep}{ln\_e3\_dep}

All these above operations are done through statement functions in routine \mdl{domzgr} (\texttt{DOMAINcfg} variant).

The options available to define the closed seas with \texttt{DOMAINcfg} are listed in \nam{dom_clo}{dom\_clo}, while the control on how closed sea net fresh water input will be redistributed by NEMO is described in \autoref{subsec:DOM_closea} and \autoref{sec:MISC_closea}.
