New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

    15121512are consistent with the numeric of the code, so that the trajectories never intercept the bathymetry.

    18091809The steric effect is therefore not explicitely represented. 
    18101810This approximation does not represent a serious error with respect to the flow field calculated by the model 
    1811 \citep{Greatbatch_JGR94}, but extra attention is required when investigating sea level, 
     1811\citep{greatbatch_JGR94}, but extra attention is required when investigating sea level, 
    18121812as steric changes are an important contribution to local changes in sea level on seasonal and climatic time scales. 
    18131813This is especially true for investigation into sea level rise due to global warming. 
    18141814 
    18151815Fortunately, the steric contribution to the sea level consists of a spatially uniform component that 
    1816 can be diagnosed by considering the mass budget of the world ocean \citep{Greatbatch_JGR94}. 
     1816can be diagnosed by considering the mass budget of the world ocean \citep{greatbatch_JGR94}. 
    18171817In order to better understand how global mean sea level evolves and thus how the steric sea level can be diagnosed, 
    18181818we compare, in the following, the non-Boussinesq and Boussinesq cases. 
     
    18881888the ocean surface, not by changes in mean mass of the ocean: the steric effect is missing in a Boussinesq fluid. 
    18891889 
    1890 Nevertheless, following \citep{Greatbatch_JGR94}, the steric effect on the volume can be diagnosed by

    18911891considering the mass budget of the ocean.  
    18921892The apparent changes in $\mathcal{M}$, mass of the ocean, which are not induced by surface mass flux 
    18931893must be compensated by a spatially uniform change in the mean sea level due to expansion/contraction of the ocean 
    1894 \citep{Greatbatch_JGR94}.

    18951895In others words, the Boussinesq mass, $\mathcal{M}_o$, can be related to $\mathcal{M}$, 
    18961896the total mass of the ocean seen by the Boussinesq model, via the steric contribution to the sea level, 
     
    19241924This value is a sensible choice for the reference density used in a Boussinesq ocean climate model since, 
    19251925with the exception of only a small percentage of the ocean, density in the World Ocean varies by no more than 
    1926 2$\%$ from this value (\cite{Gill1982}, page 47). 
     19262$\%$ from this value (\cite{gill_bk82}, page 47).

    19281928Second, we have assumed here that the total ocean surface, $\mathcal{A}$, 
     
    19541954so that there are no associated ocean currents. 
    19551955Hence, the dynamically relevant sea level is the effective sea level, 
    1956 \ie the sea level as if sea ice (and snow) were converted to liquid seawater \citep{Campin_al_OM08}. 
     1956\ie the sea level as if sea ice (and snow) were converted to liquid seawater \citep{campin.marshall.ea_OM08}. 
    19571957However, in the current version of \NEMO the sea-ice is levitating above the ocean without mass exchanges between 
    19581958ice and ocean. 
     
    19861986Among the available diagnostics the following ones are obtained when defining the \key{diahth} CPP key: 
    19871987 
    1988 - the mixed layer depth (based on a density criterion \citep{de_Boyer_Montegut_al_JGR04}) (\mdl{diahth})

    19901990- the turbocline depth (based on a turbulent mixing coefficient criterion) (\mdl{diahth})
