-PALM allows for studying the ocean mixed layer (OML) by using an ocean option where the sea surface is defined at the top of the model, so that negative values of ''z'' indicate the depth. Hereafter, we keep the terminology and use the word ''surface'' and index ''0'' for variables at the sea surface and top of the ocean model. For a list of ocean specific parameters, see the following Table 3.

-The ocean version differs from the atmospheric version by a few modifications, which are handled in the code by distinction of cases, so that both versions share the same basic code. In particular, seawater buoyancy and static stability depend not only on ''θ'', but also on the salinity Sa. In order to account for the effect of salinity on density, a prognostic equation is added for Sa (in PSU, ''practical salinity unit''):

 [#jackett2006 Jackett et al. (2006)]. The algorithm is based on polynomials depending on Sa, ''θ'', and ''p'' (see [#jackett2006 Jackett et al., 2006], Table A2). At the moment, only the initial values of ''p'' enter this equation.\\
 The ocean is driven by prescribed fluxes of momentum, heat and salinity at the top. The boundary conditions at the bottom of the model can be chosen as for atmospheric runs, including the possibility to use topography at the sea bottom.\\
-Note that the current version of the ocean option does not account for the effect of surface waves (e.g., Langmuir circulation and wave-breaking). Parametrization schemes might, however, be provided within the user interface (see Sect. [wiki:doc/tec/user user interface]) and have been used, e.g., by [#noh2004 Noh et al. (2004)]. The ocean option in its current state was recently used for simulations of the ocean mixed layer by [#esau2014 Esau (2014)], who investigated indirect air-sea interactions by means of the atmosphere-ocean coupling scheme that will be described in Sect. [wiki:doc/tec/coupled coupled atmosphere-ocean simulations]. Note that most previous PALM studies of the
-OML used the atmospheric code, subsequent inversion of the ''z''-axis and appropriate normalization of the results, instead of using the
-relatively new ocean option (e.g., [#noh2004 Noh et al., 2004], [#noh2009 2009]).

+The ocean mode is switched on by providing the FORTRAN namelist {{{&ocean_parameters}}} in the input parameter file.
