 Parameter to switch on ocean runs.\\\\
 By default PALM is configured to simulate atmospheric flows. However, starting from version 3.3, '''ocean''' = ''.T.'' allows simulation of ocean turbulent flows. Setting this switch has several effects:\\\\
-    * An additional prognostic equation for salinity is solved.\\
-    * Potential temperature in buoyancy and stability-related terms is replaced by potential density.\\
-    * Potential density is calculated from the equation of state for seawater after each timestep, using the algorithm proposed by Jackett et al. (2006, J. Atmos. Oceanic Technol., '''23''', 1709-1728).\\
-      So far, only the initial hydrostatic pressure is entered into this equation.\\
-    * z=0 (sea surface) is assumed at the model top (vertical grid index k=[#nzt nzt] on the w-grid), with negative values of z indicating the depth.\\
-    * Initial profiles are constructed (e.g. from [#pt_vertical_gradient pt_vertical_gradient] / [#pt_vertical_gradient_level pt_vertical_gradient_level]) starting from the sea surface, using surface values given by [#pt_surface pt_surface], [#sa_surface sa_surface], [#ug_surface ug_surface], and [#vg_surface vg_surface].\\
-    * Zero salinity flux is used as default boundary condition at the bottom of the sea.\\

 This parameter is used to switch on a damping layer for the 1d-model, which is generally needed for the damping of inertia oscillations. Damping is done by gradually increasing the value of the eddy diffusivities about 10% per vertical grid level (starting with the value at the height given by '''damp_level_1d''', or possibly from the next grid pint above), i.e. K,,m,,(k+1) = 1.1 * K,,m,,(k). The values of K,,m,, are limited to 10 m^2^/s at maximum.\\\\
 This parameter only comes into effect if the 1d-model is switched on for the initialization of the 3d-model using [#initializing_actions initializing_actions] = '' 'set_1d-model_profiles'.''
