 The 1D model option simulates a stand alone water column within the 3D \NEMO\ system.
 It can be applied to the ocean alone or to the ocean-ice system and can include passive tracers or a biogeochemical model.
 It is set up by defining the position of the 1D water column in the grid

 The 1D model is a very useful tool

 \textit{(b)} to investigate suitable parameterisations of unresolved turbulence
