 == ''' Detail of the implementation''' ==
 
-...
+A new copy of the model has to be compiled with a configuration based on ORCA2_SAS_LIM.
+However no namelist parameters need be changed from the settings of the previous run (except perhaps nn_date0)
+In this configuration, a few routines in the standard model are overriden by new versions.
+
+Routines replaced are:
+
+nemogcm.F90
+
+       This routine initialises the rest of the model and repeatedly calls the stp time stepping routine (step.F90)
+       Since the ocean state is not calculated all associated initialisations have been removed.
+
+step.F90
+
+       The main time stepping routine now only needs to call the sbc routine (and a few utility functions).
+
+sbcmod.F90
+
+       This has been cut down and now only calculates surface forcing and the ice model required.  New surface modules
+       that can function when only the surface level of the ocean state is defined can also be added (e.g. icebergs).
+
+daymod.F90
+
+       No ocean restarts are read or written (though the ice model restarts are retained), so calls to restart functions
+       have been removed.  This also means that the calendar cannot be controlled by time in a restart file, so the user
+       must make sure that nn_date0 in the model namelist is correct for his or her purposes.
+
+stpctl.F90
+
+       Since there is no free surface solver, references to it have been removed from stp_ctl.
+
+diawri.F90
+
+       All 3D data have been removed from the output.  The surface temperature, salinity and velocity components (which
+       have been read in) are written along with relevant forcing and ice data.
+
+One new routine has been added:
+
+sbcsas.F90
+
+       This routine initialises the input files needed for reading temperature, salinity and velocity arrays at the surface.
+       These filenames are supplied in namelist namsbc_sas.  Unfortunately because of limitations with the iom module,
+       the full 3D fields from the mean files have to be read in and interpolated in time, before using just the top level.
+       Since fldread is used to read in the data, Interpolation on the Fly may be used to change input data resolution.
