  As the before and now fields are not really compatible (modification of the geometry), the restart time step is prescribed to be an euler time step instead of a leap frog and fields_b = fields_n (only if coupling between ice sheet and ocean).
 
- An option is available to keep trend due to unconservation of Vol./heat/salt to 0 using what is done for runoff with specified T/S. I.e the location and the amount of extra/loss vol./heat/salt is diagnosed, saved and used to come back to a acceptable level of conservation before the next restart time step. The vol./heat/salt is removed/added as close as possible to the source/sink location using the techniques used in sbcrnf to prescribed a source of volume/heat/salt in the runoff. This option is only suitable for global ocean modeling. It has only been tested in the ISOMIP+ 3 and 4 experiments during 5 coupling steps. Only 5, because afterward the sea level was going ridiculously high.

This option is only suitable for global ocean modeling. It has only been tested in the ISOMIP+ 4 experiments during 10 coupling steps. Only 10, because afterward the sea level was going ridiculously high. However, this option leads to a residual circulation (ie, if no external forcing except the isf draft scenario forcing, the conservation option generate a circulation into the domain).
