C     The following five CPP options are experimental and aim to deal
C     with artifacts due to the low-frequency specification of sea-ice
C     boundary conditions compared to the model forcing frequency.
C     Ice convergence at edges can cause model to blow up.  The
C     following CPP option fixes this problem at the expense of less
C     accurate boundary conditions.

#undef OBCS_SEAICE_SMOOTH_UVICE_PAR

C     Smooth the tracer sea-ice variables near the edges.
#undef OBCS_SEAICE_SMOOTH_EDGE
