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