C The following five CPP options are experimental and aim to deal |
44 |
C with artifacts due to the low-frequency specification of sea-ice |
45 |
C boundary conditions compared to the model forcing frequency. |
46 |
C Ice convergence at edges can cause model to blow up. The |

C following CPP option fixes this problem at the expense of less |
48 |
C accurate boundary conditions. |
