| 36 | C     The following five CPP options are experimental and aim to deal | 
| 37 | C     with artifacts due to the low-frequency specification of sea-ice | 
| 38 | C     boundary conditions compared to the model forcing frequency. | 
| 39 | C     Ice convergence at edges can cause model to blow up.  The | 
| 40 | C     following CPP option fixes this problem at the expense of less | 
| 41 | C     accurate boundary conditions. |
